Zetasizer Nano proves indispensable for studying nanoparticles in water
Up and running since September 2009, Dr. Lau's laboratory is studying the behaviour and interactions of both natural and synthetic metal-based nanoparticles, such as metal oxides and metal sulphides, in water. This research has significant implications in areas such as water treatment and the biological uptake of manufactured nanoparticles.
By coupling the Zetasizer Nano with a Quartz Crystal Microbalance with Dissipation Monitoring (QCM-D) the Baylor team is able to correlate changes in particle size and charge with changes in adsorption of nanoparticles on environmental and physiological surfaces.
As well as holding the position of assistant professor at Baylor, Dr Lau is currently the particulate contaminant research committee chair of American Water Works Association (AWWA). Having used Zetasizer systems for the last ten years, when he set up the new laboratory he immediately understood the value of purchasing a Zetasizer Nano.
