AB  - Hydrogels have peculiar physical and chemical properties and therefore, are used in a variety of biomedical applications including drug delivery agents, prosthetic devices, the repair and replacement of soft tissues, contact lenses, etc. Consequently, investigation of mechanical, physical and chemical properties is crucial in biomedical application of hydrogels. Poly (2-hydroxyethyl methacrylate) (pHEMA), as a biocompatible hydrogel, was first hydrogel used for making soft contact lenses. Many researches have been modified pHEMA with the aim of improving its properties. Application of nanotechnology is one of the possible solutions for improving the characteristics of this biocompatible hydrogel. In this paper, polyhydroxyethyl methacrylate was used as standard material for soft contact lenses (SL 38). This material was incorporated with fullerene C60 (SL38-A), fullerol C60(OH)24 (SL 38-B) and fullerene metformin hydroxylate C60(OH)12(OC4N5H10)12 (SL 38-C), respectively. Three new nanophotonic soft contact lenses were made. The main goal of this research was to develop appropriate process parameters for soft contact lens micro-turning. Also, studying the thermal decomposition of standard soft contact lens, pHEMA, as well as three new nanophotonic soft contact lenses was one of the main objectives. Results have shown that manufacturing process of nanofotonic soft contact lens is considered to be a micro-turning process regarding the cutting depth and tool nose ratio. Thermal stability of all three nanofotonic soft contact lenses was significantly improved comparing to the standard soft contact lens. Still, further research needs to be done so these nonophotonic soft contact lenses could find practical application in the field of biomedical engineering.

AB  - The stable isomer of the higher fullerene C84 of D2 symmetry was isolated from carbon soot by the new advanced extraction and chromatographic methods and processes. Characteriyation of the isolated C84-D2:22 was performed by the FT-IR(KBr) method, over the relevant region from 400 to 2000 cm-1, in the absorption mode. A series of various characteristic, dominant and new absorption maxima of this fullerene was registered and confirmed. All the observed infrared absorption bands are in excellent agreement with the theoretical calculations for this molecule. The molar absorptivity, ε, as well as the integrated molar absorptivity, ψ, of its IR absorption bands were determined in adequate and different spectral regions.

AB  - The aim of this study was to develop new soft contact lens (SCL) materials which would, after recommended and existing machining processes, improve surface roughness. Nanomaterials (fullerene, fullerol and methformin hydroxylate fullerene) were incorporated into commercial material for SCL (SL38) based on PHEMA, which were derived by the technology in the production lab of the company Soleko (Milan, Italy). Nanophotonic SCLs (SL38-A, SL38-B, SL38-C, respectively) were produced in the company Optix (Belgrade, Serbia) from the obtained materials. For the surface characterization of SCLs, AFM analysis and lacunarity method were performed. The results showed that for the SL38-B average roughness value is lower than those of SL38-A and SL38. The topography parameters of SL38-C were between the parameters of SL38-A and SL38-B. Lacunarity analysis of AFM images confirmed that SCLs surface state should belong to either group of adequate (slanted p-diagram) or inadequate (contorted p-diagram) roughness concerning tear film stability. Nanophotonic SCL SL38-C exibits more acceptable performance considering SCL surface functional behavior as compared to other SCLs. The positive result of incorporating nanomaterials into basic material for SCL is better quality of the nanophotonic SCLs surfaces. On the bases of these experiments, the assumption that incorporation of fullerene derivate will not increase surface roughness parameters is confirmed.

AB  - The aim was to develop new materials that would, after appropriate machining processes, improve the surface roughness and wettability of contact lenses. The samples used in this investigation were standard rigid gas-permeable (RGP) SOLEKO contact lenses, made of poly-MMA-co-siloxy silane methacrylate material (known under the commercial name SP40 (TM)), and its modifications by adding three nanomaterials: fullerene C-60 (designated as SP40-A), fullerol C-60(OH)(24) (designated as SP40-B) and methformin hydroxylate fullerene C-60(OH)(12)(OC4N5H10)(12) (designated as SP40-C). Both atomic force microscopy (AFM) and magnetic force microscopy (MFM) were used to measure the topography and gradient of the magnetic field of the nanophotonic materials and the reference samples. According to the magnetic properties of all the materials yielded by MFM it can be concluded that adding fullerene and its derivatives certainly reduces the spectrum of the phase shifts angle by almost 50 %, which increases the paramagnetic characteristics of the nanophotonic material. The positive result of nanophotonic materials characterization is the fact that the roughness parameter values for all of these materials, are lower than those for the basic material. A surface lacunarity analysis, based on in-house procedures for determining the lacunarity value of contact lens surfaces, confirms the influence of surface topology on the tear film volume distribution and, consequently, the contact lens' surface lubrication. The presence of carbon nanomaterials, according to the surface roughness parameters, are improved for rigid gas-permeable (RGP) contact lenses made from nanophotonic polymer materials compared to those produced from the basic material.

