  • Platinum Black Catalyst Platinum Nanopowders

    Customized Metal Platinum Black Catalyst Platinum Nanopowders Platinum is one of noble metals, it is one of the best catalyst and antioxidants, nano platinum ( Pt ) with small particles size, strong, safe, stable, reliable, environmentally friendly, non-toxic, tasteless, harmless, can be widely used in biomedical, Catalytic industry, cosmetic etc. 1. Platinum Nanopowders for biomedical  Hydrogen and nano-platinum have a synergistic effect that can be used in conjunction with the treatment of oxidant stress disorders; Studies have shown that platinum nano particle-mediated photo-thermal effect in the treatment of bone metastases in nude mice can be a good inhibition of bone tumor growth and osteolytic bone destruction; Lactic acid bio-sensor based on nano - platinum black modification for rapid detection, etc.  2. Platinum Nanopowders as catalyst  Nano platinum are widely applied in catalyst part, Nano-platinum powder has excellent bio-catalytic activity, it can be applied to polymer hydrogenation, reduction and synthesis. Nano platinum also can be used as fuel cell catalyst, due to its high cost, due to its high cost, now some use nano nickle to replace the platinum, and some are looking for ways to improve nano platinum efficiency as catalyst in fuel cells to save cost. Last year Chinese researches have developed a superfine platinum nanowire catalyst on the surface of the zigzag, greatly increasing the surface activity and specific surface area of the fuel cell catalyst, increasing its overall catalytic activity by more than 50 times. 3. Platinum Nanopowders for cosmetics Platinum nanoparticles , due to its strong oxidation resistance Platinum can effectively remove free radicals in the human body. Play the anti-aging effect and at the same time to achieve whitening bright. Platinum Nanopowders can also be used for food preservative, car exhaust purification, etc. Nano platinum do have a lot of amazing functions, we cannot list its amazing functions one by one though.  If you're interstsed in Platinum Nanopowders, please feel free to contact us as hwnano@xuzhounano.com. more

Use of Gold nano as medicine and further as a remote control of brain

Gold Nanoparticles have made their way in the medical treatments. A new treatment involves injecting ultra-tiny, gold wrapped spheres in the cancer patients. These nanoparticles are smaller in size as compared to red blood cell hence they start accumulating in the tumor because they slip out of the bloodstream through minute holes which develop in the rapidly growing vessels of the tumor. Once the tumor is adequately filled with the gold nano-particles oncologist starts blasting it with near infrared light. The gold spheres absorb certain wavelengths of infrared light, a property that is used against the cancer cells. And these nanoparticles convert the light into heat within the tumor which then destroys the cancer cells because temperature reaches 104 degrees Fahrenheit due to which the cancer cells deform and disintegrate. Another treatment which uses the gold nanoparticles is the injection of gold bits into the male testicles and then exposing them to laser rays. At a certain temperature this would kill the sperms and provide temporary contraceptive effect. In case the heat is increased beyond a point it may also lead to permanent sterilization of the male. Since it is temporary this method is a reversible contraceptive and it is really useful because nano gold will not disturb the hormones.

Gold nanoparticles may be used to remotely activate brain cells and help to treat the neurological diseases. As per a report has given details of two proposed treatments which involves the use of  gold nano-particles to transform the nerve cells. In one of the treatments a group of researchers used gold nano rods which was attached to precise molecule which was embedded in the nerve cell membranes then infrared light was made to pass through these nano rods which warmed up the rods thus resulting in neurons to fire.

Another experiment was used which heat up when a magnetic field passes over them. Using whose neurons were prepared to be heat sensitive, usually the brain cells do not need specific treatment to sense the heat however in these engineered mice a virus was injected which carried the gene that is needed to prepare the heat sensitivity in the brain, now the neurons incorporate the gene in their genome and prepare the sensor. These engineered mice were injected with the nano iron spheres and magnetic field passed over them results in warming of the nano spheres which in turn is sensed by the heat sensitive neurons in the mice and then these fire.

These experiments are sort of remote brain control however researchers are working towards more innovative ways of using the nanotechnology into medicine in the near future. Therefore, nanotechnology truly seems to be the answer to cure most of the deadly diseases like cancer.
