What is the golden nanoparticles?
Gold nanoparticles, also known as colloidal gold, is a particle of a submicrometer made of gold. These nanoparticles, usually spherical or bars of a similar shape, can be used in fields of medical and electron microscopy to help detect or destroy cancer, or help in marking with microscopic experiments. To create a golden nanoparticles, gold ions turn into neutral atoms and the mixture is added to the ions citrate. Golden nanoparticles are most often formed in liquid solution and can be easily detected by laser. Unlike the glossy color of gold, the nanoparticles are dark red. After removing the surcharge, it is added to the liquid solution and the citrate ions are also added to the separation of gold to nanoparticles. The scientist will know that gold is separated when it becomes dark red. If atoms are not nanoparticles, but slightly larger, then the solution appears as dark yellow.
in the area of cancer detectionY and electron microscopy is of great importance. When it is done without nanoparticles, searching for the area can be blindly difficult and the observer can omit the object for which he looks. If gold nanoparticles are added to the area, it will create a stain of species from which light can bounce. The light reflex makes it easier for observers to find cancer cells or mark other parts by attaching gold to an antibody or lectin. It is also cheaper than the use of florescent dyes to find cancer and tends to be more effective.
In addition to helping medical cancer experts, the solution of gold nanoparticles is also useful in the treatment of cancer. If cancer is in an area where a laser can penetrate, the golden end of the laser helps to destroy cancer cells. If the laser cannot penetrate into the area, it has been shown that the injection gold nanoparticles into cancer prevents the reproduction of cancer and eventually kills it.
Further use of golden nanoparticles in the medical industry is J JAKO drug carrier. Some medicines receive interference from the mononuclear phagocyte system, part of the immune system. Each gold -gold nanoparticles are so small that they can normally do around this system and supply medicines to the body.
