Gold-Mushroom Nanoparticle to ease Drug Delivery


From UPSC perspective, the following things are important :

Prelims level: Gold Nanoparticle

Mains level: Not Much


Cordy gold nanoparticles (Cor-AuNPs), the outcome of a collaborative experiment by scientists from four Indian institutions, has earned an international patent from Germany.

What is Cordy gold nanoparticles ?

  • Cordy gold nanoparticles (Cor-AuNPs) are derived from the synthesis of the extracts of Cordyceps militaris and gold salts.
  • They could make drug delivery in the human body faster and surer.
  • Cordyceps militaris 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.

Benefits offered by this nanoparticle

  • Penetration in the cells is more when the drug particles are smaller.
  • Cordyceps militaris adds bioactive components to the synthesis of gold nanoparticles for better penetration.
  • It can be delivered as ointments, tablets, capsules, and in other forms.

Back2Basics: Gold Nanoparticles for Medicines

  • Gold nanoparticles (AuNPs) are small gold particles with a diameter of 1 to 100 nm which, once dispersed in water, are also known as colloidal gold.
  • Functionalized gold nanoparticles with controlled geometrical and optical properties are the subject of intensive studies and biomedical applications.
  • They find applications in genomics, biosensorics, immunoassays, clinical chemistry, laser phototherapy of cancer cells and tumors, the targeted delivery of drugs etc.
