If bacteria and fungi can give trouble, they can cure diseases like cancer and AIDS as well.
LUCKNOW: They can be both the cause as well as the cure. If bacteria and fungi can give trouble, they can cure diseases like cancer and AIDS as well. Talking to TOI, Absar Ahmed, a scientist at the National Chemical Laboratory, Pune, stated that bacteria can be used for preparing a medicine that can cure cancer. 'Actinomycetes,' a bacterium, when put into a solution of yellow gold or bulk gold, changes its colour into purple within 24 hours as it gets converted into nano form.
These gold nano particles can be used in cancer treatment as it can absorb infrared rays and the heat is sufficient to kill the tumour growth, he said.
He added that out of 500 species of 'actinimycetes,' only one called 'Thermonanospora' is found effective in killing tumour growth. He also stated that nano particles made from bacteria are more stable in comparison to those who were chemically made. Another form in which they can be used for cancer treatment is 'magnetite nano particles.' These magnetite particles are incubated in the anti-cancer drugs and then the drug is injected to the body.
When the magnetic field is applied, these particles concentrate at the point which is affected. Speaking about how these magnetic nano particles are made, he revealed that fungus is dissolved in the solution of potassium fero and feri cyanide and when filtered after 24 hours, the fungus gets converted into magnetic nano particles. Talking about the toxicity, he stated that it is not toxic as any nano particle which is less than 50nm size automatically gets filtered through the kidney and an experiment found that the size of the particle is 20nm. Texus Bacata, a tree from which people isolate 'texal,' is effective for breast cancer. But 'texal' could be isolated only from a tree which is nearly 100 years old. "We have found a novel way," he stated. "We now isolate 'texal' from the fungus of the same plant which can be used for cancer treatment. We are isolating protein from medicinal plants which can be used to treat AIDS," he added. "We have already filed patents for nanoparticles and within two or three months, we will file patents for these medicines also," added Ahmad. Ahmad was here to deliver his lecture in the 'National Seminar on Nanotechnology: The Road Ahead' which is jointly being organised by National Botanical Research Institute and Amity, Lucknow campus.
