Imaging bio-molecules and cells over extended periods of time is critical to understanding cellular processes and the causes of pathogenic diseases. Cadmium sulfide quantum dots are widely used for highly sensitive cellular imaging. The extraordinary photostability of these probes are highly attractive for the real-time tracking of bio-molecules and cells over time. PNNL scientists are exploring quantum dots with varying morphologies and trying to understand the variation of their spectroscopy associated with the morphological changes. The goal is to design probes that can be used to monitor cellular processes over extended periods. Dev Chatterjee provided the image. Others who contribute to the project include Matthew Edwards, Paul MacFarlan, Samuel Bryan and Jason Hoki. Image colored by graphic designer Jeff London.
