DIFFERENT NANOPARTICLES AND THEIR APPLICATIONS :

   Nanoparticle type
                                       Applications


Alumino silicate nano particles
It can be used to reduce bleeding in trauma patients with external wounds by activating the blood clotting mechanism,   causing blood in a wound to clot quickly. Z-Medica is producing a medical gauze that uses aluminosilicate nano particles for use on external wounds. For trauma patients with internal bleeding another way to reduce the blood loss is needed. 
Also the researchers at Chase Western Reserve University are developing polymer nanoparticles that act as synthetic platelets. Lab tests have shown that injection of these synthetic platelets significantly reduces blood loss.

Polyethylene glycol-hydrophilic carbon clusters (PEG-HCC)
They have been shown to absorb free radicals at a much higher rate than the proteins out body uses for this function. This ability to absorb free radicals may reduce the harm that is caused by the release of free radicals after a brain injury.

Iron oxide nano particles
It can be used to improve MRI images of cancer tumours. The nanoparticle is coated with a peptide that binds to a cancer tumour, once the nanoparticles are attached to the tumour the magnetic property of the iron oxide enhances the images from the Magnetic Resonance Imagining scan.

Gold nano particles
A method being developed to fight skin cancer uses gold nanoparticles to which RNA molecules are attached. The nanoparticles are in an ointment that is applied to the skin. The nanoparticles penetrate the skin and the RNA attaches to a cancer related gene, stopping the gene from generating proteins that are used in the growth of skin cancer tumours.

Gold nano particles embedded in a porous manganese oxide
Using gold nanoparticles embedded in a porous manganese oxide as a room temperature catalyst to breakdown volatile organic compounds in air.

A layer of closely spaced palladium nanoparticles that detect hydrogen. When hydrogen is absorbed the palladium nanoparticles swell, causing shorts between nanoparticles which lowers the resistance of the palladium layer.

Quantum Dots (crystalline nano particles) 
Quantum Dots (crystalline nanoparticles) that identify the location of cancer cells in the body.
Gold nano particles with organic molecules
Combining gold nanoparticles with organic molecules to create a transistor known as a NOMFET (Nanoparticle Organic Memory Field-Effect Transistor).

Iron nano particles
Iron nanoparticles used to clean up carbon tetrachloride pollution in ground water.

Silicon nano particles coating
Silicon nanoparticles coating anodes of lithium-ion batteries to increase battery power and reduce recharge time.

Gold nano particles
Gold nanoparticles that allow heat from infrared lasers to be targeted on cancer tumours.

Silicate nano particles 
Silicate nanoparticles used to provide a barrier to gasses (for example oxygen), or moisture in a plastic film used for packaging. This could reduce the possibly of food spoiling or drying out.

Zinc oxide nano particles
Zinc oxide nano particles dispersed in industrial coatings to protect wood, plastic and textiles from exposure to UV rays.

Silicon dioxide crystalline nano particles
Silicon dioxide crystalline nano particles filling gaps between carbon fibres strengthen tennis racquets.

Silver nano particles
Silver nano particles in fabric that kills bacteria making clothing odour-resistant.

Porous silica 
Nano particles used to deliver chemotherapy drugs to cancer cells.
Porous silica nano particles used to deliver chemotherapy drugs to cancer cells.
Semiconductor nano particles 
Semiconductor nano particles applied in a low temperature printing process that results in low cost solar cells.

Iron oxide nano particles

Iron oxide nano particles used to clean arsenic from water wells.

Nano particles, when activated by x-rays, that generate electrons that cause the destruction of cancer cells to which they have attached themselves. This is intended to be used in place radiation therapy with much less damage to healthy tissue.

A nano particle cream that releases nitric oxide gas to fight staph infections.

 Gold-palladium
That can replace expensive and potentially toxic reagents that promote oxidation of aromatic primary alcohols to aldehydes, which is one of the crucial processes in the perfume production.
