Why in news?

Assam’s Bodoland University is part of collaborative research on a fungus-powered biosynthesised nanogold particles that has received an international patent from Germany


  • Medicines may have traces of ultramicroscopic gold powered by a super mushroom for greater efficacy
  • Cordy gold nanoparticles (Cor-AuNPs), are the outcome of a collaborative experiment by scientists from India and Germany.
  • Cor-AuNPs are derived from the synthesis of the extracts of Cordyceps militaris and gold salts.
  • It could make drug delivery in the human body faster and surer
  • It is a high-value parasitic fungus, lab-grown at the Department of Biotechnology’s Technology Incubation Centre (TIC) in Bodoland University
  • Gold salts are ionic chemical compounds of gold generally used in medicine.

Cordyceps militaris

  • They are called super mushroom for its tremendous medicinal properties, adds bioactive components to the synthesis of gold nanoparticles for better penetration
  • They are found in the eastern Himalayan belt
  • It is a potential harbour of bio-metabolites for herbal drugs and evidences are available about its applications for revitalization of various systems of the body from ancient times.
  • The constituents, especially the anti-cancer agent are expected to play evolutionary roles in the pharmacognosy sector in future

What are its uses?

  • Biosynthesised nanogold particles indicate a new application of nanoparticles in the development of therapeutic drugs that can be delivered as ointments, tablets, capsules, and in other forms.

What are Nano gold?

  • Gold nanoparticles are small gold particles with a diameter of 1 to 100 nm which, once dispersed in water, are also known as colloidal gold.
  • It is generally found in a colloidal solution because gold nanoparticles are created by citrate synthesis. This process involves mixing solutions together to result in the precipitation of gold nanoparticles into solution.
