An object that is only about one square centimeter and looks like a flat wafer. In fact, there are 1 million nano-doses made of diamond. These needles cannot be seen by the human eye because each needle is only 0.0074 mm long and the needle diameter is only about 135 nm, which is 0.000135 mm.
Diamond nanoneedle for treating skin diseases
These nanoneedle arrays were developed and pioneered by a team of scientists from the City University of Hong Kong. On August 5th, they explained the technology to the media in Hong Kong. Chen Xianfeng, one of the scientists who studied nanoneedle arrays, said that they used these needles to pierce the cell membrane, and then implanted genes and a series of biomolecules into cells to treat skin diseases. For example, in the medical profession, in the treatment of refractory skin diseases such as psoriasis and chloasma, a promising treatment is to implant genes into cells; and these extremely young nano-needles can serve as effective delivery roles, directly sending genes. Into the skin cells.
CVD diamond tools have longer life than single crystal diamond and PCD diamond tools in high-speed cutting. The CVD diamond produced by our company is translucent light yellow and is a pure diamond with a polycrystalline structure. Its physical and chemical properties are similar to those of natural diamond, and the welding and sharpening methods are basically the same as those of natural diamond.The CVD diamond produced is a pure diamond with a polycrystalline structure, the physical and chemical properties are similar to those of natural diamond, and the welding and sharpening methods are basically the same as those of natural diamond.
