A tutorial review on bimetallic nanoparticles loaded in smart organic polymer microgels/hydrogels

The bimetallic nanoparticles and smart microgels/hydrogels are a particularly interesting combination that have received a lot of attention over the past ten years. These composite materials (bimetallic nanoparticles loaded in smart microgels/hydrogels) are a worthy candidate for a wide range of biological, environmental, and catalytic applications due to the sensitive behavior of microgels in their hybrid systems. There are numerous morphologies and architectural designs for hybrid microgels based on bimetallic nanoparticles reported in the literature. The morphology of microgels in hybrid systems is the key for their usage. For this reason, a specific assembly of hybrid microgels based on bimetallic nanoparticles is designed, specifically, for a particular purpose. This article reviews current developments in the synthesis, classification, characterization, properties, and applications of bimetallic nanoparticles loaded in microgels. The applications of bimetallic nanoparticles loaded in microgels in the environment, biomedicine, sensing, and catalysis have been covered in a tutorial approach.
