Synthesis of gold nanoparticles stabilised by metal-chelator and the controlled formation of close-packed aggregates by them

摘要: Nanoparticles have properties that can be fine -tuned by their size as well shape. Hence, there is significant current interest in preparing nano -materials of small dispersity and to arrange them close -packed aggregates. This manuscript describes ways synthesising gold nanoparticles using a metal -chelator derivative 1, stabiliser. Controlled synthesis conditions lead formation thereby indicating the ability 1 act efficient The formed were characterised transmission electron microscopy UV-Vis spectro- scopy. TEM analysis showed dense aggregates nanoparticles. ascribed inter-particle hydrogen bonding possible carboxylic acid moiety leads aggregation. aggregation controlled pH solution employed for dispersing particles.
