3-D Stress Map Reveals Embryonic Heart Defects
CLEVELAND, Nov. 1, 2012 — Stresses induced in an embryonic heart by blood flow have been visualized for the first time in 3-D using an optical coherence tomography (OCT) method. The technique could provide new insight into how and why heart defects develop.
Microscope Uses Broadband Light to Track Cell Flow
HAIFA, Israel, May 24, 2012 — A novel optical instrument no bigger than a breadbox can take real-time images of blood coursing through our veins without harsh and short-lived fluorescent dyes.
Laser-Based Method Detects Optical Forces in Blood
WASHINGTON, Oct. 19, 2011 — A new laser-based analysis method can detect optical pressure differences among classes of blood cells, and it doesn't rely on prior knowledge, antibodies or fluorescent labels for discrimination. Scientists at the US Naval Research Laboratory...
Molecular Sensor Changes Color When Stressed
PHILADELPHIA, Aug. 23, 2011 — It is helpful — even life-saving — to have a warning sign before a structural system fails, but when the system is only a few nanometers in size, having a sign that is easy to read is a challenge. Now, however, a newly developed...
Five Bucks and a Cell Phone Builds a Flow Cytometer
LOS ANGELES, July 27, 2011 — At the University of California, researchers from the Henry Samueli School of Engineering and Applied Science have developed a compact, lightweight and cost-effective optofluidic platform that integrates imaging cytometry and fluorescent microscopy...
Beaming through to NOVEL USES for HOLOGRAPHY
Feb 28, 2010 — Typically, green, simple three-dimensional images of objects on flat paper are not unknown to today’s kids – or to anyone who has grown up during the past few decades. We encountered them first as wonderments – optical tricks that astounded and...
Light Positions Particles
WEST LAFAYETTE, Ind., Dec. 3, 2008 -- Light created by lasers and holograms has been used to precisely position many tiny particles within seconds. The technique has the potential to become a new tool for analyzing biological samples or creating devices using nanoassembly. The...
