On the afternoon of May 23 and May 24, 2018, the 46th "Academic Lecture of Department of Precision Instrument" was successfully held in room 4302 and 4304 of Building 9003. Professor Jole. Voldman, from Electrical Engineering and Computer Science of MIT, was invited to give an academic lecture entitled "Bioelectronic Measurements". The lecture was hosted by Associate Professor Wang Wenhui from Department of Precision Instrument.

The first part of the lecture focused on microfluidic cell manipulation tools based on intrinsic properties of cells. Microsystems provide new methods to control cells. Professor Voldman introduced relevant applications, namely, equidielectric separation method, which uses electric field to drive cells to the dielectric constant gradient, so as to make cells electro-transparent. This method can quickly analyze the immune cell driving mechanism and play a great role in the control of inflammation and other immune disorders. The second part focused on microscale cellular and environmental manipulation for basic cell biology. Professor Voldman introduced two complementary approaches to realize the generation of cellular pairs. These two methods can realize the pairing of immune cells, and more effective way to study the relevant immune mechanism. For environmental manipulation, fluid flow is used to create convection-dominant transmission environment, so that information transmission among cells can be controlled. The two parts of the lecture aroused great interest and wide discussion among teachers and students. In the end, Professor Voldman answered the questions meticulous.

Professor Voldman works on microfluidics technologies in bio-medicine, particularly in cell classification and stem cell biology. He has developed many techniques for sequencing, cultureing and classifying various cell types, including immune cells, endothelial cells and stem cells. His current research includes summarizing atherosclerosis conduction in microfluidic chips and using microfluidic tools to study how immune cells attack cancer cells. His research results have been recognized by important research institutions and societies, and he has won many important young scholar awards.

“Academic Lecture of Department of Precision Instrument” is a series of high-level academic lectures and activities in which our department is focusing on inviting famous scholars at home and abroad to give academic reports, develop academic views of teachers and students, promotes interdisciplinary and academic exchanges, and stimulates and enhances students’ interest and potential of academic research and motivate them to follow the road of academic research unswervingly and advance fearlessly.
