Summary: A probe-free electrochemical immunosensor based on a Cu-MOF-carboxylated graphene oxide (COOH-GO) platform was developed for methyl jasmonate (MeJA) detection. The sensor utilizes Cu2+ in Cu-MOFs to provide redox signals, eliminating the need for an external redox probe. The COOH-GO improves structural stability and increases binding sites for MeJA antibodies. The immunosensor has a wide linear range, low detection limit, and potential for on-site applications in precision agriculture.

Summary: In pharmacological, environmental, biological, and material research, the design and synthesis of new fluorescence chemosensors based on Schiff base derivatives are crucial. A novel Schiff base compound (L) based on 2,4-dinitrophenyl hydrazine was designed and characterized for the selective detection of Zn2+, Cd2+ and Hg2+ ions. Probe L showed weak fluorescence emission in DMSO-H2O (10:90, v/v) due to isomerization of the C--N bond and photoinduced electron transfer processes, but it exhibited enhanced fluorescence emission upon addition of Zn2+, Cd2+, and Hg2+ ions, making it a unique chemosensor for these ions.
