Description:
Nano polymeric beads of polystyrene self-assembled onto a biopolymer film. These beads self-assemble to form a hexagonal close-packed structure and are deposited on the polymeric film through Langmuir Blodgett technique. These structures also resemble the native structure of insect eyes. The nano beads embedded on the film could be applied to various biomedical applications like making dermal patches. The goal of this work is to self-assemble monolayer beads of polymer onto a bio-polymeric film for bio-sensing and biomedical applications.
Funding Source: This work was supported by the North Carolina Biotechnology Center (NCBC) Biotechnology Research Grant and through the generous support of Dr. James Ryan, the Joint School of Nanoscience and Nanoengineering, and the State of North Carolina.
