Nanoparticles

Nanoparticles are diverse and ever-growing in importance. Their characterization covers a wide range of challenges including:

Determination of size, concentration, content and conformation of nanomedicines including drug and gene delivery vehicles

Stability assessments of colloidal suspensions or nanoemulsions for controlled-release applications

Detection and identification of small quantities of industrial additives that may leach into the environment

Analysis of size distributions, zeta potential, and aggregation behavior dependent on solution conditions, including pH and ionic strength, of nanoparticles, emulsions and colloids utilized in food, cosmetics, semiconductor processing and a host of other consumer or industrial products

Wyatt’s Light Scattering Toolkit provides essential analytical instrumentation for nanoparticles combined with unparalleled levels of automation, sensitivity and resolution. By turning commonly utilized, low-throughput manual measurements into automated, high-throughput workflows, a plethora of new possibilities are opened to scientists and engineers working in this field.

The measurement techniques applied to nanoparticle and colloid characterization in Wyatt instruments are dynamic light scattering (DLS), multi-angle static light scattering (MALS), field-flow fractionation (FFF) and electrophoretic light scattering (ELS).
