Fluorescent Dye-Based Device Could Help Prevent Tooth Decay
SEATTLE, March 24, 2022 — An optical device in development at the University of Washington (UW) could help prevent tooth decay by identifying at-risk teeth before cavities have had a chance to start to develop. The prototype, called O-pH, uses a low-power light system and an...
Optochemical Storage System Cuts Costs, Resists Data Corruption
CAMBRIDGE, Mass., Oct. 25, 2021 — Fluorescent dyes could play a central role in the quest for optical methods to ensure reliable and cost-effective data storage. A Harvard University research team has devised a way to store digital data in fluorescent dye molecules, using...
Polymer Molecules Fluoresce After Chemical Adjustments
ZURICH, April 8, 2021 — ETH Zurich researchers have introduced a method that relies on chemical adjustments occurring in fluorescent organic polymer molecules to generate a broad palette of color. The approach is an alternative to mixing different molecules to achieve...
SMILES Brighten Fluorescent Materials
BLOOMINGTON, Ind., Aug. 11, 2020 — A joint effort between researchers at Indiana University and the University of Copenhagen has yielded a new class of materials, called small-molecule ionic isolation lattices (SMILES), which the researchers say are the brightest fluorescent...
Dye Boosts Bioimaging Capability
NOTRE DAME, Ind., June 15, 2020 — Fluorescence imaging has been a boon to research and medicine because of its ability to examine affected areas noninvasively. But the dyes used for these purposes have their disadvantages, and as resolution needs have grown stronger, the stakes for...
Imaging Agent Illuminates Cancer and Surrounding ‘Hijacked’ Cells
ST. LOUIS, March 18, 2020 — Scientists at Washington University School of Medicine have developed an imaging agent that can identify multiple types of tumors as well as the surrounding normal cells that the cancer uses as a shield against attempts to destroy it. “This...
Quantum Dots Deliver Vaccines, Encode Vaccination History in the Skin
CAMBRIDGE, Mass., Jan. 7, 2020 — Using fluorescent quantum dots, an MIT research team has created a way to administer vaccinations and record a patient’s vaccination history in the skin. The researchers developed a microneedle platform that can selectively deliver...
Fluorescent Dye Helps Detect Reactive Oxygen Species
BATH, England, Dec. 27, 2019 — Scientists at the University of Bath have developed a fluorescent tool for detecting reactive oxygen species based on a chemical found in mushrooms. Reactive oxygen species (ROS), such as free radicals and peroxides, are produced in cells under...
Multispectral Camera Detects Tumors During Surgery
MANNHEIM, Germany, Nov. 11, 2013 — A multispectral camera that simultaneously displays several fluorescent dyes and the reflectance image in real time could help surgeons ensure that they don’t leave behind tiny pieces of malignant tumors. Obviously, cancer patients have a...
Nanobubbles Destroy Some Cells, Treat Others
HOUSTON, Dec. 4, 2012 — A single laser blast can activate plasmonic nanobubbles that selectively kill diseased cells while at the same time treating others, and leaving neighboring healthy cells untouched.
Microbubble Imaging Wins Nanoengineering Prize
SAN DIEGO, May 11, 2012 — A new “blinking microbubble” technique that images deeper inside the body for improved breast cancer diagnostics has won the grand prize at the University of California, San Diego’s Jacob School of Engineering Research Expo 2012.
Cancer Genes Detected with Liquid Lasers
ANN ARBOR, Mich., Feb. 1, 2012 — Genes linked to cancer and other diseases may now be easier to detect with a new method that uses liquid lasers to distinguish mutated DNA from healthy DNA by a single base. “We found a clever way to amplify the intrinsic difference in the signals,”...
Shining a Black Light on Coating Inspections
Nov 1, 2010 — The highest-quality, longest-lasting coatings available to consumers are installed at the factory. Factory finishes are applied in a controlled environment using quality materials and highly specialized equipment. The protective...
What's New with PCR
Sep 1, 2009 — Polymerase chain reaction (PCR), the workhorse of biological analysis, is used in areas ranging from criminal investigations and disease diagnosis to biological research. For example, it is the test that determines whether a strand of hair found at...
