ABSTRACT
Above and beyond the copyright issues of ideas, a large portion of nanoscience innovations is an attempt to imitate what has evolved in Nature. Living organisms are not just a compilation of nanoscale objects: Atoms and molecules are organized in hierarchical structures and dynamic systems that are the outcomes of millions of years of Mother Nature’s experiments (Weiss et al., 2006). Of course, all physiological processes on some level occur at the submicron, nanometer, and even smaller picometer scale. The essential biomolecules such as sugars, amino acids, hormones, and DNA are in the nanometer range. Tenth-nanometer diameter ions such as potassium and sodium generate nerve impulses. Most protein and polysaccharide molecules have nanoscale dimensions. Every living organism on earth exists owing to the presence, absence, concentration, location, and interaction of these nanostructures (Weiss et al., 2006; Ravichandran, 2010).
