Binding of a potent anticancer agent, ponatinib (PTB) to human serum albumin (HSA), main ligand transporter in blood plasma was analyzed with several spectral techniques such as fluorescence, absorption and circular dichroism along with molecular docking studies. Decrease in the KSV value with increasing temperature pointed towards PTB-induced quen...

A ratiometric fluorometric assay for mercury(II) ion is described. It is making use of glutathione-stabilized gold nanoclusters (GSH-AuNCs) modified with tetraphenylporphyrin tetrasulfonic acid (TPPS). The resultant GSH-AuNC/TPPS nanocomposite displays dual emission (at 572 and 664 nm) under a single excitation wavelength of 365 nm. Mercury(II) ion...

For TNP chemosensor 2-(4,5-Bis(4-Chlorophenyl)-1H-Imidazol-2-yl)-4-Chlorolphenol (HPICI), previous thought with no theoretical basis was that excited-state intramolecular proton transfer (ESIPT) process and the ground-state HPICI-TNP complex are mainly responsible for its fluorescence emission and the detection of TNP. However, this interpretation ...

A turn-on fluorescent sulfide probe was prepared from carbon dots (CDs; synthesized using an environmentally friendly method) and MnO2 nanosheets. In this composite probe, the fluorescence of the CDs (with excitation/emission peaks at 330/430 nm) is quenched by the MnO2 nanosheets through an inner filter effect. Introducing sulfide causes the MnO2 ...

Two new compounds, 4-(2-bromophenyl-4,5-diphenyl-imidazol-1-yl)aniline(probe 1) and 4-[2,4,5-tris(4-bromophenyl)-1H-imidazol-1-yl]aniline(probe 2), were synthesized via a soft and high-efficiency one-pot microwave- assisted method under solvent-free conditions. Their sensing to different metal ions was detected by UV spectrophotometry and fluoresce...

Silicon quantum dots have become one of the most popular nanomaterials in biological applications for their excellent biocompatibility and optical properties. Herein, we synthesized amino-functionalized silicon quantum dots ([email protected]) via a simple microemulsion method, in which silicon tetrachloride and allylamine were used as source of silicon an...

In this paper, a novel fluorescence carbon dots (FCDs) were proposed to use folic acid as the sole reactant via the pyrolytic way. The gotten FCDs were uniform in size distribution and had an excitation-independent emission feature, and their fluorescence quantum yield was 39.09%. Without additional modification, the acquired FCDs could be used to ...

Immune response stimulation and inactivation of chondroitinase ABC I in physiological condition have been limited its use in various clinical conditions as a bacterial enzyme drug. In the present study, we have investigated some structural and functional features of N∆89, C∆274 and N∆89C∆274; three designed truncated cABC I, in order to clarify the...

The authors describe a test stripe for fluorometric determination of the endocrine disruptor bisphenol A (BPA). Graphene quantum dots (GQDs) were immobilized on molecularly imprinted nanoparticles which then were placed on nitrocellulose paper. The GQDs display blue fluorescence (with excitation/emission peaks at 350/440 nm) which is reduced in the...

The extraordinary fluorescence quenching capability of graphene oxide (GO) was coupled to the specific recognition capability of aptamers to design a four-color fluorescent nanoprobe for multiplexed detection and imaging of tumor-associated proteins in living cells. Specifically, alpha-fetoprotein (AFP), vascular endothelial growth factor-165 (VEGF...
