An Automated Device for Layer-by-Layer Coating of Dispersed Superparamagnetic Nanoparticle Templates

Abstract: Polyelectrolyte multilayers as well as Langmuir−Blodgett or layer-by-layer (LbL) assembled films are widely used as nanostructured coatings for chemical sensors, systems for drug delivery etc. The automated devices for fabricating planar films via dipping first appeared in the early 1990s and those for producing surface coatings via spraying in 2009−2010. However, an automated fabrication for dispersed micro-templates has remained non-developed until recently. In this publication the authors introduce an automated device suitable for coating of dispersed superparamagnetic microtemplates via LbL self-assembly.
