Keeping track of particles-in-a-chip

摘要

How does trapping a nanoparticle in a microdevice affect its reactions?US scientists are answering this question thanks to a straightforward method using fluorescent tags.Meghan Caulum and Charles Henry at Colorado State University in Fort Collins have developed what they say is'a simple,inexpensive way to monitor reactions at the surface of magnetic particles within a microfluidic device.'
