Self-folding plastics target microfluidic devices
from Plastics Today
Plastic films that mimic the self-folding movements of plants may hold the key to developing a new generation of microfluidic devices. The new films fold when they respond to stimuli and they can also organize into complex three-dimensional structures. "The self-folding films can be used to encapsulate cells because cells remain encapsulated in the self-folded capsule but the chemicals can freely diffuse to the cells since the wall are not tightly closed," Dr. Leonid Ionov, a German researcher, said. "Or they can be used to build channels for microfluidic devices."
