Zinc Oxide nanowires/ZnO NWs, as an ideal material for the preparation of a Schottky contact type devices. Hongwu nanometer is professional manufacturer, supplier and exporter in china for nano materials in china. Our ZNO zinc oxide nanowires specification as follows: 1. D<100nm,L>5um,99.9%                2. D:100-200nm,L>1um,99.9%                          As nucleic acid detection is more and more widely applied to genotyping technology, clinical diagnostics and biomedical research and other fields, the traditional optical detection and real-time PCR technology have some disadvantages, such as high cost, no longer can meet the demand that the devices require the testing with high cost-effective, high speed and high sensitivity. By contrast, the one-dimensional material represented by the unmarked detection device, because of a high specific surface area, can offer the possibility for low-cost, simple and effective DNA testing. FET based on semiconductor nanowires is such a great potential device. Wherein, changing the metal - semiconductor interface of Schottky barrier height(SBH)can modulate device performance, which is a hotspot for researchers.        Zinc Oxide nanowires/ZnO NWs with excellent semiconductor and piezoelectric performance, is an ideal material for the preparation of a Schottky contact type devices. Researchers of the National Center for Nanoscience and other institutions made use of exerting external strains on Zinc Oxide nanowires to produce piezoelectric potential. Then on the basis of piezoelectric effect, the potential can be increased or decreased the effect of SBH link interface the carrier transportation, so that change the properties of nanowire-based devices. In addition, making specific hybridization between probe complementary target cDNA and nanowire adsorbed single-stranded DNA (the ssDNA), the device can achieve selective detection function.       The experimental results of this work showed that, when the compressive strain applied to the Zinc Oxide nanowire-based DNA sensor became -0.59%, the relative value of the current response increased by 454%. This fully illustrated that the modified method using a piezoelectric device electronics effect can significantly improve the detection performance of the Schottky contact type ZnO nanowire based DNA sensor.

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.
