ABSTRACT We have developed a quickly responsive, and specific fluorescent assay for the detection of Au(III) on the basis of the formation of gold nanoparticles in the presence of HEPES, which cleave the C-I bond of I-BODIPY 1 to yield the highly fluorescent H-BODIPY 2.

    ABSTRACT: In this study, we present an ultrasensitive sensor based on nanoporous anodic alumina (NAA) for detection of gold (III) ions (Au3+ ions) using reflectometric interference spectroscopy (RIfS). Nanoporous anodic alumina, prepared by two-step electrochemical anodization, was functionalized with 3-mercaptopropyl-tirethoxysilane (MPTES) in order to selectively detect Au3+ ions. Thus prepared, MPTES-NAA sensors were exposed to different concentrations of Au3+ ions ranging from 0.1 to 750 µM and the changes in the effective optical thickness (∆EOT) were monitored in real-time. The linear range of these Au3+ sensors was from 0.1 to 80 µM, with a lower detection limit of 0.1 µM of Au3+ ions. Furthermore, the specificity of these MPTES-NAA sensors was validated by sequential exposure to 40 µM solutions of Fe3+, Mg2+, Co2+, Cu2+, Ni2+, Ag+, and Pb2+, resulting in negligible changes in EOT as compared to the same concentration of Au3+ ions. Detection of Au3+ ions in complex and environmentally and biologically relevant solvents such as tap-water and phosphate buffer solution (PBS) was also successfully carried out in order to demonstrate the real-life application of these sensors. Finally, the binding isotherm for Au3+ ions and thiol (SH) group of MPTES-NAA system was determined by fitting the changes in EOT to Freundlich and Langmuir isotherm models.

    ABSTRACT: To alleviate side reactions identified in an N-propargyl-rhodamine lactam sensing system, we devised the novel reaction-based sensing scheme for gold species based on the alkynophilicity. A fluorescein (2-ethynyl)benzoate underwent Au(III)-promoted ester hydrolysis selectively over other metal ions with high sensitivity, which accompanies a turn-on fluorescence change in pH 7.4 HEPES buffer. The work offers a versatile reactive moiety for the development of gold probes with improved sensing properties.

    ABSTRACT: Repeat proteins have recently emerged as promising candidates for the modular design of biohybrid platforms with a high degree of tunability. Consensus sequence tetratricopetide repeat (CTPR) proteins with increasing number of repeats were designed to probe the effects of protein shape on the morphology and resulting physicochemical properties of plasmonic gold nanoparticles. In a synthetic procedure analogous to the biomineralization processes in nature, CTPRs with 3, 6, or 18 tandem repeats were used as both the stabilizing and shape-directing agent. The electronic microscopy and spectroscopic studies indicate that both the [HAuCl4]/[CTPR] ratio and the CTPR shape have dramatic implications on the morphology and plasmon absorbance of the as-synthesized Au NPs. Induced plasmon ellipticity and fluorescence quenching data provide further evidence for the molecular interaction between CTPR and Au NPs or HAuCl4 species. Overall, this work elucidated the effects of CTPR protein shape on the morphology and plasmonic properties of Au NPs, which will further guide the rational design of modular protein based bioconjugate frameworks for colorimetric and enantiomeric biosensors.
