Nanotechnology is one such significant technology that has gained popularity following the many advantages associated with its use. This paper seeks to outline the advantages, as well as disadvantages of nanotechnology with a focus on the overriding benefits of nanotechnology. Nanotechnology as used scientifically refers to the engineering of the functional systems at a level of molecular scale (Berube, 2006). Fundamentally, it entails the manipulation of matter at molecular and atomic level. It covers the current concepts, as well as works that are somewhat more advanced. Accordingly to Wade and Baughman (2005) the term nanotechnology was originally used to refer to a projected ability of constructing items from nothing using tools and techniques that are commonly used to come up with complete and high performance products (Murray, 2000). A somewhat more generalized definition of the term nanotechnology was put forward by the National nanotechnology Initiative that defines it as the process of manipulating matter whose dimensional size ranges from 1 to 100 nanometers (Kahn, 2006). As widely cited, nanotechnology is the key for today and the future. It is certainly pivotal in not only in the field of medicine but in various other fields (Kahn, 2006). Nanotechnology is quite diverse and ranges from extensions of certain conventional devices physics to new approaches basing on molecular self assembly, from developing of new materials with dimensions on a nano-scale to direct control of matter on an atomic scale. As widely cited, nanotechnology deals with application in the fields of science at a level of surface science, molecular biology, organic chemistry, micro fabrication, and semiconductor (Prasad, 2008). Nanotechnology just like any other technology, may be used to create new devices and materials with a range of applications such as electronics, energy production, medicine and biomaterials (Prasad, 2008). On a general perspective, nanotechnology has numerous advantages. First, nanotechnology can be useful in revolutionalizing many electronic procedures, products, and applications (Binnig & Rohrer, 1999). There are fields that have benefits from the use of nanotechnology. Among these areas that have benefited from the continued nanotechnology in terms of the electronic products include the nani-diodes, nano-transistors, plasma displays, OLED, and quantum computers among others (Binnig & Rohrer, 1999). Secondly, nanotechnology has contributed heavily towards the development of the sector of energy. The establishment of increased energy absorbing, energy producing, as well as the storage of energy in efficient and smaller devices is possible with the application of this technology (Wade & Baughman, 2005). ...Download file to see next pagesRead More
