3. Researchers learn from biology to create new micro-nanoscale devices to better understand life processes at the nanoscale
4. Bio-nanotechnology is concerned with molecular scale properties and applications of biological nanostructures and as such it sits at the interface between the chemical, biological and the physical sciences
15. Protein nanoarrays generated by Dip-Pen Nanolithography are emerging and sooner would evolve into a much power tool in biotechnology
