Hollow microgels and their hybrids: classification, synthesis, characterization, properties and applications

Abstract

Abstract Hollow microgels and their hybrids have gained much attention in modern-day research because of their fascinating properties and potential applications. This article gives classification, preparation methods, properties and applications of hollow microgels and their hybrids in modern research. Some of the hollow microgels and their hybrids respond to change in specific environmental stimuli like pH, ionic strength and temperature of the medium. They are called smart polymer hollow microgels and smart hybrid microgels, respectively. This peculiar behaviour makes them a suitable candidate for their use in drug delivery, sensing, catalysis and many other fields. This review represents the current advancement along with future perspectives and suggestions for further research in this particular area.
