New Use for Quantum Dots: Tracking the Pollination Process
STELLENBOSCH, South Africa, Feb. 18, 2019 — A pollination biologist from Stellenbosch University is breaking new ground in his field by using quantum dots to track and label individual pollen grains. His novel, low-cost method could enable biologists to track the whole pollination process, from the first visit by a pollinator to the endpoint — either the pollen grain’s successful transfer to another flower’s stigma or its loss along the way.
Color-Coded Markers Diagnose Disease Through Eyes
SAN DIEGO, Aug. 17, 2012 — New fluorescent probes that change color when they encounter brain disease markers found in the eye could offer a simpler way to identify neurodegenerative disease and distinguish between closely related disorders such as Parkinson’s, Alzheimer’s...
Glass-Based LEDs Go UV
LOS ALAMOS, N.M., Feb. 28, 2012 — Inorganic LEDs that emit in the difficult-to-achieve ultraviolet range were produced by embedding nanocrystals in glass, a step toward using such devices in biomedical applications.
Smart Lasers Could Make Biopsies Painless
EAST LANSING, Mich., Feb., 2, 2011 — Biopsies in the future may be painless and noninvasive, thanks to smart laser technology being developed at Michigan State University. To test for skin cancer, patients today must endure doctors cutting away a sliver of skin, sending the...
Encapsulation Key to In Vivo Imaging
Jan 1, 2003 — Recent research indicates that quantum dots could someday replace fluorescent markers, such as organic dyes and fluorescent proteins, in some biological imaging applications. To compete, though, these nanometer-scale semiconductor crystallites must...
