Label-free, rapid Listeria monocytogenes biosensor based on a stimulus response nanobrush and nanometal hybrid electrode

Althawab S., Oliveira D.A., Smith C., McLamore E.S., Gomes C., Texas A&M University, US

Recent foodborne outbreaks have heightened public concern about food safety and created a greater impetus to improve methods for foodborne pathogen detection. The most prevalent foodborne pathogens that persistently cause infections include Salmonella Typhimurium, Listeria [...]

Antibody Immobilization on Conductive Polymer Coated Nonwoven Fibers for Biosensors

McGraw S.K., Alocilja E.C., Senecal A.G., Senecal K.J., Prata G.N., Senecal A.G., Senecal K.J., Michigan State University, US

Research is being performed to develop rapid and novel electrochemical biosensors for the detection of food pathogens at the US Army NSRDEC. The focus of the research is fiber based platforms to perform both capture [...]

Development of SERS Spectroscopy for Routine and Rapid Identification of Escherichia Coli and Listeria Monocytogenes on Ag Colloidal Nanoparticles

Chen Y-R, Liu Y., Nou X., Chao K., USDA/ARS Beltsville Agricultural Research Center, US

Rapid, accurate, and preferably routine methods for the identification of foodborne bacteria are increasingly important, because of bio- /agro-terrorism threats, public health concerns, and economic loss. Conventional detection of bacteria is time-consuming, requiring 5-7 days, [...]
