科内尔大学的研究生BRobIlic和物理学教授HaroldGCraighead及合作者共同开发出一个可以用来称量渺克(1 0 -1 8)数量级物质的纳米尺寸硅悬臂“天平”。这个悬臂是利用标准的平板印刷技术制作的,当用一束激光进行照射时它就会震荡。当分子或是颗粒吸附到硅的表面上时,可以通过监 Cornell graduate student BRobIlic and physics professor HaroldG Craighead and collaborators developed a nano-scale silicon cantilever “balance” that can be used to weigh orders of magnitude (1 0 -1 8). The cantilever is made using standard lithography, and it oscillates when irradiated with a laser beam. When molecules or particles are adsorbed onto the surface of silicon, they can be monitored
