Layer by Layer Assembly

Layer by Layer assembly is the construction of nanometer-scale coatings by the adsorption of alternately charged polyions, and it can be used on arbitrarily shaped objects. One example of its use include the construction of nano-coated microspheres for targeted drug delivery in which the nanocoating defines both the diffusion of the drug and the surface characteristics that provide targeting. Other applications in process at Louisiana Tech are the construction of coated microchannels for platelet adhesion studies and the development of fluorescence-based microsensors.
