美开发出提高诊断能力的DNA计算机

 
 
作为第一种“中等-规模集成分子电路”，一种新型DNA-为基础的计算机是迄今为止同类型最强大的计算机，开发人员相信它能够导致更快、更准确地检测西尼罗河病毒和禽流感病毒，以及其他疾病。

该计算机叫做Maya-II(Molecular Array of Yes And logic gates)，其电路由DNA而不是硅组成。该系统是哥伦比亚大学医学院(New York, NY, USA)和新墨西哥大学(Albuquerque, NM, USA)的科研人员开发地。他们地研究成果发表于2006年11月《纳米通讯》(美国化学学会)。
 
DNA “Computer” May Lead to Better Diagnostics
 
Representing the first “medium-scale integrated molecular circuit,” a new DNA-based computer is the most powerful computing device of its type to date, and the developers believe it could lead to faster, more accurate tests for diagnosing West Nile virus and avian flu, as well as other diseases.

Called Maya-II (Molecular Array of Yes And logic gates), the computer’s circuits consist of DNA instead of silicon. The system was developed by a team of scientists at Columbia University Medical School (New York, NY, USA) and the University of New Mexico (Albuquerque, NM, USA). Their work was reported in the November 2006 issue of Nano Letters (American Chemical Society).
