Tianjin University applies MEMS technology to break through the problem of introducing cells into the world
It was learned from Tianjin University that the micro-technical team of the School of Fine Instrumentation made an important breakthrough in the direction of cell-targeted drug introduction, and for the first time in the world, "Application of Micro-Electro-Mechanical System (MEMS) Thin-Film Resonator Excitation" Ultra-High Ultrasound (Gigahertz) 'A new technology for the introduction of targeted cell drugs," "surgery for cells."
The technology realizes the precise introduction of a variety of molecules to cells, and provides a new method for the traditional targeted drug introduction technology, expanding the application of MEMS technology in life sciences.
It is reported that the relevant research results of Tianjin University have recently been published online in the internationally authoritative academic journal "Small" in the field of micro-nano technology.
The accurate and efficient introduction of exogenous molecules such as target drug molecules, therapeutic genes and proteins into the interior of cells is an important technology in modern precision medicine and cell molecular biology research. Traditional cell introduction relies on chemical drugs or electrical stimulation, such as "chemotherapy", which not only fails to introduce selective drugs, but also causes "cell immune response", destroying healthy cells and causing large side effects. The micro-nano device has the advantages of small volume and low power consumption, and can be implanted into the body to realize selective cell drug introduction. The use of micro-nano technology to realize single-cell drug introduction has become a hot spot in modern molecular biology research.
Microelectromechanical systems (MEMS) are microelectromechanical systems consisting of movable elements ranging in size from 0.5 to 500 microns. The micro-technical team of Tianjin University, under the leadership of Prof. Pang Wei, a national expert of thousands of people, and the team members of the National Youth Thousand Experts, Professor Duan Xuexin and Associate Professor Wang Yanyan, carried out a large number of microelectromechanical resonators, sensors and actuators research and life. The extension of science and other fields has achieved a number of high-level scientific research results with independent intellectual property rights.
(1) Natural astaxanthin: it is a powerful antioxidant, known as the king of anti-aging. Its ability to scavenge free radicals is 6000 times that of vitamin C; 1000 times that of vitamin E; yes β- 100 times the efficacy of carotene; It is 20 times more effective than selenium; It is 700 times the efficacy of anthocyanins; It is 320 times the efficacy of tea polyphenols; It is 10 times more effective than lycopene; 800 times that of coenzyme Q10;: It is 240 times more effective than grape seed extract; It is 200 times the efficacy of carotol (Lutein); It is 3000 times higher than resveratrol[ 1]
(2) Vitamin C: also known as ascorbic acid, is an acidic polyhydroxy compound containing 6 carbon atoms: lack of vitamin C can greatly reduce endurance exercise ability. Vitamin C supplementation can significantly reduce exercise-induced oxidative stress. The safe dose of vitamin C supplementation is 0.5 ~ 3.0 g / day. The recommended daily dose of vitamin C supplement is 0.5 ~ 2.0 G.
(6) Anthocyanins: anthocyanins belong to biological flavonoids, and the most important physiological active functions of flavonoids are free radical scavenging ability and antioxidant ability.
(7) Tea polyphenols: tea polyphenols are all natural antioxidant foods extracted from tea. They have the characteristics of strong antioxidant capacity, non-toxic side effects and no peculiar smell. The antioxidant effect of tea polyphenols can eliminate reactive oxygen species and inhibit the consumption of vitamin C, so it can keep skin delicate and white.
