Nanotechnology and applications

Not only helps prevent and treat plant diseases, nanomaterials can also save lives from some cancers, improve health.

"Nanotechnology can change the whole world, no country is not interested in this area because of its applicability in most social life. The problem is how to choose the path to suit this. and demand " , Professor Nguyen Hoang Luong, Hanoi Natural University emphasized at the conference " Nanotechnology and applications in medicine and pharmacy " organized by the Ministry of Science and Technology on July 19.

According to Professor Luong, in Vietnam, this advanced technology is increasingly invested, the scientific community has had many researches and applications such as kit to detect dome cancer; Quick test strips detect rotavirus causing diarrhea in children, DNA extraction for diagnosis.

Not only Professor Luong, most scientists appreciate the role of nanomaterials , especially agriculture and medicine . In agriculture, according to Mr. Nguyen Hoang Nam, Hanoi Natural University, nano silver and copper have the ability to disinfect, disinfect, and help plant photosynthesis well; Nano carbon increases plant growth. Nano silver bath for shrimp, nano-calcium, zinc is used as micro-fertilizers and animal feed.

In medicine and pharmacy, Vietnam is aiming to use nanotechnology in bio-marking, cell extraction, thermogenesis of cancer cells, drug injection. "Silver Nano for antiseptic and an alternative to antibiotics. It is also used in medical dressings and is capable of stimulating premature skin growth in burns and wounds. While nano calcium, zinc helping the body more easily absorb substances into the stomach and nano cucumin is anti-cancer and intestinal disease " , Mr. Nam cited.

At the seminar, one of the nano-applications researches attracted the attention of the scientific community is the study of quick test strips to detect children with diarrhea diarrhea virus, Hanoi University of Technology. Truong Quoc Phong said that the team developed a quick test of rotavirus from stool samples based on the principle of immune chromatography. The 30mm gold nanoparticle is made to function on the surface with a molecular layer. The scientists attached covalent anti-rotavirus antibodies to gold nanoparticles in the right conditions. The components of the test strip include a composite piece, a absorbent piece .

"The device was created with the ability to detect rotavirus in simple specimens, low threshold with analysis time less than 10 minutes and high accuracy. This success contributes to localization of products with cost lower than foreign products, " Phong said.
