Brown University engineers have demonstrated a technique for making 3D-printed biomaterials that can degrade on demand, which can be useful in making intricately patterned microfluidic devices or in making cell cultures than can change dynamically during experiments. “It’s a bit like Legos,” said Ian Wong, an assistant professor in Brown’s School of Engineering and co-author of the research. “We can attach polymers together to build 3D structures, and then gently detach them again under biocompatible conditions.”
They made their new degradable structures using a type of 3D printing called stereolithography...
