Nano-biotechnology how far away from clinical clinics
Nano-biotechnology in clinical applications in the foreseeable future will be very extensive. Over the past 10 years, the use of nanotechnology for the early diagnosis and treatment of malignant tumors of exploration and research in the Western developed countries in full swing, the United States, Japan, Germany and other developed countries investing in the study, the aim of conquering cancer 15 years.
American Alfret A, C Douglas, and the use of nanoparticles <BR> drug and gene fragments with other drugs, a nano-microspheres, in animal experiments in the treatment of breast tumor targeting success. Nano-technology in recent years in the early diagnosis and treatment of malignant tumors of the most successful is the ferrite materials and nano-related technology. Wuhan University of Technology Li Shipu in vitro experiments in particle size found in 20-80 nm with hydroxyapatite nanomaterials kill cancer cells function. However, in full security, effective access to clinical application, such as the former are more reliable nanoparticle, more precise targeting substances, more effective medications, more sensitive, more convenient operational sensors, as well as in vivo mechanism of vector dynamic testing and analysis methods and other major issues pending study solution.
Overall, international nano-biotechnology research covers bio-nano-materials, drugs and transgenic nanoparticle, nanotechnology biocompatibility of artificial organs, nano-biosensors and imaging technology, the use of scanning probe microscopy, and DNA analysis of protein structure and function, and other important areas, Early diagnosis of diseases and enhance the effectiveness of the goal. In nano-biomaterials, particularly in the area of drug nanoparticle research has made some positive progress in cancer clinics nano biotechnology has also made progress in the experimental stage, other aspects of the research is still at the exploratory stage.
The small knowledge
Nanometer (nanometer, nm) is a length of flat, nanometer is a billionth of 10 meters, one thousandth micron, which is about three, four atoms width, the DNA chain is a nanometer in diameter around. As nanotechnology materials show different from the many special features of traditional materials, nano-technology were key to the 21st century as one of the high-tech.
