• DoriVac: DNA Origami-Based Vaccines for Combination Immunotherapy
  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 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...
• 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.
• 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.
• abbieSense: Anaphylaxis Diagnostic
  The molecule histamine plays a primary role in the anaphylaxis reaction, which is a major cause of illness and death in people with severe allergies. Histamine is a very small molecule composed of only seventeen atoms, making it a challenging target to detect. To date, no diagnostic test exists that can measure histamine levels accurately...

• Brigham-Wyss DxA
  The Wyss DxA's clinical partners from Brigham and Women’s Hospital identify the most pressing unmet diagnostic needs, provide access to high-quality patient samples for our Biomarker Discovery Laboratory (BDL) and Brigham-Wyss DxA collaborators, and provide invaluable feedback and guidance on the engineering and validation of cost-effective, sensitive, and specific diagnostic tests.
• Kraft Heinz Partnership
  The Kraft Heinz company approached the Wyss Institute for help to achieve its ambitious goal to make its food products healthier, resulting in a novel technology that is ripe for commercialization.

  Illuminating Biological Context with Josie Kishi – Translation by Fifty Years
  Technologies like next-generation sequencing allow us to understand which RNA transcripts and proteins are expressed in biological tissues. However, it’s often equally important to understand how cells or molecules are positioned relative to one another! Whether it be a cell changing its shape, an organelle ramping up a metabolic process, or a DNA molecule traveling...
