Abstract
A layer-by-layer nanoassembly (LbL) allows production of ultrathin films with a precision of 1-2 nm and needed composition across the multilayer. It was used in combination with traditional lithography to develop micropatterns in ordered nanoparticle multilayers. A selective nanoparticle film growth was also demonstrated for microchannel silicon chips. Microfluidic properties of nanoorganized polymer microcapsules were studied with the microchannel device. Nanoorganized microcapsules production: A LbL-assembly of 20-nm thick poly(styrenesulfonate) / poly(allylamine) shell on microtemplates and loading such hollow polyion shells with enzymes allowed fabrication of catalytic "bioreactors," as it was demonstrated for glucose oxidase, hemoglobin, and myoglobin ensembles.
