Efficient fluorescent ATP-sensing based on coordination chemistry under aqueous neutral conditions

Delivery modulation in silica mesoporous supports via functionalization in the pore outlets with a Zn(II)–bis(2-pyridylmethyl)amine complex

“…In fact the interaction of Zn(II)-dipicolylamine complexes with both organic and inorganic phosphates is well documented and for instance has been extensively used for the preparation of selective fluorogenic probes for these anions. [68][69][70][71][72][73][74][75][76][77] Moreover, in order to test the effect of the concentration of the anions on the [Ru(bipy) 3 ] 2+ dye release behavior of the SZn material additional experiments were carried out using anions at a concentration of 1.0 x 10 -2 mol L -1 . In this case nearly the same inhibition trend for solid SZn was observed (vide infra).…”

“…In fact phosphate has been reported to display a high affinity for Zn(II)-3-like complexes. [68][69][70][71][72][73][74][75][76][77] Moreover the effect of the anion size (and charge, vide infra) can be observed when the anion series phosphate, pyrophosphate, AMP, ADP or ATP is compared. In this case all these anions have been reported to form complexes with Zn(II)-3-like complexes and the different cargo release is related with their different size; i.e.…”

A Ga3+self-assembled fluorescent probe for ATP imaging in vivo

“…Accordingly, considerable efforts have been devoted to develop fluorescent sensors for ATP (Ojida et al, 2002(Ojida et al, , 2006(Ojida et al, , 2008Weitz et al, 2012;Xu et al, 2009Xu et al, , 2011Li et al, 2014;Rao et al, 2012;Strianese et al, 2012;Moro et al, 2010;Shi et al, 2013;Zhang et al, 2013aZhang et al, , 2013bNgo et al, 2012;Zhao et al, 2012;Schäferling and Wolfbeis, 2007). Hamachi and co-workers reported a zinc dipicolyl-tethered xanthenes (Ojida et al, 2008), acridine (Ojida et al, 2006), or anthracene (Ojida et al, 2002) as turn-on type fluorescent sensors for ATP. Weitz et al (2012) presented a time-gate luminescent probe for ATP at neutral pH.…”

“…Among of them, metal-assisted sensors possess excellent affinity for phosphates, which is conducive to ATP binding recognition in complex milieus (O'Neil and Smith, 2006). Zn-pyridine complex receptors are most often used in recent years (Ojida et al, 2002(Ojida et al, , 2006(Ojida et al, , 2008Rao et al, 2012;Strianese et al, 2012;Moro et al, 2010;Shi et al, 2013;Zhang et al, 2013aZhang et al, , 2013bNgo et al, 2012). However, these mono-or dinuclear Zn-pyridine complexes need tedious synthetic procedure to link receptors with fluorophore.…”

Enzyme-based Field-Effect Transistor for Adenosine Triphosphate (ATP) Sensing

“…14,15 A contrived molecular system is probably required to derive of an in situ assay for ATP monitoring. In these respects, the enzyme apyrase (ATP dihydrolyrase: E.C.…”
