Lucknow: The expensive gold facial that you wanted but could not afford, will soon be within your budget. Scientists at the National Botanical Research Institute (NBRI) here have developed an eco-friendly way to create nano particles of gold in just one minute.
According to scientist Aradhana Misra, “Gold nano particles can be developed by chemical methods but we have found a non-chemical approach — a green way— to create nanotised gold using Trichoderma viride — a fungus. Quick synthesis of nano particles was possible by the use of the fungi”.
As many as 300 fungi were screened and experimented by the scientists for the creation of nano particles of gold. Different shapes and sizes of gold nano particles were synthesised by the biological method. Trichoderma resulted in the quick synthesis of gold.
Dr Misra heads the four-member team which conducted the study. The study was published recently in an international journal called Scientific Reports.
According to scientists, the quick synthesis of gold nano particles by using Trichoderma viride will not only be an eco-friendly but also a cost-effective method as it would reduce the quantity of gold required significantly.
Nanotised gold is used in less amount giving the same effectiveness and quality.
The scientist explained how in any field, if any material is nanotised, it would be utilised in very little quantity as compared to the quantity otherwise.
For example, if a cosmetic or medicine uses 1 kg of gold normally, it would only use one gram in nanotised form. Nanotised gold is being used for various industrial purposes such as in medicine, cosmetics, and pharmaceuticals, she said.
