Influence of Nanomaterial-Based Contact Lenses on Solutions With Different Glucose Concentrations

Abstract

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.
