Present and future prospects for polypeptide multilayer nanofilms in biotechnology and medicine

Polypeptide multilayer nanofilms are a promising nanotechnology for commercial product development because the processes used to prepare them are simple, flexible, reliable, automatable, and scalable. Moreover, these materials can display a remarkable diversity of physical, chemical, and biological properties. Furthermore, the constituents of these nanofilms, in most cases the nanofilms themselves, and the fabrication process are environmentally benign. Nanofilm structure and function can be tailored to address two Grand Challenges of the US National Nanotechnology Initiative.
