Nanoparticle–Hydrogel Based Sensors: Synthesis and Applications

Hydrogels are hydrophilic three-dimensional (3D) porous polymer networks that can easily stabilize various nanoparticles. Loading noble metal nanoparticles into a 3D network of hydrogels enhance the synergy components. It also be modified to prepare intelligent materials recognize external stimuli. The combination and produce or new composite has attracted considerable attention as use these in sensors. However, there is limited review literature on nanoparticle–hydrogel-based This paper presents detailed strategies synthesis design composites, latest applications nanoparticle–hydrogel sensing field. Finally, current challenges future development directions sensors proposed.
