Harbin Institute of Technology made new progress in the field of microfluidics
Supported by the National Natural Science Foundation of China, Professor Han Xiaojun from Harbin Institute of Technology recently made a series of progress in the field of microfluidics. The study "Preparation of Yin and Yang Micromotors Based on Microfluidics and Their Applications in Release of Controlled Drugs" was published in "Small" (Impact Factor 8.368), "Microfluidic Controlled Topography O-phenylenediamine - silver nanoparticle complex "published in the cover of the paper in another area of ​​international chemical journal. Microfluidic technology is a rapid development in recent years, a technology that can be used in chip labs and chemical synthesis and other fields. The advantage is that the reaction conditions can be accurately controlled, the sample dosage is small. These two studies make full use of these features, by adjusting the sample injection speed, with block polymerization modified nanoparticles (including gold nanoparticles, gold nanorods and platinum nanoparticles, etc.) and o-phenylenediamine as the reactive element, preparation Half of the surface is a polymer, half the surface of the hollow nanoparticles of yin and yang hollow vesicles structure and morphology were spherical, spherical silver nanoparticles modified poly-o-phenylenediamine structure. For the metal nanoparticles containing yin and yang capsule structure of platinum particles can be used as a micro-motor, the speed of movement can be controlled by changing the concentration of hydrogen peroxide solution; and based on the extinction of gold nanorods absorb heat, the use of laser to achieve Controlled release of motorized drugs. Professor Han Xiaojun is director of Department of Biomolecular and Chemical Engineering, member of State Key Laboratory of Urban Water Resources and Water Environment. He has worked in the UK for many years and introduced talents to our school in 2009. He chaired 10 research projects including the National Natural Science Foundation of China and the New Century Excellent Talent Fund of the Ministry of Education. So far, he has published 69 SCI papers in a number of international authoritative publications .
