Fluorescent siderophore pyoverdin (PVD) was produced from a soil isolate Pseudomonas monteilii strain MKP 213. The PVD was purified near to homogeneity and applied for the fluorescent chemosensing of various antibiotics in aqueous solution (pH=7.0).

- A new fluorescent receptor (receptor 3) was created to detect Cu(2+) and Zn(2+) ions selectively and sensitively in semi-aqueous environments.
- The presence of Zn(2+) and Cu(2+) notably increased and decreased the fluorescence of receptor 3, distinct from other ions.
- This receptor can form stable 1:1 complexes with Cu(2+) and Zn(2+), enabling its use as chemical inputs in a molecular level logic gate system.
A pyridine based imine-linked chemosensor has been synthesized and evaluated its binding affinity with library of transition metal ions. It has prominent selectivity towards Pb among other metal ions in DMF/HO (9:1, v/v) solvent system. The 1:1 stoichiometric was confirmed by job's plot and has a binding constant (K) = 5.

The compound 1 fluorometrically recognized Cu(2+) ion in CH3OH/H2O (90:10, v/v) by exhibiting an increase in emission upon complexation. In addition, Cu(2+) gave rise to a change in colour of the solution of compound 1, which was clearly visible to the naked eye under UV irradiation.
