Application of 4556-23-4. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: Pyridine-4-thiol, is researched, Molecular C5H5NS, CAS is 4556-23-4, about Etchable SERS nanosensor for accurate pH and hydrogen peroxide sensing in living cells. Author is Bai, Lu; Wang, Xiaojie; Zhang, Kaifu; Tan, Xiaoyue; Zhang, Yuying; Xie, Wei.
No methodol. has been built to distinguish intracellular SERS nanosensors from cell outer membrane bound-ones. Here the authors propose a “”turning off”” strategy by combining etchable SERS nanosensors with a non-permeable etchant. The SERS signals outside the living cells can be rapidly removed, leaving only the internalized nanosensors for imaging and thereby allowing accurate intracellular pH and H2O2 sensing.
