DNA Nanotechnology Tools: From Design to Applications
DNA nanostructures with their potential for cell and tissue permeability, biocompatibility, and high programmability at the nanoscale level are promising candidates as new types of drug delivery vehicles, highly specific diagnostic devices, and tools to decipher how biomolecules dynamically change their shapes, and interact with each other and with candidate drugs. Wyss Institute researchers are...
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...
Multiplexed Molecular Force Spectroscopy
Programmable DNA nanoswitches, invented at the Wyss Institute, can now be used in combination with a benchtop Centrifuge Force Microscope (CFM) as a highly reliable tool to observe thousands of individual molecules and their responses to mechanical forces in parallel. By analyzing the responses of single molecules under conditions where they experience such forces, it is possible...
Inexpensive Super-Resolution Microscopy
Wyss Institute scientists have developed a highly versatile and inexpensive microscopic imaging platform designed to visualize objects with molecular-scale resolution and unprecedented complexity. The DNA-powered imaging technology can reveal the inner workings of cells at the single molecule level, using conventional microscopes found in most laboratories. Key to the Wyss Institute’s DNA-driven imaging super resolution...

Video/AnimationWhat Is BIOMOD?BIOMOD is a biomolecular design competition for students created by the Wyss Institute for Biologically Inspired Engineering at Harvard University. Each year BIOMOD holds a Jamboree, an annual conference at which all BIOMOD teams convene to present their work from the summer. This year’s Jamboree will take place in Genentech Hall at UCSF in San Francisco,...
Video/AnimationAuto-cyclic Proximity RecordingThis video explains how “Auto-cycling Proximity Recording” works to identify pairs of nearby molecular targets and how it can be used as a tool to decipher the geometry of 3-dimensional engineered and natural molecules.

Audio/PodcastWilliam Shih: Lego-Style Construction of Future Therapeutics From DNAListen to Wyss Core Faculty member William Shih’s lecture on how custom molecular shapes can be designed using DNA building blocks and how these minuscule devices could have a profound impact on fields ranging from molecular biophysics to therapeutics to nano-optics for decades to come. Shih’s lecture is part of the ArtScience lecture series at...
Audio/PodcastDisruptive: Molecular RoboticsHow can DNA be programmed to build novel structures, devices, and robots? We have taken our understanding of DNA to another level, beginning to take advantage of some of DNA’s properties that have served nature so well, but in ways nature itself may have never pursued. Humans can now use DNA as a medium for...
