Gold nanoparticle

Why in the  news?

Recently, experts have reported that gold nanoparticles used in medicines and beauty products can also help prevent the effects of aging.

Important points:

• Dr. RP Parashar, national president of the Integrated Medical Association (AYUSH), said that gold in 'gold ash' or 'ash form' is easily absorbed by the skin.
• AIMIL, in collaboration with Indian researchers, has developed Sparkling Gold Face Wash by combining 24 carat gold nanoparticles with Kashmiri saffron.
• Along with gold and Kashmiri saffron, rose, lotus and marigold distillates are also added to this face wash.

About gold nanoparticle:

• Gold nanoparticles are also known as 'Swarna Bhasma'.
• Gold nanoparticles are tiny gold particles with a diameter of 1 to 100 nm.
• Once dissolved in water, it is also called colloidal gold.
• It has various medicinal and cosmetic properties, they protect the skin, fight aging, improve metabolism and rejuvenate the body.
• It is known to slow down collagen loss and stimulate cell regeneration.
• It also strengthens the underlying tissues, bones, nerves etc.
• According to Dr. Parashar, the benefits of gold have been recognized for thousands of years in the ancient science of Ayurveda for its regenerative, immuno-modulating, beautifying and healing properties.
• It is known as the key to strength, vitality and youth.

Major applications of gold nanoparticle:

• Electronics applications: Gold nanoparticles are designed for use as conductors in everything from printable inks to electronic chips.
• Nanoscale gold nanoparticles are being used to connect resistors, conductors and other elements of electronic chips.
• Photodynamic therapy: Near-IR absorbing gold nanoparticles produce heat when excited by light at wavelengths of 700 to 800 nm.
• This enables these nanoparticles to eliminate targeted tumors.
• Therapeutic applications: Therapeutic agents can also be coated on the surface of gold nanoparticles.
• The large surface area to volume ratio of gold nanoparticles enables their surface to be coated with hundreds of molecules.
• Sensor Applications: These are used in various types of sensors.
• For example, a colorimetric sensor based on gold nanoparticles can identify whether foods are fit for consumption.
