GNPs have been synthesized successfully by National Centre for Polar and Ocean Research and the Goa University using psychrotolerant Antarctic bacteria.
Properties of GNPs
They are Biocompatible
These have high surface area
They are relatively Stable and Non-toxic.
Can be melted at much lower temperatures (300 °C) than bulk gold (1064 °C).
Have greater solar radiation absorbing ability.
Applications of GNPs
Can be used as composite therapeutic agent in clinical trials, especially in anti-cancer, anti-viral, anti-diabetic, and cholesterol-lowering drugs.
Can be used in the photovoltaic cell manufacturing industry.
Suitable in therapeutic use including detection and diagnosis of diseases, bio-labeling, and targeted drug delivery.
As nano-carriers, 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, eg- NOMFET (Nanoparticle Organic Memory Field-Effect Transistor)
