Remote control of bioreactions in multicompartment capsules

Remote control over reactions in multicompartment capsules is investigated. Dual-compartment capsules were constructed by consecutive fabrication of the inner and the outer parts of CaCO(3) microcapsules separated by a polyelectrolyte multilayer IR-sensitized by nanoparticle doping. Upon near-infrared laser illumination the contents of the inner capsules are mixed with the outer one. This research paves the way to a simple method for performing sophisticated bioreactions in confined volumes.
