Nanoscale zinc oxide used to detect anthrax.(NANOTECHNOLOGY)
Advanced Ceramics Report, August, 2006
Zinc oxide (ZnO) nanomaterials are being investigated by scientists at Pennsylvania State University (Penn State), USA, as signal enhancing materials in highly sensitive deoxyribonucleic acid (DNA) sensor arrays.
The researchers report that the ZnO structures can successfully discriminate the DNA sequence of biological threats such as the bacteria Bacillus anthracis from other genetically related species.
In the research studies, Professor Jong-in Hahm from the Department of Chemical Engineering, together with co-researchers Nitin Kumar and Adam Dorfman, explored both covalent and non-covalent linking schemes in order to couple probe DNA strands to the zinc oxide nanostructures.
The researchers found that the use of ZnO nanomaterials enhances...
