The potential for nanotechnology to transform modern life has been appreciated for several years. Generally, nanotechnology involves objects with at least one dimension of less than 100 nm. Such stuff is abundant in the natural world, and one of the most exciting current areas in nanoscience research is the use of proteins as nanoscale components of high-performance devices and as nanosized tools in their own right. Biochemists, with our relatively sophisticated and mature toolkit for understanding protein structure and function, are now saddling up to explore the wild frontiers of biological nanotechnology.
