Nanotechnology is currently being considered to be of great help not only in the electronic but also in the medical world. In the past few years, nanotechnology is being used in microelectronics, sunscreens, drugs, and so many other products. The nanoparticles are found to be ending up in the environment in enormous amounts and there is no idea about its long-term effects. The nanoparticles have been found to have a bigger impact on the environment by the researchers from the National Science Foundation Center for Sustainable Nanotechnology.
The researchers found common, non-disease-causing bacteria called Shewanella oneidensis MR-1 to gain resistance when repeatedly exposed to nanoparticles found in lithium-ion batteries used in portable electronics and electric vehicles. The bacteria were found to change their biology and biochemistry in order to survive in the presence of nanoparticles. The asbestos or DDT have also been found to cause problems as materials like these contain non-antibacterial nanoparticles that causes resistance in bacteria. The nanoparticles have always been used to kill microbes but the sudden gain of resistance is a complete shock. The human-made bacteria are also proving to be a threat to society looking at the increase in resistance among bacteria.
Just like the bacterial resistance gained through the nanoparticle, the University of Bath researchers have found the bacteria to gain resistance not only due to exposure to a certain product on a frequent or higher concentration but also due to the transfer of genetic code using microbes as the medium. The microbes like Enterococcus faecalis are found to help transfer a completely new genetic code rather than just altering through a simple mutation in the bacteria-causing infection. The transfer of completely new information is found to help spread resistance at a faster rate and make a killing of the harmful bacteria all the more difficult.
