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.

      Scientists using carbon nanotubes(CNTs) and polymer film to develop new fabrics: can resist chemical and biological weapons       Scientists from Lawrence Livermore National Laboratory used carbon nanotubes and flexible polymer film to make synthesis of a breathable, lightweight fabric, wihch could help soldiers against the chemical and biological weapons.  A unique channel created by Carbon Nanotubes has achieved a good air permeability. Meanwhile, the density of the fabric, of which was only 5 nm pore diameter was quite high. It is understood that biological weaponsa such as viruses, usually it's bigger than 10 nm in size. In the experiment, the scientists confirmed that the new material is with the ability to repel dengue virus.  At the same time, to make the research results protects against chemical weapons also, scientists used some chemical-sensitive materials to improve carbon nanotubes, and ultimately achieved the goal.       Here sells purest and cheapest Carbon Nanotubes in the world. Carbon nanotubes is available with different purity grades and surface functionalization. Carbon Nanotubes is produced by Chemical Vapor Deposition (CVD) method by HW NANO and depending on the diameter one can obtain either single-walled Carbon Nanotubes(SWCNTs) ,double-walled carbon nanotubes (DWCNTs)or multi-walled Carbon Nanotubes (MWCNTs). Our current capacity for the production of MWCNTs far exceeds that of other suppliers.   Spec of carbon nanotubes:   1) SWCNT: diameter: 2nm, Length: short tube 1-2um and long tube 5-20um, purity: >91%,95%,99%   2) DWCNT: diameter: 2-5nm, Length: short tube 1-2um and long tube 5-20um, purity: >91%,95%,99%   3) MWCNT: diameter: 8-20nm,30-60nm,60-100nm, Length: short tube 1-2um and long tube 5-20um, purity: >99%   4) Low purity for the three ones above are all available.   5) Functionalized carbon nanotubes: COOH-CNTs, OH-CNTs, Amino-CNTs, Metal coated CNTs...   6) Dispersion: CNTs water dispersion, and CNTs oil dispersion.
