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 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...
Toehold switches as versatile tools for synthetic biology applications
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...
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...
Pathogen Capture Technology for Infectious Disease Therapeutics and Diagnostics
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,...
