An Electrochemical Nucleic Acid Biosensor for Triple-Negative Breast Cancer Biomarker Detection.

Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer, affecting younger women and women of minorities. The nomenclature "triple negative" is derived from the absence of the three most common breast cancer biomarkers: progesterone receptor (PR), estrogen receptor (ER), and human epidermal growth factor receptor 2 (HER2). It derives its name from testing negative for these three most common breast cancer biomarkers.

Foodborne pathogens are microbes present in food that cause serious illness when the contaminated food is consumed. Among these pathogens, is one of the most serious bacterial pathogens, and causes severe illness. The techniques currently used for detection are based on common molecular biology tools that are not easy to implement for field use in food production and distribution facilities.
