Mimicking Biological Systems
|
|
FOR THE PAST CENTURY, the petri dish has been the best thing available to study cells and tissues outside the body. But cells in a petri dish inhabit an environment that looks nothing like their natural milieu. Engineers and physical scientists, in collaboration with biologists, are demonstrating that the channels and wells of microfluidic devices can mimic the chemistry and physics of biological systems in ways that reveal hitherto unknown biology.
