This book describes the current state of research and development in biomimetic membranes for nanobiotechnology applications. It takes an international perspective on the issue of developing biotechnology applications from an understanding of the biomimetic membrane at the nanoscale. The success of these applications relies on a good understanding of the interaction and incorporation of macromolecules in membranes and the fundamental properties of the membrane itself.

Nanobiotechnology of Biomimetic Membranes describes the current state of research and development in biomimetic membranes for nanobiotechnology applications. The application areas in nanobiotechnology range from novel nanosensors, to novel methods for sorting and delivering bio-active moleculres, to novel drug-delivery systems. The success of these applications relies on a good understanding of the interaction and incorporation of macromoleculres in membranes and the funamental properties of the membrane itself.
