Lasers Move Diamond Nanoparticles into Bio Applications
SAPPORO, Japan, March 31, 2021 — Scientists from Hokkaido University, Osaka Prefecture University, and Osaka University showed the ability to use laser beams of different wavelengths, and from opposing directions, to move diamond nanoparticles that are roughly 50 nm in size in a proof-of-concept experiment. The demonstrated approach builds on the fundamental principles and outcomes of optical trapping and aims to establish a foundation future and forthcoming applications in biological imaging and quantum
What Ever Happened to Medical Surveillance?
Mar 30, 2021 — Did you know there was a time when eye exams were suggested every three years for users of Class 3B or Class 4 lasers? The rules around so-called medical surveillance began to change in 2007, when the American National Standards Institute’s...

Managing Temperature-Based Performance Drift for Coatings
Mar 29, 2021 — What happens when optical coatings get very cold? There should be little difference in a thin film’s optical performance at room temperature test conditions versus its use conditions. But this is not always the case. Performance varies at different...
Atomic Lattice Excitation Yields Understanding of Quantum Dots’ Limits
MENLO PARK, Calif., March 29, 2021 — At low energy levels, quantum dots are able to absorb light and convert it to a different color at nearly 100% efficiency. At higher excitation energies required for brighter screens and other technologies, the level of efficiency drops...
Light Delivers Hydrogen from Nonphotosynthetic Microorganisms
LISBON, Portugal, March 29, 2021 — A team in Portugal has introduced a method for the sustainable conversion of solar energy into hydrogen, relying on biohybrid systems — combinations of nonphotosynthetic materials, bacteria, and semiconductor nanoparticles. The ability of...
DNA Origami Supports Applications In and Beyond Life Sciences
REGENSBURG, Germany, March 26, 2021 — A European research team developed a dye- and DNA programming-based approach for counting molecules present within individual complexes. The approach supports biomedical and life sciences applications, as well as those involving OLEDs, solar cells,...
Fabrication Method Could Expand Perovskite Production
LOS ALAMOS, N.M., March 26, 2021 — A simple, synthetic process for fabricating stable perovskite solar cells has overcome a preventative challenge to large-scale production, and, as a result, to product commercialization. A team from Los Alamos National Laboratory and National Taiwan...
Kinetic River Develops Autofluorescence Removal Technology