AB  - U radu su predstavljeni rezultati komparativnih istraživanja optičke snage mekih kontaktnih sočiva (MKS) sa različitim tehnikama mjerenja koje se koriste pri finalnoj obradi kontaktnih sočiva. Tri vrste nanofotoničnih mekih kontaktnih sočiva su napravljene od standardnog polimacon materijala (Soleko SP38TM) sa inkorporiranim fulerenom C60, fulerolom C60(OH)24 i fuleren-metformin-hidroksilatom C60(OH)12(OC4N5H10)12. Za potrebe karakterizacije materijala za potencijalnu primjenu kod mekih kontaktnih sočiva, mjerena su optička svojstva mekih kontaktnih sočiva Rotleks i Nidek uređajem. Sa Rotleks uređajem dobijeni su sledeći optički rezultati: optička snaga i mapa defekata, a sa Nidek uređajem: optička snaga, snaga cilindra i ugao cilindra. Dobijene vrijednosti optičke snage i mape defekata pokazali su da optička snaga sintetisanih nanofotoničnih mekih kontaktnih sočiva je identična nominalnoj vrijednosti, dok to nije bio slučaj za standardna meka kontaktna sočiva. Takođe, kvalitet nanofotoničnih mekih kontaktnih sočiva je bolji nego kod standardnih mekih kontaktnih sočiva. Iz prikazanog se može zaključiti da je moguće sintetisati nova nanofotonična meka kontaktna sočiva željenih optičkih karakteristika, što otvara mogućnosti za njihovu primjenu u ovoj oblasti.
AB  - In this paper results of comparative study of the optical power of soft contact lenses (SCL) made of standard material for SCL and nanophotonic materials with different measurement techniques used for the final contact lens controllers are presented. Three types of nanophotonic soft contact lenses were made of standard polymacon material (Soleko SP38 TM) incorporated with fullerene C 60 , fullerol C 60 (OH) 24 and fullerene metformin hydroxylate C 60 (OH) 12 (OC 4 N 5 H 10) 12. For the purposes of material characterization for potential application as soft contact lenses, the optical properties of the soft contact lenses were measured by Rotlex and Nidek device. With Rotlex device the following optical results were obtained: optical power and map of defects, while with the Nidek device: optical power, cylinder power and cylinder axis. The obtained values of optical power and map of defects showed that the optical power of synthesized nanophotonic soft contact lens is same to the nominal value, while this was not the case for the standard soft contact lens. Also, the quality of the nanophotonic soft contact lens is better than the standard one. Hence, it is possible to synthesize new nanophotonic soft contact lenses of desired optical characteristics, implying possibilities for their application in this field.

Two photonic nanomaterials were made by adding fullerene (C60) and fullerol (C60OH24) to the classic, commercially available, base material (PMMApolymethylmethacrylate). Nanomaterials are added to the base material to change the transmission characteristics of light, because of different electromagnetic properties of the materials. Two new nanophotonic nanomaterials, along with the base material were investigated with Scanning Probe Microscopy methods of Atomic Force Microscopy and Magnetic Force Microscopy (AFM/MFM) to determine roughness, electromagnetic properties of materials, and static Force-distance curve for investigating materials mechanical characteristics.

AB  - Since materials on nanoscale have different characteristics from materials on macro scale their biocompatibility should be precisely and specifically investigated. Fullerenes, the third carbon allotrope, are one of the most used nanomaterials. The least stable and the most common is fullerene C-60. One of the main disadvantages of fullerene is its low solubility in water. In order to make it soluble, it must be functionalized with polar groups such as -OH and -COOH. From all the water soluble fullerenes the most important ones are those with -OH groups attached named fullerols. We have developed new materials for contact lenses by adding fullerene (C-60) and fullerol (C-60(OH)(24)) into PMMA. The aim of our investigation was to compare the influences of those materials on aqueous solutions similar to tear film. For the analysis of the solutions we used opto-magnetic imaging and IR spectroscopy. The acquired spectrums were commented and compared with the standard contact lens material, which was analyzed by the same methods. The ISO 10993 cytotoxicity test on extract of nanophotonic material with incorporated C-60 was done as well. This research contributes to better understanding of the biocompatibility of new rigid gas permeable contact lens materials.

