Nano-particle enhanced impedimetric biosensor for detedtion of foodborne pathogens

Molecular approaches for detection and identification of foodborne pathogens

Foodborne pathogens comprise microorganisms such as viruses, bacteria and parasites that can be transmitted by food and affect public health worldwide. The most common viruses transmitted via food are hepatitis A virus and Norwalk-like caliciviruses. Also, the most common bacteria involved in foodborne illnesses are Campylobacter jejuni, Clostridium perfringens, Salmonella spp, Escherichia...

Detection of Foodborne Pathogens

ments, food-producing companies, the agricultural sector, consumer organizations and four federal departments that share responsibility for food safety, i.e. Health Canada (HC), the Public Health Agency of Canada (PHAC), the Canadian Food Inspection Agency (CFIA), and Agriculture and Agri-Food Canada (AAFC) (Figure ). Part of the responsibility of the AAFC is to develop food-safety programs tha...

Potentiometric, Amperometric, and Impedimetric CMOS Biosensor Array

Impedimetric biosensor for early detection of cervical cancer.

An impedimetric biosensor based on PEGylated arginine functionalized magnetic nanoparticles for early detection of cervical cancer is reported. The cervical cancer cells could be selectively and sensitively detected down to 10 cells mL(-1) on the modified electrode, which is promising for advancement in clinical diagnosis and monitoring of tumors.

Real-Time Biosensor Platform: Fully Integrated Device for Impedimetric Assays

An impedimetric biosensor platform for bio-affinity assays was developed based on real-time, label-free electrochemical detection performed via direct interface to electronic digital data processing. The sensor array consists of 15 gold microelectrode pairs enclosed in three reaction chambers and bio-functionalized with specific DNA probes. The impedance change caused by specific target analyte...
