Abstract: We present a new method for performing passive probe microrheology. Using a simple theoretical framework, we show how probes’ mean-squared displacements can be extracted by analyzing intensity fluctuations in optical microscopy videos via differential dynamic… read more here.

Abstract: Few techniques can reliably measure the dynamics of colloidal suspensions or other soft materials over a wide range of turbidities. Here we systematically investigate the capability of Differential Dynamic Microscopy (DDM) to characterise particle dynamics… read more here.

Abstract: Differential dynamic microscopy (DDM) typically relies on movies containing hundreds or thousands of frames to accurately quantify motion in soft matter systems. Using movies much shorter in duration produces noisier and less accurate results. This… read more here.
