Microgels are a type of polymer colloid that are composed of crosslinked polymer chains. They have a size on the order of micrometers and are able to swell and deswell in response to external stimuli, such as temperature, pH, and solvent concentration. Microgels have a range of interesting properties, such as tunable viscosity and the ability to self-heal, which make them attractive for a variety of applications, including drug delivery, oil recovery, and water treatment.
This is the introduction.
One of the unique features of microgels is their ability to undergo a reversible phase transition between a swollen and a collapsed state. This transition is driven by changes in the solvent conditions, such as the temperature or pH, and can be exploited for a variety of applications. For example, microgels have been used as pH-sensitive drug delivery systems, where the swelling and collapse of the microgels can be used to control the release of the drug.
