Stimuli-Responsive Microcapsules for Transport, Controlled Delivery and Release of Metal Ions and Organic Chemical Mediators (B04)

Conventional bioassays apply chemical mediators in average concentrations in solution. This is by no means in a close to natural situation where local concentration maxima around producing organisms appear. The project aims for the design of loaded polymeric microcapsules which are responsive to pH changes and illumination. They will act as point-sources for chemical mediators with spatial resolution and will mimic chemically active microbes that shape their immediate environment through the release of metabolites. The capsules will be applied and evaluated in several collaborations within the CRC.
