Micro/nanoscale tools for neurobiology

中国神经科学学会第四次会员代表大会暨第八届全国学术会议

＜正＞By combining an arsenal of micro/nanoscale tools including self-assembled monolayer,microcontact printing and microfluidics,we have been able to precisely pattern cells into virtually any geometry on two dimensional surfaces, from single cell to thousands of cells,from single type to multiple species,from cell lines to primary cells,and release them afterwards,***,we have patterned primary neurons and astrocytes and release them afterwards from their original *** patterns can be employed for constructing neural networks in ***,we have been able to reliably create spatial gradients of both soluble and surface-bound *** have devised a substratebound gradient of laminin for studying neuronal polarity,and revealed that laminin gradient orients axon specification. Besides,by creating a zebra-striped pattern of laminin with characteristic dimension of tens of micrometers onto which primary neurons are seeded,we have discovered that neuritogenesis favors the edges of the stripes which corresponds to steepest point of the gradient *** conclusion,by adapting these micro/nanoscale tools to specific problems,they hold promise for solving a range of issues in understanding the formation and function of the nervous system.

MICROSTRUCTURES AND PROPERTIES OF ELECTRONIC packaging BOX WITH HIGH SILICON ALUMINUM-BASE ALLOY BY SEMI-SOLID THIXOFORMING

亚洲精密工程、微纳技术国际会议

作者： Zhao Libo, Zhao Yulong, Jiang Zhuangde, Liu Xiue State Key Lab for Manufacturing Systems Engineering Shaanxi Province MEMS center Institute of Precision Engineering, school of Mechanical Engineering, Xi'an Jiaotong University Xi'an Jiaotong University Winner Instruments Co., LTD. Shaanxi, 710049,China

A high temperature lower range piezoresistive pressure microsensor based on the MEMS (Micro Electro-Mechanical System) and SIMOX (Separation by Implantation of Oxygen) technology has been developed for the harsh environment application. This piezoresistive pressure microsensor's sensitive chip is constituted by silicon substrate, a thin silicon dioxide layer by SIMOX, four Wheatstone bridge p-type resistances in the measuring circuit layer by boron ion implantation and photolithography, stress matching layer with silicon nitride, and beam lead layer (Ti-Pt-Au) for connecting p-type resistance by sputtering, and a cavity like cup structure fabricated by the wet etching. A special silicon dioxide layer is fabricated by the SIMOX technology in the sensitive element, which solves the problem of the leak-current influence, so the pressure microsensor fabricated by high temperature packaging process can be used in the fields with high temperature up to 200℃. In contrast, the traditional solid-state piezoresistive pressure chip is not able to used in high temperature fields, because the leak-current through the p-n junction which is used to isolate the upper measuring circuit layer from the silicon substrate, will increases at the temperature above 120℃, so the sensor's performance will be deteriorated under high temperature. Otherwise, some compensation methods have been studied, the thermal zero drift k0 and the thermal sensitivity ks of the pressure microsensor are easy to be less than 2×10-4FS/℃. In addition, this type pressure microsensor's range is up to 1MPa. The experimental results show that this pressure microsensor has good performances in the high temperature and is able to meet the requirements of the modern industry, such as aviation, wind tunnel, automobile industry, engine, etc.
