Sensitivity And Selectivity

A series of reaction-based probes have been developed by conjugation of maleimide–coumarin into ibrutinib. The resulting probes display high sensitivity and selectivity toward BTK, and were proven to be suitable for simultaneous protein labeling and no-wash imaging of BTK inside live mammalian cells.

Atp Sensing

: Adenosine 5'-triphosphate (ATP) plays a significant role in biological processes and the ATP level is closely associated with many diseases. In order to detect ATP in live cells, tissues and body fluids with a high sensitivity and selectivity, researchers have developed various sensing strategies. Particularly, owing to distinct physicochemical properties of nanomaterials and high sensitivity of fluorescence, a great deal of efforts have been devoted to developing nanomaterials-based approaches for fluorescent ATP sensing in recent years. In this review, we focus on the current development of nanomaterial-based fluorescent ATP sensors and discuss the sensing mechanisms in detail. The advantages and disadvantages of ATP sensing using different kinds of nanomaterials, including carbon nanomaterials, metal nanoparticles, semiconductor quantum dots, metal-organic frameworks and up-conversion nanoparticles have been thoroughly compared and discussed. Finally, current challenges and future prospects in this field are given.
