“…The sensor has the potential to provide a simple, affordable, portable, smartphone-assisted digital image colorimetry for the sensitive and selective measurement of glucose in human blood samples. Santos and colleagues 122 illustrated a smartphone-based colorimetric portable sensor based on AuNPs-PVA decorated with methyl orange (MO) azo dye (AuNP@PVA@MO) for the determination of H 2 O 2 . Herein, chemometric modelling makes it possible to visually detect H 2 O 2 with a detection limit of 1.70 mM, encouraging the use of nanomaterial sensors and chemometric techniques for sensor design and measurement.…”
