2. Optical tweezers and their applications in biology: I have been engaged in the research of laser devices, the interaction between laser and atoms and molecules, nonlinear optics, photon localization, photonic crystals, optical tweezers and so on. He has published more than 100 articles in domestic and foreign magazines.
Current research topics and prospects: The current research projects include: sub-projects of the National "973" Project "Study on Physical Properties of Aperiodic Photonic Band Gap Materials" and "Development of Double Optical Clamp System and Its Application in Mechanical Measurement of Cytoskeleton protein". This paper mainly studies the characteristics of photonic crystals and optical tweezers, including the fabrication of two-dimensional photonic crystals in visible light and near infrared, the design, fabrication and characteristic measurement of new photonic devices based on photonic crystals; Nonlinear optical effect of nonlinear photonic crystals and its influence on photonic band structure: photonic band and light propagation characteristics in two-dimensional amorphous and quasicrystal photonic crystals: accurate measurement of mechanical properties of double optical tweezers system and cell membrane. In terms of photonic crystals, we will make full use of the existing micromachining conditions to develop photonic crystal devices that can be used to integrate optical paths; In the aspect of optical tweezers, the measurement of the interaction between different protein and the polymerization and depolymerization mechanism of microtubules in cytoskeleton are mainly studied. I hope to carry out more in-depth work in these international frontier fields.
He has served as visiting professor of pathology at Preston University, vice chairman of Jiangsu Pathology Society, chairman of Nanjing Pathology Society, editorial board member and editorial consultant of Chinese chinese journal of clinical and experimental pathology, convener of pathological gastritis group of National Gastric Cancer Research Association, and convener of gastric cancer pathology group in East China. Enjoy the special government allowance of the State Council. More than 90 clinicians and pathologists have been trained, and most of them have become academic leaders in their units. He has taught pathology for 25 years and 15 years in the annual digestive and respiratory clinical refresher courses entrusted by the Ministry of Health and the Provincial Health Department respectively. Taught twice the pathology of the national legionnaires' disease specialized course. Presided over Jiangsu 1 1 urban perinatal death investigation pathology part, won the second prize of the Ministry of Health's scientific and technological achievement award. Participated in compiling the first monograph on pathology of gastric and duodenal mucosa biopsy in China. In recent years, he participated in compiling Modern Pulmonary Diffuse Diseases edited by Hou Jie (published by People's Military Medical Press) and Digestive Diseases Volume edited by Xu (published by Liaoning Science and Technology Press). These two books were published in 2003 and 2005 respectively. To undertake part of the teaching tasks of national digestive and respiratory pathology courses 10 times; Translation of duodenal pathology and small intestine pathology. He published 62 papers including "The First Case of Diffuse Pulmonary Interstitial Fibrosis in China" and went to Nagoya for academic exchange and attended the Beijing International Cancer Conference. He won 9 provincial and municipal scientific and technological achievement awards, 2 military medals of the Korean People's Army, Class II 1 time of the China People's Liberation Army and Class III for 4 times, and was awarded the title of advanced worker of the city for 4 times. He was a member of Nanjing CPPCC twice.
