TL;DR: A new fluorescent chemosensor that displays an excellent selectivity for pyrophosphate over adenosine triphosphate or phosphate in 100% aqueous solution is reported.
Abstract: We report a new fluorescent chemosensor that displays an excellent selectivity for pyrophosphate over adenosine triphosphate or phosphate in 100% aqueous solution. A unique fluorescent change was observed upon formation of a 2+2 excimer of the chemosensor.

TL;DR: A two-photon fluorescent off/on probe bearing imidazoline-2-thione as an OCl(-) recognition unit and triphenylphosphine as a mitochondrial-targeting group was synthesized and examined for its ability to image mitochondrial OCl (-) in situ.
Abstract: Hypochlorite (OCl–) plays a key role in the immune system and is involved in various diseases. Accordingly, direct detection of endogenous OCl– at the subcellular level is important for understanding inflammation and cellular apoptosis. In the current study, a two-photon fluorescent off/on probe (PNIS) bearing imidazoline-2-thione as an OCl– recognition unit and triphenylphosphine (TPP) as a mitochondrial-targeting group was synthesized and examined for its ability to image mitochondrial OCl– in situ. This probe, based on the specific reaction between imidazoline-2-thione and OCl–, displayed a selective fluorescent off/on response to OCl– with the various reactive oxygen species in a physiological medium. PNIS was successfully applied to image of endogenously produced mitochondrial OCl– in live RAW 264.7 cells via two-photon microscopy.

TL;DR: In this critical review, the fluorescent and colorimetric sensors are classified according to their receptors into several categories, including small molecule based sensors, calixarene based Chemosensors, BODIPY based chemosensor, polymer based chemOSensors), DNA functionalized sensing systems, protein based sensing systems and nanoparticle based sensing Systems.
Abstract: Exposure to even very low levels of lead, cadmium, and mercury ions is known to cause neurological, reproductive, cardiovascular, and developmental disorders, which are more serious problems for children particularly. Accordingly, great efforts have been devoted to the development of fluorescent and colorimetric sensors, which can selectively detect lead, cadmium, and mercury ions. In this critical review, the fluorescent and colorimetric sensors are classified according to their receptors into several categories, including small molecule based sensors, calixarene based chemosensors, BODIPY based chemosensors, polymer based chemosensors, DNA functionalized sensing systems, protein based sensing systems and nanoparticle based sensing systems (197 references).
