Smart plasmonic hydrogels based on gold and silver nanoparticles for biosensing application

The importance of having a fast, accurate, and reusable track for detection has led to an increase investigation in the field biosensing. Optical biosensing using plasmonic nanoparticles, such as gold silver, introduces localized surface plasmon resonance (LSPR) sensors. LSPR biosensors are progressive their sensing precision limit. Also, possibility tune range by varying size shape particles made them extremely useful. Hydrogels being hydrophilic 3D networks can be beneficial when used matrices, because more efficient biorecognition. Stimuli-responsive hydrogels great candidates, response stimulus recognition detection. This article highlights recent advances combining matrix nanoparticles elements. end capability diversity these novel different applications near future discussed.
