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.
FcMBL: Broad-Spectrum Pathogen Capture for Infectious Diseases
Microbial infection is the cause of life-threatening cases of sepsis, meningitis and multiple other diseases that are major causes of death world-wide. Equally prevalent are pathogenic contaminants in our environment, food, and manufacturing processes. In each case, the presence of dangerous microbes must be confirmed, and when they are found, they need to be removed,...
AquaPulse: Portable Off-the-Grid Water Purification
Globally, more than 2 billion people are forced to use a drinking water source that is contaminated with bacteria, parasites, and other pathogens, and an estimated 502,000 people die each year from diarrhea as a result of unsafe water. While a majority of the world has access to improved water sources, many are often contaminated;...
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...
Since the 1940s, researchers have thought of using gene drives to eradicate populations of pests and disease vectors, and to reduce or eliminate invasive species that wreak havoc on natural ecosystems. The idea of a gene drive stems from nature itself, where in sexually reproducing organisms a certain version of a gene is preferentially passed...
Video/AnimationeToehold: an RNA-detecting control element for use in RNA therapeutics, diagnostics and cell therapiesThis animation shows an example of an eToehold that detects and signals the presence of a specific viral RNA in a human cell. After the virus has injected its RNA into a host cell, the RNA acts as a “trigger RNA” by binding to a complementary sequence within the eToehold specifically engineered for its detection....
Video/AnimationRapid Triage Test for Active Pulmonary TuberculosisThere’s a large unmet need for accurate, fast, and inexpensive diagnostics for active tuberculosis (ATB), which claims the lives over a million people per year. A team of researchers from the Wyss Institute for Biologically Inspired Engineering, The Broad Institute of Harvard and MIT, Brigham and Women’s Hospital (BWH), and several other collaborating institutions have...
