DNA Nanoswitches: “Lab-on-a-Molecule” Drug Discovery
The Lab-on-a-Molecule platform leverages the Wyss Institute’s DNA nanotechnology technology for the high-throughput, low-cost screening of a wide range of chemical and biologic compounds to enable the discovery of first-in-class therapeutics for various conditions.
DoriVac: Boosting Antigen-specific Immune Responses with DNA Origami-Based Vaccines
Personalized cancer and infectious disease vaccine platform harnessing DNA nanotechnology to control the co-delivery and co-presentation of tumor antigen and adjuvant ligands to immune cells with nanoscale precision. This approach has potential to trigger enhanced immune responses against tumors and infectious pathogens.
Crisscross Nanoseed Detection: Nanotechnology-Powered Infectious Disease Diagnostics
This nanotech-based diagnostic platform uses a unique nucleation mechanism that assembles a DNA "nanoseed" in the presence of a pathogen-derived biomarker that then is amplified within 15 minutes to create a signal for easy detection. It is highly robust, and cost-effective, and can be adapted to detect a variety of biomarkers.
DNA Nanotechnology Tools: From Design to Applications
A suite of diverse, multifunctional DNA nanotechnological tools with unique capabilities and potential for a broad range of clinical and biomedical research areas. Our DNA nanotechnology devices were engineered to overcome specific bottlenecks in the development of new therapies and diagnostics, and to help further our understanding of molecular structures.
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...
Video/AnimationSeed-dependent crisscross DNA-origami slatsThis animation explains how the newly invented crisscross origami method can be used to build functionalized micron-scale DNA megastructures composed of many unique DNA origami “slats,” each with their own complexity and interactive properties.

Video/AnimationDNA Nanoswitch CalipersThe world’s tiniest ruler for biomolecules has been created by researchers at the Wyss Institute at Harvard University, Harvard Medical School, and Boston Children’s Hospital. DNA Nanoswitch Calipers can measure very small peptides to better understand their structure and function, and enable them to be quickly identified in mixed samples. These insights could lead to...

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,...
