In the emerging field of medical image processing, computer vision, pattern recognition and other digital signal processing applications, window technique is vastly used. A window function is a mathematical function that is zero-valued outside of some chosen interval. When another function is multiplied by a window function, the product is also zero-valued… (More)
The binding behavior of triphenylene based copper ensemble prepared in situ has been investigated toward various anions (F(-), Cl(-), Br(-), I(-), CH(3)COO(-), H(2)PO(4)(-), NO(3)(-), OH(-), ClO(4)(-), CN(-), CO(3)(-) and SO(4)(-)) by UV-vis and fluorescence spectroscopy. Among various anions tested, 1-Cu(2+) ensemble shows selective and sensitive response… (More)
We report a two-photon fluorescent probe for ratiometric imaging of cysteamine in situ. This probe can detect the levels of endogenous cysteamine with statistical significance in live cells and brain hippocampal tissues, revealing that cysteamine is localized mainly in the perikaria of the pyramidal neurons and the granule cells.
Supramolecular aggregates of hexaphenylbenzene derivative exhibit aggregation induced emission enhancement and modulation of self-assembled architecture from spherical to flower-like assembly in the presence of H2S. Furthermore, probe displays higher photostability, low toxicity and bright green fluorescence in two-photon microscopy (TPM) imaging for the… (More)
