The CD BioSciences biophysical characterisation laboratories are equipped with state-of-the-art instruments for studying proteins, nucleic acids, lipids, and complexes. Researchers can benefit from our Malvern Zetasizer ZSP-Dynamic Light Scattering (DLS) System-based biophysical characterisation services.
The Zetasizer Nano ZSP incorporates three techniques in a single compact unit, and has a range of options and accessories to optimize and simplify the measurement of different sample types.
Dynamic Light Scattering is used to measure particle and molecule size. DLS measures the diffusion of particles moving under Brownian motion, and converts this to size and a size distribution using the Stokes-Einstein relationship.
Measurement of size as a function of concentration enables the calculation of kD, the DLS interaction parameter.
The Microrheology option uses the DLS measurement of tracer particles to probe the structure of dilute polymer and protein solutions.
Laser Doppler Micro-electrophoresis is used to measure zeta potential. An electric field is applied to a solution of molecules or a dispersion of particles, which then move with a velocity related to their zeta potential. This velocity is measured using a patented laser interferometric technique called M3-PALS (Phase analysis
The Zetasizer Nano ZSP incorporates three techniques (dynamic and static light scattering, microelectrophoresis) in a single compact instrument. There is a range of options and accessories so researchers can measure: particle and molecule size distributions, zeta potential, and molecular weights.
