Nanotech May Have Use in Cancer Hyperthermia

An exciting development in nanotechnology in the biomedical field is the use of fungal extracts in nanoparticle synthesis, wherein large concentrations of gold and magnetite nanoparticles have been obtained. These nanoparticles have potential application in cancer hyperthermia and drug delivery, said Absar Ahmad, senior scientist at the biochemical sciences division of the National Chemical Laboratory, on Thursday.

Ahmad was speaking at the national conference ‘Nanobiotechology: Applications and Prospects’ organised by the department of microbiology at Abeda Inamdar Senior College.

“Gold and magnetite nanoparticles have potential biomedical applicability. The conjugate nanoparticles are made for targeted drug delivery,”

In the laboratory, the use of microorganisms such as fungi in the synthesis of nanomaterials is investigated over a range of chemical compositions, Ahmad said. The research work on nanoparticles was started in 2000. Now, companies have to take it up for commercialisation, he said.

Devipriya Rabin Mazumder, head of the department of microbiology, said that nanotechnology may have a huge impact on the medical industry. “There’s even speculation that nanorobots could slow or reverse the ageing process and life expectancy could increase significantly. The technology has the potential to have a positive effect on the environment also. For instance, scientists could programme airborne nanorobots to rebuild the thinning ozone layers,” she said.

Experts highlighted that smart nano-delivery systems are under various stages of development for sustained, targeted and triggered release of drugs and genes at the target cells, thus reducing side-effects, doses and frequency of administration of the drugs.

In the three-day conference, the focus is on the emerging branch of nanotechnology that derives its inspiration from biology. It provides a forum for researchers, teachers and students to learn about the developments in this rapidly developing field.
