Molecular Nucleic Acid Detection Technology to Empower Patients with Self-Testing Capabilities
This technology provides an innovative molecular diagnostic assay for high-speed, sensitive, and specific detection of nucleic acids from SARS-CoV-2 or other pathogens, performed in a newly devised reusable base unit with pathogen-specific, one-time-use consumables – first prototyped at the Wyss Institute, then transformed into an inexpensive, reliable and manufacturable detection system by 3EO Health. -
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. -
Toehold Switches for Synthetic Biology
The burgeoning field of synthetic biology is designing artificial gene circuits that recognize molecules in their environment and respond by regulating genes with desired activities. In the future, such capabilities could allow the engineering of cells as diagnostic or therapeutic devices, factories for the production of clinically or industrially coveted molecules, and as specialized devices... -
Toehold Probes for Nucleic Acid Detection
The accurate detection of specific DNA or RNA sequences is important for many research and diagnostic applications, and unspecific detection of similar sequences that can differ by only a single nucleotide can give false positive results. In addition, researchers and clinicians would like to accurately test for presence or absence of multiple single base changes... -
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...

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/AnimationBeating Back the CoronavirusWhen the coronavirus pandemic forced Harvard University to ramp down almost all on-site operations, members of the Wyss Institute community refocused their teams, and formed new ones, in order to fight COVID-19 on its multiple fronts. These efforts include building new pieces of personal protective equipment that were delivered to frontline healthcare workers, developing new... -
Video/AnimationLighting up proteins with Immuno-SABERThis animation explains how Immuno-SABER uses the Primer Exchange Reaction (PER) to enable the simultaneous visualization of multiple proteins in tissues in different applications. Credit: Wyss Institute at Harvard University. -
Video/AnimationSABER-FISH: Enabling the sensitive and multiplexed detection of nucleic acids within thick tissuesThis animation shows how SABER-FISH uses a suite of DNA nanotechnological methods that together enable the sensitive and multiplexed detection of DNA and RNA targets within cells and thick tissues. Credit: Wyss Institute at Harvard University -
Video/AnimationToehold Exchange ProbesThis animation explains how toehold probes consisting of a “probe strand” and a “protector strand” are assembled and how they leverage thermodynamic principles to allow the specific detection of a correct target sequence, or to prevent them from detecting a spurious target sequence that can differ from the correct target sequence by only a single...
