Colloidal stability and coagulation kinetics study of different sized sulphur nanoparticles

Year: 2012

Type: article

Abstract: Colloidal stability and coagulation kinetics of orthorhombic and monoclinic sulphur nanoparticles (SNPs) were determined in terms of their size distribution along a gradient of temperature, dilution and time-drive. Dynamic light scattering (DLS) was used to determine the size and shape of SNPs in the colloidal suspension. A simultaneous study with high-resolution scanning and transmission electron microscopy was undertaken to evaluate the shape and actual (core) size of SNPs. All the DLS-derived data were statistically analysed to determine the effect of temperature, dilution and time drive on the growth kinetics of SNPs in the colloidal medium. Polymer-stabilised orthorhombic (∼10 nm) and monoclinic (∼15 nm) SNPs were found to be highly stable in the variable range of physical conditions and validates their active use in antimicrobial drug formulations.
