5 Developments in Nanotechnology Transforming Stem

Home Assignment Answers 5 Developments in Nanotechnology Transforming Stem

Nanotechnology is a field in which is capable of pushing the boundaries of the technological practices as well as aiding the researchers and engineers in improving the current lines of the products and technologies. The major concern here is the popping out of entirely novel functionalities of the bottom-up approach of the construction. The invention of STM (Scanning Tunneling Microscope) is the foundation of the developments in the nanotechnology in the year 1980. The two names behind this the development of the technology are Heinrich Rohrer and Gerd Binning IBM Zurich. The advents in the technology made by these two scientists helped them in winning the Physics’ Nobel Prize of the year 1986. AFM (Atomic Force Microscope) was the precursor to the development of STM. This was the main feature which allowed the scientists in researching the technology at small scales, i.e. nano-level which is 1/10^9m.

  1. Healing of the wounds-

Yes, this process can also be fastened with the help of the technology. Though it is a natural process and well-structured, the healing sequence can be disturbed by several factors. There is the commercial employment of numerous delivery systems based on the technology. The major examples are titanium dioxide, gold, copper, zinc oxide, silver, E. coli. The repairing of the damaged tissues of the skin and the regeneration of the bioactive molecules are used in combination. Till now, animals have been the source of this practical knowledge because they have been tested with the biomaterials such as collagen, chitosan, and polylactic acid. The response of the test was wound contraction and epithelialization.

  1. Treatment of diabetes-

The advent of nanotechnology, the employment of artificial pancreas has helped in the treatment of diabetes mellitus. Earlier, the transplantation of pancreas was the option. Here, with the applications of the technology brings the use of the beta cells. Biodegradable polymer nanospheres are used for the oral delivery of insulin for bypass gastric acids.

  1. Assistance in reproduction-

Nanotechnology aims for treating diseases and preserve the fertility of the couples. Nanotechnology has set the foundation of assisted reproductive technology (ART). The main objective is the achievement of the pace as well as the treatment of infertility done with the help of non-invasive detection and diagnosis. The research for identifying nucleic acids, nitrogen species, antigens and reactive oxygen has been carried on by the development of nanobiosensors. The main motive of the research is enhanced sensitivity and increased speed.

  1. Electronic materials’ reconfiguration-

The reconfiguration of chemical composition can be reversed by controlling the distribution of internal ion in a solid-state film after the fabrication of the device. Using an applied electric field at the room temperature helps. The technology also aids in the reconfiguration of the dielectric films and the development of the new devices’ concepts like RAM.

  1. Farming usage-

Now the farmers can use nano-fertilizers which are made up of the nano-coated fertilizers, engineered metal oxide and nano-sized nutrients. The main aim of the use of the traditional active ingredients or the inorganic nanomaterial is the procurement of the biological efficiency without any overdosage.

Another important topic which you should read to have a clear understanding of the concept is: Developments in Nanotechnology- Impact on Society