AB  - U ovom radu prikazali smo ispitivanje uticaja novih nanofotonskih materijala za kontaktna sočiva na vodene rastvore. Kontaktna sočiva koja smo koristili napravljena su od standardnog materijala siloksanskog akrilata sa ugrađenim molekulama C60 i još jednog materijala sa fulerolom C60(OH)24. Cilj istraživanja je bio da se uporede uticaji tih materijala na različite rastvore, kao što je demineralizovana (18.2 MΩ) voda, alkalna so i kapi za suhe oči. Za analizu različitih rastvora koristili smo optomagnetnu spektroskopiju. Dobijeni spektri su komentarisani i upoređeni sa standardnim materijalom za kontaktna sočiva, koji je analiziran istom metodom, kako bi se prikazale razlike u uticaju ovog standardnog i novog nanofotonskog materijala. Ovo istraživanje doprinosi boljem razumijevanju biokompatibilnosti novih materijala za kontaktna sočiva.

The contact lenses that we used were made of standard siloxane acrylate material with incorporated molecules C60 and another with fullerol C60(OH)24. The aim of the investigation was to compare the influences of these materials on different solutions, such as aqua purificata, saline and drops for dry eyes. Optomagnetic spectroscopy was used to analyze different solutions. The obtained spectrums were commented on and compared with the standard contact lens material, which was analyzed by using the same method, in order to show the differences in influence of this standard and new nanophotonic material.

AB  - U ovom radu predstavljeno je komparativno ispitivanje topografskih karakteristika potencijalnog novog, fotoničnog nanomaterijala za izradu kontaktnih sočiva i komercijalnog materijala kontaktnih sočiva. Ispitivanje je rađeno mikroskopijom atomskih sila (eng. Atomic Force Microscopy, AFM) koja omogućava uvid u površinske strukture ispitivanog materijala na nanonivou. Korišćen je mikroskop atomskih sila, SPM-5200, firme JEOL iz Japana. Za skeniranje površine uzorka AFM koristi posebno dizajnirane fizičke sonde koje se sastoje od šiljka postavljenog na mikronosač (kantilever). Skeniranje površine zasniva se na prevlačenju sonde po površini uzorka i praćenja njene deformacije u cilju dobijanja slika topografije. Sonda korišćena u ovom radu nosi naziv NCS18/Co-Cr i proizvod je firme MikroMasch (Estonija). NCS18/Co-Cr je silicijumska sonda, sa vrhom u obliku konusa. Silicijumski vrh obložen je prevlakom od legure kobalt-hroma. Bazni, komercijalni, materijal kontaktnih sočiva u osnovi je izrađen od polimetilmetakrilata (PMMA), dok je fotonični nanomaterijal kombinacija baznog materijala i fulerena C60. Fulereni su upotrebljeni zbog njihovih dobrih transmisionih osobina u ultraljubičastom, vidljivom i bliskom infracrvenom spektru. Sva snimanja su obavljena na sobnoj temperaturi. Rezultati ispitivanja i komparacije topografije oba materijala prikazani su u radu.
AB  - In this paper the comparative studies were conducted of the surface areas of nanophotonic contact lens and contact lens made from base material, measured by Nanoprobe Atomic Force Microscope. Nanoprobe atomic force microscopy (AFM) provides information on the size structure on nano scale level, the form of recorded structures (cavities), their distribution of the surface, and the total roughness of the scanned area. The atomic force microscope used in this study is a SPM-5200 of JEOL, Japan. AFM consists of a cantilever with a sharp tip (probe) at its end that is used to scan the specimen surface. Images of the specimen surface are created by measuring the deflection of the cantilever. The cantilever used in this study is produced by MikroMasch (Estonia) by trade name NCS18/Co-Cr. This AFM probe is silicon etched probe tip that has conical shape. It is coated with Co and Cr layers. Images of surface topography were obtained for each type of contact lenses. The base material of contact lens was made from PMMA and the nanopho-tonic contact lens was made of fullerene doped PMMA. Fullerenes were used because of their good transitive characteristics in ultraviolet, visible and near infrared light spectrums. Measurements were done at room temperature. Results of topography for both materials are presented and compared.

AB  - In this paper we present applied physics research results of gas-permeable contact lenses (CL) that are manufactured from fluorosilicone acrylate based material (Boston T type). During contact lenses production the conformation states of polymers belonging to near surface layers of CL surface are changed. Since CL quality crucially depends on surface roughness and optical properties, the properties of surface molecules conformation state and their orientation come into perspective as important factors acting on the molecular level. Therefore, we investigated CL surface by phase contrast atomic force microscopy (PC-AFM), magnetic force microscopy (MFM), and optomagnetic fingerprint (OMF) technique and found out that surface quality and magnetic properties of contact lenses have influence on physical properties of light transmission and that these changes can be detected on the nanolevel of magnetism, as well as optomagnetism. These results carry important biophysically based implications for CL industry, biomedical application industry and applied optical science.
