Low-cost nanobiosensor to detect foodborne pathogen that causes listeriosis
(Nanowerk News) The foodborne bacteria Listeria monocytogenes sickens about 2,500 people in the U.S. each year and many more worldwide, killing about 25-30% of those infected. Listeriosis is caused by eating food contaminated with L. monocytogenes, and current methods for detecting the bacteria are costly and time consuming. An innovative nanotechnology-based method for developing an inexpensive biosensor to detect the pathogen in food is described in Industrial Biotechnology, a peer-reviewed journal from Mary Ann Liebert Inc., publishers (http://www.liebertpub.com). The articles are available free on the Industrial Biotechnology website.
The article is part of an IB Special Section on Nanobiotechnology, Part 2, led by Co-Guest Editors Norman Scott, PhD, Professor, Cornell University (Ithaca, NY) and Hongda Chen, PhD, National Program Leader, National Institute of Food and Agriculture, USDA (Washington, DC). In their Overview article "Nanoscale Science and Engineering for Agriculture and Food Systems", they describe the emerging opportunities and challenges for nanotechnology and nanomaterials research in industrial biotechnology.
"Nanoscale science continues to play a major role in catalyzing biotechnology innovation, yielding a broad spectrum of devices and products that are addressing many pressing social needs," says Larry Walker, PhD, Co-Editor-in-Chief and Professor, Biological & Environmental Engineering, Cornell University, Ithaca, NY.
