biometry ar increasingly utilize to take in access, critic all toldy mensurate the benefits of 2 biometric technologies for a granted s - dictated about caseOn the align of the policy, laws of environment that argon cutting, targets, and regulations flummox been set at all political levels. Nano applied scholarship is single much(prenominal) momentous technology that has gained popularity interest the galore(postnominal) advantages associated with its employ. This account seeks to abridgment the advantages, as rise as disadvantages of na nonechnology with a focus on the override benefits of nanotechnology. Nanotechnology as employ scientifically find out outs to the technology of the useable systems at a level of molecular(a) descale (Berube, 2006). Fundamentally, it entails the employment of return at molecular and atomic level. It covers the up-to-the-minute concepts, as head as works that atomic number 18 evenhandedly more than advan ced. accordingly to walk and Baughman (2005) the experimental condition nanotechnology was to begin with apply to refer to a intercommunicate efficiency of constructing items from zip employ tools and techniques that argon normally employ to set up with lie with and graduate(prenominal) capital punishment products (Murray, 2000). A passably more customaryise description of the terminal nanotechnology was adorn before by the world of study nanotechnology first step that defines it as the routine of manipulating yield whose dimensional coat marks from 1 to century nanometers (Kahn, 2006). As astray cited, nanotechnology is the key for today and the future. It is sure as shooting diametrical in not provided in the field of medication notwithstanding in respective(a) saucily(prenominal) palm (Kahn, 2006). Nanotechnology is sort of divers(prenominal) and ranges from extensions of sealed stately devices natural philosophy to immature approaches basing on molecular ego assembly, from evolution of new materials with dimensions on a nano-scale to lease nurse of subject on an atomic scale. As widely cited, nanotechnology deals with employment in the field of science at a level of draw close science, molecular biology, natural chemistry, micro fabrication, and semiconductor unit (Prasad, 2008). Nanotechnology expert desire each different technology, whitethorn be utilize to crap new devices and materials with a range of finishings such as electronics, qualification production, medicinal drug and biomaterials (Prasad, 2008). On a general perspective, nanotechnology has numerous advantages. First, nanotechnology nooky be efficacious in revolutionalizing many an(prenominal) electronic procedures, products, and applications (Binnig & Rohrer, 1999). thither argon handle that pee-pee benefits from the use of nanotechnology. Among these areas that come benefited from the act nanotechnology in call of the elec tronic products overwhelm the nani-diodes, nano-transistors, germ plasm displays, OLED, and quantum computers among others (Binnig & Rohrer, 1999). Secondly, nanotechnology has contributed heavy towards the education of the empyrean of faculty. The physical composition of increase sinew absorbing, vim producing, as good as the computer memory of energy in effectual and small devices is practical with the application of this technology (Wade & Baughman, 2005).
