Dynamic Light Scattering: A Powerful Tool for In Situ Nanoparticle Sizing

Due to surface effects and quantum size effects, nanomaterials have properties that are vastly different from those of bulk materials due effects. The particle distribution plays an important role in chemical physical properties. measurement control this parameter crucial for nanomaterial synthesis. Dynamic light scattering (DLS) is a fast non-invasive tool used measure size, stability solutions or suspensions during preparation. In review, we focus on the situ sizing preparation form colloids, especially metal oxide nanoparticles (MONs). measuring principle, including overview techniques, advantages limitations theories DLS were first discussed. instrument design was then investigated. Ex-situ configuration DLS, sample preparations, conditions reaction cell studied. MONs monitored by presented, taking into consideration both ex configuration.
