Context: Bodoland University’s collaborative work on fungus-powered biosynthesised nanogold particles earns international patent.

About Cordy gold nanoparticles:

  • Cordy gold nanoparticles (Cor-AuNPs), the outcome of a collaborative experiment by scientists from four Indian institutions, has earned an international patent from Germany.
  • These nanoparticles, derived from the synthesis of the extracts of Cordyceps militaris and gold salts, could make drug delivery in the human body faster and surer.
  • Cordyceps militaris is a high-value parasitic fungus.
  • Gold salts are ionic chemical compounds of gold generally used in medicine.
  • Penetration in the cells is more when the drug particles are smaller.
  • Cordyceps militaris, called super mushroom for its tremendous medicinal properties, adds bioactive components to the synthesis of gold nanoparticles for better penetration.
  • The wild Cordyceps mushroom is found in the eastern Himalayan belt.
  • 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.

About Cordyceps militaris:

  • Cordyceps militaris is a species of fungus in the family Cordycipitaceae, and the type species of the genus Cordyceps.
  • It was originally described by Carl Linnaeus in 1753 as Clavaria militaris.
  • Cordyceps militaris is entomopathogenic fungus, i.e., it parasitizes insects.
  • It can be cultivated in a variety of media, including silkworm pupae, rice, and liquid nutrition.
  • It is a potential harbourer of bio-metabolites for herbal drugs and there is evidence from ancient times for its applications for revitalization of various systems of the body.
  • It contains a protein CMP18 which induces apoptosis in vitro via a mitochondrion-dependent pathway.
