Abstract :In this study, we developed a nanoplasmonic-based sensor design, which was constructed with a bio-inspired silk material and plasmonic materials insert ignore into journalissuearticles values(gold nanoparticles);. We characterized this mutual integration at molecular level by using Atomic Force Microscopy, Scanning Electron Microscopy, as well as the chemical composition was confirmed with Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy and X-Ray Photoelectron Spectroscopy analyses, along with contact angle measurements for hydrophilicity/hydrophobicity evaluation. Once a single layer of silk-gold nanoparticle mixture was accomplished, we serially applied an adlayer and plasmonic material to create more sensitive surface. Accordingly, we benchmarked the performance of the multi-layer sensor system, and observed ~6.8 times insert ignore into journalissuearticles values(or red-shifts from 7.93 nm to 12.90 nm); signal improvements compared to the one developed by a single layer. In sum, we here presented insert ignore into journalissuearticles values(i); a facile drop-casting method for developing a nanoplasmonic sensor design, insert ignore into journalissuearticles values(ii); the use of inexpensive off-the-shelf plastic as a substrate, insert ignore into journalissuearticles values(iii); easy-to-adapt strategy with standard spectrometer devices, and insert ignore into journalissuearticles values(iv); minimum training for its proper use.
