Small-Molecule Microarrays

This is a part of Scanning Life's Matrix: Genes, Proteins, and Small Molecules


Microarray technology is useful for screening many small molecules at once. Automated devices have made it possible for thousands of different small molecules to be printed as an array of spots on a glass slide. A single type of protein which has been tagged with a fluorescent marker can then be washed across the array. Any small molecule that binds to the protein can be detected by scanning for spots that are fluorescent.
