LLNL开发的纳米导线系统能够检测生物战制剂

 
 
一种以新型条形码为基础的生物探测纳米导线能够在野外检测生物战药物。该系统还能够检测感染性疾病爆发的受害者。

Lawrence Livermore国家实验室(LLNL, Livermore, CA, USA)的研究人员建立不同金属层的亚微米检测仪，包括金、银和镍等能够作为“条形码”检测不同抗原和毒素，包括炭疽、天花、蓖麻毒素和肉毒杆菌。这些研究人员是由LLNL的生物安全和纳米科学实验室的Jeffrey Tok领导的。该系统在2006年8月4日《Angewandte Chemie》期刊在线国际版上进行了介绍。

The team, which included researchers from Stanford University (Stanford, CA, USA), the University of California-Davis Center for Biophotonics (Sacramento, CA, USA), and Nanoplex Technologies (Mountain View, CA, USA), used the multi-striped metallic nanowires in a suspended format to rapidly identify sensitive single and multiplex immunoassays that simulated biowarfare agents. They produced nanoscale wires by electrochemically depositing metals within the tiny cavities of porous mineral solids.
 
Nanowire System Detects Biowarfare Agents
 
A new barcode system based on biosensing nanowires can help to detect biowarfare agents in the field. The system can also be used to detect victims of an infectious disease outbreak.

Lawrence Livermore National Laboratory (LLNL, Livermore, CA, USA) researchers built submicrometer layers of different metals including gold, silver and nickel that act as “barcodes” for detecting a variety of pathogens and toxins including anthrax, smallpox, ricin, and botulinum. The researchers were led by Dr. Jeffrey Tok of LLNL’s biosecurity and nanosciences laboratory. The system was described in the August 4, 2006, online international journal Angewandte Chemie.
