A facile, highly sensitive “turn on” SERS nanosensor for the detection of glucose in urine has been developed based on the aggregation of the 4-mercaptophenylboronic acid decorated silver nanoparticles in the specific bonding to glucose.
A turn-on fluorescent sensor of hydrogen peroxide and glucose was developed based on a label-free nanozyme MIL-53(Fe) without other chromogenic reagents.
