Chemistry of Imaging Agents
The use of chemistry in the design and use of imaging agents has given us the ability to change the appearance of what we image in very specific and meaningful way. We do this to improve the information content in the images we wish to capture. In Biomedical Imaging, novel nanoparticle contrast agents are designed to target to specific tumors and even single tumor cells, and improve our ability to detect early changes. The use of different pigments and dyes give paintings the color and contrast we appreciate. Small fluorescent chemical probes can be used to identify sub-cellular structures and molecules, and track these over time. Imaging agents, and the chemistry to make and modify these, have a broad and valuable influence across many different areas of imaging.
