Magnesium Oxide nano particles antibacterial 30-50nm         Magnesium Oxide nano particle(MGO) with a wide band-gap is an important inorganic material. MgO nano powder is a promising antibacterial agent because of its high resistance to harsh environment.  For the antibacterial ablity of MgO nano powder is related to the particle size. The antibacterial activity was increased with the decrease of the particle size of MgO nano. For particles in the size range 50-70 nm, the bactericidal efficacy of nano-MgO increased slowly with decreasing particle size. When the size under 40 nm, the bactericidal efficacy of MgO nano increases a lot and could kill more bacteria. This proves that the particle size is smaller the antibacterial efficacy of MgO is stronger. MgO nano particles penetrated the bacterial cell wall and cell membrane. For the size is smaller, and then killed more bacteria. Also MgO nano particles with large specific surface area increase as the size of the nano particles decreases. For the large surface area with lots of reactive groups on the particle surface and high antibacterial activity will be obvious.       Hongwu International Group Ltd is committed to provide high-quality Magnesium Oxide nano particles(30-50nm, 99.9%) with the most reasonable price for customers who are doing nanotech research and have formed a complete cycle of researching, manufacturing, marketing and after-sale servicing. Our products have been sold to many countries around the world.

Silver nanoparticles are well known for their antimicrobial properties. It can be used as an antibacterial and disinfectant. Addition of very small amounts of silver nanopowder (~0,1%) into different inorganic matrises makes those materials effective for killing pathogenic microorganisms like Escherichia Coli, Staphylococcus Aurous, etc. In addition to the silver colloids, there are nano silver powders to supply. Our packing is as follows:
