The nano-diamond is distinguished from other materials by virtue of excellent properties such as low toxicity, biocompatibility, larger specific surface area and the like, attracts the attention of many researchers, carries out deep research on the nano-diamond, carries out surface modification and modification on the nano-diamond, and further gradually carries out research combined with biomacromolecules.
Currently, nanodiamonds are widely used in the field of fine chemical engineering by virtue of their excellent physicochemical properties, and in particular, in skin care products, nanodiamonds are gradually used by researchers due to low toxicity and biocompatibility. Currently, there are hundreds of cosmetic products containing nanodiamond. However, as the research progresses, some problems are exposed, for example, the nano-diamond has a high specific surface energy, a large specific surface area, and is in a thermodynamically unstable state, and in addition, the surface activity of the nano-diamond is also large, and thus the agglomeration phenomenon between particles often occurs. Therefore, it is a major focus of current research on how to solve the agglomeration of the nano-diamond particles and effectively treat the surfaces of the nano-diamond particles to exert the excellent properties of the nano-diamond. Because the nano-diamond has incomparably excellent performances of other materials, the nano-diamond has a wide application prospect, particularly in the aspect of biomedicine, in recent years, the nano-diamond is considered to be a suitable carrier of a medicament for improving skin diseases, and various functional groups on the surface of the nano-diamond can be combined in a chemical bond mode for cancer diagnosis and treatment medicaments, and the nano-diamond becomes one of the main targets of the current cancer medicament research. In addition, the nano-diamond can improve the durability and stability of the drug and disperse the drug which is not dissolved in water. Also, since nanodiamonds have a large surface area, particles are loaded with a large amount of therapeutic agents, and thus, nanodiamonds are gradually applied to the field of fine chemical engineering, particularly in cosmetics and health products.
In the field of nano-diamond impregnated cosmetics, because of its good absorption properties, it can be formulated into a variety of skin care products, such as face washes, soaps, etc. There are now hundreds of cosmetic products on the market that contain nanodiamonds. Moreover, experiments show that the nano diamond can be combined with the skin surface, reduce the water loss in the skin, influence the functions of the water and lipid skin surface and protect the skin from aging. The nano-diamond has great potential in the aspect of ultraviolet protection, namely sunscreen cream due to unique optical properties. Therefore, nanodiamonds have been widely popular in cosmetics due to the properties of biocompatibility and low toxicity.
