Lucknow: The cost of
gold
in your facial or medicines could come down considerably, thanks to the latest work done by scientists at
NBRI
.
Using a non-chemical approach, scientists from the
National Botanical Research Institute
(NBRI) have developed an eco-friendly way to create nano particles of gold in just one minute.
"Gold nano particles can be developed by chemical methods but we have found 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," said scientist Aradhana Mishra, the head of the four-member team which conducted the study. The study was published recently in an international journal called Scientific Reports.
Scientists said that the quick synthesis of gold nanoparticles 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.
Sharma 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 1gm in nanotised form.
Nanotised gold is being used for various industrial purposes such as in medicine, cosmetics, and pharmaceuticals, Mishra added.
"Gold has been used in medicine in ayurveda over a period of time as Swarnabhasma. The cost of the medicines in which gold is used would be significantly reduced with the use of nanotised gold," she added.
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 nanoparticles were synthesised by the biological method. Trichoderma resulted in the quick synthesis of gold.
