Cell microcarriers and microcapsules of stimuli-responsive polymers.

Cell microcarriers and microcapsules have presented a wide range of potential applications. This article overviews their role in biotechnology with focus on the progress accomplished using stimuli-responsive polymers. Key properties of cell microcarriers and microcapsules are identified, followed by a description of the chemistry and gel formation mechanism of some of the stimuli-responsive polymers used to design them.
