Nanotechnology has been successfully applied in China's medical field. A group in Nanjing used  nano silver  technology to develop and produce a medical dressing, a long-acting broad-spectrum antibacterial cotton. The production principle of this antibacterial cotton is to make silver into 20 nanometer ultrafine particles through nanotechnology, and then attach it to cotton fabric. Silver has the effect of preventing ulcers and accelerating wound healing. After the nanotechnology treatment, the surface of silver increases sharply, the surface structure changes, and the sterilization ability increases by about 200 times. It has a good inhibitory effect on clinical common surgical infections. Nanoparticles and nanoparticles are used as drug delivery systems. The basic properties of the materials they produce are non-toxic, stable, good biological properties, and do not chemically react with drugs. Nanosystems are mainly used for the administration of drugs with high toxicity, sh...

If Australian e-cigarette users are celebrating tonight, we should understand them! After all, a ban on nicotine imports, which will take effect on July 1, was suddenly withdrawn by Australian Health Minister Greg Hunt, and was postponed until January 1, 2021. The ban was announced on June 20. The ban shows that from July 1, the import nicotine e-liquid will be banned, and anyone who violates the regulations will be fined $220,000. But e-cigarette users can still obtain nicotine e-liquid through a doctor's prescription. However, according to local media reports, the sad reality is that very few Australian doctors are willing to write nicotine prescriptions under the current law, and given the complex and time-consuming requirements of the new plan, there are even fewer people now willing. After the ban was announced, the Australian Health Minister felt protests and opposition from local e-cigarette users. Angry opponents entered social media and called and wrote to local officia...
