A fluorescent naphthalimide chemosensor for ATP bearing a dipicolylamine group complexed with a Zn(ii) metal as a receptor moiety was synthesized and its sensing properties regarding ATP and other related phosphate species were evaluated.

The design of two-dyed fluorescent silica nanoparticles for ATP detection is presented. The indicator dye possesses a dipicolyl-amine (DPA) unit complexed with Zn(ii) as a receptor function for ATP while a rhodamine derivative is used as the reference dye. The nanoparticles were fully characterized regarding analytical performance, morphology and cytocompatibility.

A polymeric ratiometric fluorescent sensor for Zn(II) has been developed based on a Zn(II) responsive naphthalimide fluorophore (λEM 535 nm) and a Zn(II) insensitive rhodamine calibration fluorophore (λEM 579 nm) both coupled to a common poly(allyl amine) backbone. A concentration dependent increase in the ratiometric response (I 535 nm/I579 nm) was observed in the 0-25 mM Zn(II) ion range for the sensor in aqueous buffer. The effect of dilution on the ratiometric intensity of the polymeric sensor was also studied and no change in ratiometric response was observed upon dilution to 50% of its original concentration. In contrast, when the polymeric sensor was incorporated within a Gantrez AN-139 hydrogel matrix, a linear ratiometric response was observed upon addition of increasing amounts of Zn(II) to the gel. Therefore, this approach offers the opportunity to determine Zn(II) concentration in environments where sensor concentration may vary dramatically. the Partner Organisations 2014.
