康乃尔大学的研究人员通过纳米制造技术和生物学结合 ,已发明一种能揭示潜在有害细菌存在的带有抗体组成衍射光栅的硅芯片。应用和工程物理学教授 H.Craighead和食品科学教授 C.Batt用微接触印刷工艺把抗体图样印制到硅上 ,因此简化了生产过程。通过把大肠杆菌细胞俘获到光栅线 Researchers at Cornell University have invented a silicon chip with an antibody-composition diffraction grating that reveals the presence of potentially harmful bacteria through a combination of nanotechnology and biology. H. Craighead, professor of applied and engineering physics and C.Batt, a professor of food science, have printed the antibody pattern onto silicon using the microcontact printing process, thus simplifying the manufacturing process.
