Picoyune: Miniaturized mercury sensor
December 2020

Researchers at Picoyune, an SRP-funded small business, are developing a miniaturized, low-cost mercury sensor and applying it to personal exposure monitoring. The portable device is a good fit for testing in the field as there is no need for heavy lab equipment or carrier gas. It is also a practical mercury monitor for vulnerable artisanal/small-scale gold mining communities and recently won the 2020 Artisanal Mining Grand Challenge.

Boston University: Integrative Epi-DNA and Gene Expression (iEDGE)
September 2020

Led by Stefano Monti, researchers at the Boston University SRP Center are developing computational tools that use short term toxicity tests to predict long term health outcomes. Their recent tool, iEdge, integrates data to predict changes to DNA that drive cancer.

UC Davis: Immunoassays to detect hazardous chemicals
June 2020

To address high costs for analyzing toxic substances in the environment as well as the need for more sensitive indicators of exposure to humans, University of California (UC), Davis SRP Center researchers pioneered the use of immunoassay technologies to detect hazardous chemicals. Immunoassays use antibodies to bind to a chemical of interest, and labels on the antibodies measure the presence and concentration of the chemical.

MIT: CometChip assay to detect DNA damage
March 2020

Massachusetts Institute of Technology (MIT) SRP Center researchers developed a new screening method that can detect a broad range of DNA damage in cells, including a common type of damage known as a bulky lesion. According to the researchers, this new method fills a gap in DNA damage testing and could make chemical safety testing faster, easier, and more accurate.

Microvi Biotechnologies: MicroNiche Engineering platform for organic compounds
December 2019

Microvi Biotechnologies, Inc., an SRP-funded small business, has recently shown unprecedented removal rates of 1,2,3-Trichloropropane (TCP) and co-contaminants using its co-metabolism treatment technology. TCP, which was historically used in solvents and soil fumigants, can leech into groundwater and subsequently household drinking water. It has been associated with increased risk for cancer along with various illnesses, including liver or kidney disease.

Northeastern University: Mobile report-back app
September 2019

The Northeastern University Puerto Rico Testsite for Exploring Contamination Threats (PROTECT) SRP Center and its partners at the Silent Spring Institute developed a mobile app to report individual research results back to study participants. The app was designed specifically for PROTECT and was adapted from the Silent Spring Institute's computer-based Digital Exposure Report-Back Interface (DERBI).
