Toward greener synthesis of gold nanomaterials: from biological to biomimetic synthesis
Get PDFIn the past two decades, the use of biomolecules, either from biological or biomimetic systems (or so-called biological or biomimetic synthesis), has emerged as a promising green approach to synthesize gold nanomaterials (Au NMs). Here, we describe recent progress on the biological and biomimetic syntheses of Au NMs. We focus our discussions on the selection principles of biomolecules, synthesis mechanisms involving biomolecules, recent evolution from biological to biomimetic synthesis, and the contributions of bioinspired synthesis to green production of Au NMs. We hope this review will provide a guideline for the green synthesis of Au NMs and other metal NMs, further paving their way toward practical applications in the field of biomedicine
Metal complexes of indole-3-acetic acid: synthesis, crystal structures, and Pb<sup>2+</sup> chemosensing by cation-exchange reaction
No full text<div><p>Two binuclear complexes [Cu<sub>2</sub>(IA)<sub>4</sub>(DMSO)<sub>2</sub>]·CH<sub>3</sub>OH (<b>1</b>), [Cd<sub>2</sub>(IA)<sub>2</sub>(phen)<sub>2</sub>I<sub>2</sub>] (<b>2</b>), and one 1-D {[Pb<sub>2</sub>(IA)<sub>4</sub>]·CH<sub>3</sub>OH}<sub>n</sub> (<b>3</b>) (IAH = indole-3-acetic acid, phen = 1,10-phenanthroline) have been prepared and characterized by single crystal X-ray diffraction. Both <b>1</b> and <b>2</b> are binuclear wherein the central Cu ions are bridged by IA in <b>1</b>, while Cd ions are bridged by I<sup>−</sup> in <b>2</b>. Complex <b>3</b> has a 1-D chain structure based on secondary building units (SBUs) of [Pb<sub>2</sub>(IA)<sub>4</sub>]. The three complexes show strong fluorescence emissions, and chemosensor behaviors for metal cations are investigated in mixed DMF/H<sub>2</sub>O (1 : 9 v/v) solvent. The results reveal that <b>2</b> shows effective sensing to Pb<sup>2+</sup>. The mechanism of the detection to Pb<sup>2+</sup> can be attributed to cation-exchange reaction between cadmium and lead ions.</p></div
