Abstract

Nanoporous gold (np-Au) is a promising nanostructured material with many desirable properties, including large surface area-to-volume ratio, corrosion resistance, high conductivity, and well-studied thiol-based surface chemistry. While np-Au has been used in a variety of applications, from fuel cells to electrochemical sensors, its interface with biology, where many of its exciting applications lie, is surprisingly non-existent. This paper reports on drug delivery from np-Au thin films for modifying cell proliferation in situ. We expect that establishing np-Au as a biomaterial with drug delivery capabilities will create new opportunities for engineering advanced BioMEMS devices that can monitor and modulate biological processes in both in vitro and in vivo settings.
