DNA Nanostructures for Drug Delivery
Researchers at the Wyss Institute have developed two methods for building arbitrarily shaped nanostructures using DNA, with a focus on translating the technology towards nanofabrication and drug delivery applications. One proprietary nanofabrication technique, called “DNA-brick self-assembly,” uses short, synthetic strands of DNA that work like interlocking Lego® bricks. It capitalizes on the ability to program...
Putting Biofilms to Work
A team at the Wyss Institute sees biofilms as a robust new platform for designer nanomaterials that could treat inflammatory bowel diseases, clean up polluted rivers, manufacture pharmaceutical products, fabricate new textiles, and more. A novel protein engineering system called BIND, which stands for Biofilm-Integrated Nanofiber Display, could be the essential ingredient in tomorrow’s probiotic...
Programmable Robot Swarms
Collective behaviors enable animals like ants to build huge complex structures through the distributed actions of millions of independent agents. These collective behaviors are inspiring engineers at the Wyss Institute to build simple mobile robots that harness the demonstrated power of the swarm, performing collective tasks like transporting large objects or autonomously building human-scale structures....
Recent decades have seen rapid development in the manufacture of microelectromechanical systems (MEMS) at the micrometer scale, mostly based on silicon wafer processing techniques, with characteristic length scales of millimeters to nanometers. However, standard MEMS techniques are often inappropriate for producing machines with complex 3D topologies and varied constituent materials at the mesoscale, at sizes...
4D Printing of Shapeshifting Devices
Organisms, such as flowers and plants, have tissue compositions and microstructures creating dynamic morphologies that can shapeshift in response to changes in their environments. Researchers at the Wyss Institute have mimicked a variety of such dynamic shape changes like those performed by tendrils, leaves, and flowers in response to changes in humidity or temperature with...
