Abstract: In one aspect, a method of detecting a pathogen, e.g., Listeria bacterium, Chlamydia bacteria, gonorrhea bacteria and/or HPV, in a sample is disclosed, which comprises bringing a sample into contact with a graphene layer functionalized with an antibody exhibiting specific binding to the pathogen, monitoring electrical resistance of said antibody-functionalized graphene layer in response to interaction with said sample, and detecting presence of the pathogen in said sample by detecting a change in said electrical resistance indicative of interaction of the pathogen with said antibody-functionalized graphene layer. For example, a decrease of the electrical resistance of the graphene layer can indicate the presence of the pathogen in the sample under study. In some embodiments, a method according to the present teachings is capable of detecting pathogens, such as Listeria bacteria, Chlamydia bacteria, gonorrhea bacteria and HPV in a sample at a concentration as low as 4 cfu per 100 grams of a sample.

Abstract: The present teachings are generally directed to sensors that employ antibody- and/or aptamer-functionalized graphene layer (or graphene flakes and/or graphdiyne layer) for detecting a prostate-specific biomarker in a sample. A graphene layer can be deposited on a underlying substrate and functionalized with an antibody and/or aptamer that specifically binds with an analyte of interest (e.g., a prostate-specific biomarker). A sample under investigation can be introduced onto the functionalized graphene layer. The interaction of the analyte of interest, if present in the sample, with the functionalized graphene layer can mediate a change in at least one electrical property of the graphene layer, e.g., their DC electrical resistance. An analyzer can detect such a change and analyze it to determine whether the analyte is present in the sample. In some embodiments, calibration methods can be employed to quantify the analyte present in the sample.
