Staphylococcus Enterotoxin B

In this paper, an aptasensor with high sensitivity and rapid response was developed for the detection of staphylococcus enterotoxin B (SEB) by using thiol-modified piezoresistive cantilever. Thiol-modified aptamers, acting as the functionalized sensing elements, were immobilized on the nanogold-coated surface of the sensing cantilever as agents for detecting SEB. By using the functionalized aptasensors, different concentrations of SEB were detected with a wide detection range of 6-100 ng/mL and a quick response in milk. The experimental results indicated that the cantilever-based aptasensors had sufficient sensitivity for the detection of SEB in real food commodities and might provide an economical platform for on-site detections of different toxicants with the advantages of portability, high sensitivity, and rapid response.

2,6-Diformyl-4-methylphenol fluorophore derived Schiff base sensors detect metal ions such as Zn2+, Al3+, Hg2+, Cd2+, Sn2+ and Cu2+ with high sensitivity and selectivity through changes in fluorescence intensity based on CHEF, ICT, FRET, ESIPT, C=N isomerization and PET mechanism. Several anions viz. HPO4 2–, H2PO4 –, PO4 3–, AsO3 3–, H2AsO4 –, AsO2 –, PPi (pyrophosphate), I–, F– and N3 – were also detected through intermolecular hydrogen bonding (between sensor and anion) based on TICT, PET, CHEF, ESIPT and aggregation induced emission mechanism. Selectivity and sensitivity for these metal ions and anions were achieved by introducing various amines to core fluorophore 2,6-diformyl-4-methylphenol. Majority of these fluorescent sensors were Zn2+ ion selective. Due to the filled d10 electronic configuration of Zn2+ ion usually does not show deactivation of excited state via any electron or energy transfer mechanisms. Both solvent dependent and independent ten multi-ion selective sensors are found. This review will consolidate on 2,6-diformyl-4-methylphenol derived Schiff base fluorescent chemosensors.
