Social Implications of Nanotechnology: A Review

Journal Title:Asian Journal of Advanced Basic Sciences
ABSTRACT: Nanotechnology has captured the imaginations of Scientists, Engineers and Economists not
only because of the explosion of discoveries at nanoscale, but also because of the potential societal
implications. Nanotechnology promises to be a dominant force in our society in coming decades in roads.
Today, nanotechnology is still in its infancy and only rudimentary nanostructures can be created with some
control. The science of atoms and simple molecules, a one end, and the science of matter from
microstructures to larger scale, on the other, is generally established. The remaining size related challenge is
at the nanoscale roughly between 1and 100 molecules diameters where the fundamental properties of
materials are determined and can be engineered. A revolution has been occurring in science and technology,
based on the recently developed ability to measure, manipulate and organize matter on this scale. Recently
discovered organized structures of matter (such as Carbon Nanotubes, molecular motors, DNA-based
assemblies, quantum dots and molecular switches) and new phenomenous are scientific breakthrough that
merely hints at possible future developments. However formidable challenges remain in fundamental
understanding of the systems on this scale before the potential of nanotechnology can be realized.
Keywords: Nanotechnologists, diffusion, nanofabrication techniques and nanoscientists.
