Chameleon-inspired multifunctional plasmonic nanoplatforms for biosensing applications

This article reports the creation and application of a novel glucose-sensing platform inspired by chameleon skin. The platform comprises two outer layers of a nanocomposite plasmonic hydrogel and an inner layer of an electrospun mat. Silver nanocubes embedded in a poly(N-isopropylacrylamide)-based hydrogel network provide thermoresponsive and antibacterial properties. The electrospun mat enhances the system's mechanical and structural properties. The platform's photothermal responsivity and antibacterial properties were evaluated, demonstrating its potential for glucose sensing applications by detecting changes in the optical properties of the silver nanocubes.
