About 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.
  • 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.

What is nanotechnology and nanoparticle (NP)?

  • Nanotechnology is a technology that creates new and novel materials through controlled manipulation at a size range of 1 nm (nanometer) to 100 nm (1 nm equals to 10-9 m).
  • NanoParticles are those materials that are at least one dimension smaller than 100 nanometres.
    • NPs have a high surface-to-volume ratio and they can provide tremendous driving force for diffusion, especially at elevated temperatures.

Uses of Gold Nano Particles (GNPs)

  • GNPs are found to have greater solar radiation absorbing ability than the conventional bulk gold, which makes them a better candidate for use in the photovoltaic cell manufacturing industry.
  • GNPs are capable of transferring various drugs made out of peptides, proteins, plasmid DNAs, small interfering RNAs, and chemotherapeutic agents to target diseased cells of the human body.
  • GNPs are also found to be useful in the electronics industry.
