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. These results are significant for the qualitative and quantitative determination of the C84-D2:22 fullerene either in natural resources in space and on the Earth or in artificially synthesized materials, electronic, optical and biomedical devices, polymers, composites, catalysts, nanowires, batteries, sensors, optical limiters, solar cells, nanophotonic lenses with improved optical absorption characteristics, refraction features and wettability, diagnostic and therapeutic agents, pharmaceutical substances, such as for diabetes, targeted drug delivery, in biomedical engineering, applied optics industry and so forth.

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  - There are a lot of cosmetic products on the market based on nanotechnology. Those products contain nanomaterials since they have many advantages such as improved delivery of active ingredients, stability and photostability of potentially unstable cosmetic ingredients, increased efficacy and tolerance of the skin for various UV filters. Nanomaterials contribute to easiness of application and aesthetic appearance of final products. Although they offer many possibilities, their use demands caution. Nanoparticles have a large surface to volume ratio leading to their reactivity and alteration in biological activity compared to the parent bulk materials. The shape and size of the particles are the cause if their toxic effects, rather than their chemical properties. There are various nanosystems currently in use, in pharmaceutical and cosmetic industry, and many new ones, waiting to be applied. In this article we are going to introduce those who find an application in personal care products such as: liposomes, niosomes, transfersomes, nanoemulsions, solid lipid nanoparticles, polymeric systems, nanocrystals, fullerenes and finally metal oxide nanoparticles.

AB  - The problem of low solubility of fullerene is surpassed by its functionalization with -OH groups making a new molecule called fullerol C-60(OH)(24). Materials used in this study are synthesized by incorporating fullerol into commercial soft contact lens material Definitive74 made by Contamac, UK. Three different mass concentrations of fullerol are used: 0.003%, 0.01% and 0.015%. Hence, three materials are produced and the fourth material, the standard one, was used as a reference sample. The purpose of incorporating fullerol into polymer was to develop new materials for soft contact lenses with improved optical and mechanical characteristics. The magnetic properties of polymers change due to fullerol presence therefore the aim was to show the differences in magnetic properties of the materials before and after the exposure to four different external influences. The measurements of a remanent magnetization of these materials are done by spinner magnetometer, JR-6A.

AB  - Goal of this research is focusing on early detection of high glucose level in blood via eye, using contact lenses, because we have come to conclusion that skin is not the most suitable place for measuring glucose level, considering invasive and expensive techniques. These specific contact lenses, made of biocompatible nano-structured materials, present biosensors for continuous, noninvasive glucose monitoring and other bioanalits which can be found in tears. In this paper we present the comparative studies of the influence of nanomaterial-based contact lenses on five 
solutions with different glucose concentrations. The nanophotonic contact lens and contact lens made from base material were dipped in solutions over a specific period of time, in order to determine their influence on the glucose solutions. The base material of contact lens was made from PMMA and the nanophotonic contact lenses were 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 all solutions 
are presented and compared.

AB  - This paper presents the structural changes that can be identified in low-mineral Aqua Viva water using four separate samples corresponding to different stages of its filling,
1. The stage before final treatment (inlet pipework)
2. After the first treatment phase using polypropylene membrane surface porosity 2.5 μm.
3. After the second treatment phase using polypropylene / glassfibre membrane porosity 0.45 μm.
4. After the final treatment phase using the double polyethersulfone membrane porosity of 0.2 μm.
As a comparative parameter is used demineralized water Aqua Purificata with conductivity of 0,055μS/cm. Characterization of water was done by two methods, Opto-Magnetic and NIR Spectroscopy with Aquaphotomics approach, based 
on the interaction of light and water. Aqua Viva manifests itself as a strong pair -
diamagnetic and its clear structuring occurs only after treatment at the level of 0.2 
μm. Resulting Aquagrams suggest that only the 0.2 μm filter leads to the appear-
ance of an increased number of water dimer and its major reorganization.

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.
AB  - In this paper we present the investigation of influence of new nanophotonic materials for contact lenses on aqueous solutions. 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. This research contributes to a better understanding of biocompatibility of new contact lens materials.
