Seiffert, S.: Small but Smart: Sensitive Microgel Capsules. Angewandte Chemie - International Edition 52 (2013), p. 11462-11468

Microgel capsules are micrometer-sized particles that consist of a cross-linked and swollen polymer network complexed with additives. These capsules can be actuated by external stimulation if they are formed from sensitive or supramolecular polymer networks. To make this truly useful, it is crucial to control the microgel size, shape, and loading; this can be achieved by droplet-based microfluidic templating.
