Documentary Screening: The Edge of Joy

This film chronicles the lives of Nigerian doctors, midwives and families at the frontline of maternal care and explores the complexities of bringing emerging health technologies to the developing world. The screening will be followed by a discussion with an expert panel, chaired by Dr Sheelagh McGuinness

Dynamic Light Scattering (DLS) for Particle Size Distribution (PSD) and Zeta Potential

Malvern Instruments ZetaSizer HPPS is a non-invasive technique and provides information about size and PSD of particles and molecules dispersed and dissolved in a liquid. The instrument has a laser light source which is used to illuminate the particles. Then, the generated scattered light fluctuates at a speed depending on the particle size. With the velocity of the Brownian motion, derived from the analysis of these fluctuations, and the Stokes-Einstein equation, particle size can be obtained. Particles lower than 1nm in size can be analysed by using this instrument and the minimum sample volume requirement is 20μL
