Portable electrochemical impedance biosensing with DRT-enabled machine learning for detecting E. coli O157:H7 in poultry meat

confirmed applicability in a food-relevant matrix, along with high selectivity against non-target bacteria and stable performance during storage. This work is novel in combining DRT-based mechanistic feature extraction with ML-based inference to deliver a field-deployable immunosensing platform for robust pathogen quantification in complex food samples.
