Standardizing Solutions to Enabling Platforming of Process Analytical Technology (PAT) Deployments
April 24th 2023Gary McGeorge, Scientific Director at Bristol-Myers Squibb, spoke to us of the benefits and challenges associated with establishment of consistent resolutions while facilitating the steps associated with the implementation of process analytical technology (PAT).
Pump–Probe Microscopy: Theory, Instrumentation, and Applications
April 1st 2017Excited state dynamics provides an intrinsic molecular contrast of samples examined. These dynamics can be monitored by pump probe spectroscopy which measures the change in transmission of a probe beam induced by a pump beam. With superior detection sensitivity, chemical specificity and spatial-temporal resolution, pump probe microscopy is an emerging tool for functional imaging of non-fluorescent chromophores and nanomaterials. This article reviews the basic principle, instrumentation strategy, data analysis methods, and applications of pump probe microscopy. A brief outlook is provided.
