BI-200SM Goniometer Used in Nanoparticle Dynamic Light Scattering

In the study entitled “Strain specificity in Antimicrobial Activity of Silver and Copper Nanoparticles,” four strains of Escherichia coli, three strains of each Bacillus subtilis and Staphylococcus Aureus were used to assess the antimicrobial properties of silver and copper nanoparticles. The Brookhaven BI-200SM Goniometer was used in particle size measurement of suspended nanoparticles via dynamic light scattering (DLS). Bacterial experiments […]

Guide for Dynamic Light Scattering (DLS) sample preparation

Nomenclature The term solvent refers the pure solvent used to prepare the diluent. Examples of solvents are toluene or water. The diluent may also be referred to as the liquid in DLS textbooks. Diluents are solvent with additives, for example a 10% by weight methanol in water or a 10 mM KNO3 salt in DI […]

The Measurement of Very Small Particles by Cross Correlation or Avalanche Photodiode Detectors

Walther W. Tcharnuter and Bruce. B. Weiner, Brookhaven Instruments Corporation, New York, USA (Note: this article by the founders of Brookhaven Instruments was originally published in the 1990s) The measurement of particle size using dynamic light scattering, also known as photon correlation spectroscopy, is well known. Scattered laser light is autocorrelated, fit either with cumulants […]
