A new naphthalimide-based fluorescentprobe for the detection of hydrogensulfide has been designed and developed. The probe exhibits high selectivity and sensitivity, with efficient colorimetric and ratiometric response for H2S under mild conditions. Furthermore, the probe was successfully used for fluorescence imaging of H2S in livingcells.

Beta-lactam compounds to detect carbapenemases or microbial carbapenem resistance are disclosed. The compounds contain a chemical probe. Upon hydrolysis by carbapenemases, the compounds undergo intramolecular rearrangement and release the chemical probe. Detection of the released chemical probe indicates the presence of carbapenemases and the presence of microbial carbapenem resistance.
