Nanotechnology is based upon the principles of controlling atomic and molecular level matter. It helps a lot in the production of new materials. This has proved very useful in medicine and electronics. Nanometer which is equal to one billionth of a meter is used as a unit for nanotechnology. Now when you have to work on such a minute level then several advantages will come up as compared to conventional technology. Nanotechnology is all about with the application of devices and tools that are in the range of 1-100 nanometers in size. The average user must have access to use this technology as it has several benefits.
This technology is in use and it is ever increasing in today’s technologically advanced world. With the help of nanotechnology, many devices and mechanisms have been formed that cures some of the dreadful diseases like cancer. Nanotechnology passes through nascent stages and making expeditious progress in medicine. The major contribution of this technology is in science and the benefits in this area are briefed up here:
Body Cells repairing becomes Easy:
The formation of miniscule devices and robots that are proficient to enter into the human body and do various functions is done by using nanotechnology as it repairs cells. A molecular machine is the other name given to the miniscule devices. These machines help to carry the process of cell repair as one body cell differs from another cell. Nanobots help to repair the damaged heart tissues and unclogging of cholesterol filled arteries. In ancient times, bone injuries take time to heal as scaffold tools were used in bone healing, but now with the help of polymer scaffolds which have stem cells, the bone injuries can be healed in a shorter time than before.
Efficient and effective Drug Delivery:
In conventional medical systems, all medicine delivery system has to be organized manually .These medicine delivery systems consist of oral intake of medicines, injections and other modes of manual drug delivery which is always subject to human mistake. Some medicines need to be taken at a particular time and with a particular gap. So thanks to nanotechnology as it is now possible only with the help of nanovehicles. Some of the famous nanovehicles are microchips, layered assembled systems, micro needle-based transdermal therapeutic systems etc… Some machines like polymer micelles, liposomes and dendrimers, etc. were available in the 1960s in a bigger form and now the miniature forms of these machines are available.
Replaces Abnormal Genes:
As the devices of nanotechnology are very small which proves very useful for the replacement of cells responsible for disease or any abnormality. This technology can be used for the replacement of the abnormal genes with normal and healthier genes. A team of expert scientists that were from the California Institute of technology in Pasadena have done an experiment for gene therapy. A polymer made nanobots which are covered by a protein known as transferring was used in this experiment. The therapy that was developed by them is known as “RNA interference”. It helps to block the proteins which are responsible for diseases like cancer.
Noninvasive Imaging Tools:
Molecular imaging techniques are used for imaging in nanotechnology. Although, this technique is not used as a replacement for existing imaging techniques but it complements these imaging techniques and gives more accurate results. This leads to depiction of actual processes of a disease at a molecular level.
Transformation of Stem Cells: Stem cells have the capability to transform the cells to do some specialized functions. So nanotechnology is used to transform stem cells into some special cells and these special cells help to achieve the desired results.
It is true that the science of nanotechnology has rendered many options for the treatment of disease, repairing of cells, gene therapy etc… The scope of development in the Nanomedicine is huge due to the technological developments taking place rapidly in this area.
