Conventional bacteria detection from wound infections requires costly or time-consuming methods that require either trained personnel, tedious sample preparation, or complex instrumentation. Hence, it is crucial to develop simple and inexpensive methods that enable accurate, point-of-care assessment of wound infections. Herein, we developed a Paper sensor to detect metabolites, i.e. heterocyclic Amine/Carbonyl, Lactate, Moisture, Trimethylamine and Tryptophan derivatives (termed PALM-T
