Architectures of nano-biointerfaces: relevance to future biosensing, environment and energy applications

Abstract

We describe here a layer-by-layer (LbL) technology to generate multi-functional protein-based biointerfaces for construction of novel bioelectronic devices for biomedical, environment and energy applications. LbL is considered as an effective, simple and well suited technique for fabrication of unique functional biointerfaces. Upon combination of nanomaterials such as carbon nanotubes, polyelectrolytes, proteins and various other biomolecules, system fabrication based on LbL creates new insights and concepts for development of novel sensor and energy technologies. We report here on flexibility and versatility of LbL technique to design the hybrid nanobio-catalytic architectures based on interactions of anionic and cationic biomolecular layers for multiple technological applications.
