3D printed biomaterials capable of dissolving upon demand

Scientists have created solutions that form dissolvable structures when 3D printed using stereolithography and have potential applications in scaffolds for artificial tissue and organs. Engineers from Brown University (RI, USA) have found a way to make 3D printed biomaterials that degrade on demand. This could be useful in making intricately patterned microfluidic devices or in making cell cultures than can change dynamically during experiments. Their study was published in the journal Lab on a Chip. "It's a bit like Legos," explained Ian Wong, co-author and assistant professor in Brown's School of Engineering. "We can attach polymers together to build 3D...
