Biosensors show promise, but their performance is often demonstrated in model samples using non-native pathogens and has never been studied towards S. aureus detection in naturally contaminated samples. This study addresses the gap by directly comparing results taken with a novel piezoelectric biosensor, capable of one-step detection, with four conventional cultivation-based methods. Our findings reveal that this biosensor, based on an antifouling nanolayer-coated biochip, exhibits exceptional resistance to biofouling from unprocessed dairy products and is further capable of specific S. aureus detection. Notably, it performed comparably to Petrifilm and Baird-Parker methods but delivered results in only 30 min, bringing a substantial reduction from the 24 h required by cultivation-based techniques.
