Superresolution on the SPOT: Imaging Achieves Optical Sectioning
SYDNEY, Nov. 19, 2020 — A technique called SPOT (spectrum and polarization optical tomography) is providing researchers with a “street view” of lipid membranes surrounding cell organelles, thereby allowing insight into lipid dynamics. The work is the result of a collaboration between Peking University and the University of Technology Sydney-Southern University of Science and Technology (UTS-SUStech) Joint Research Centre for Biomedical Materials and Devices. The lipid membranes surrounding
Optogenetic Switch Now Works Both Ways: On and Off
STANFORD, Calif., April 24, 2014 — Since the beginning of optogenetics, the technique has been more effective at switching neurons on than off -- but not anymore. Building from Dr. Karl Deisseroth’s discovery about a decade ago of optogenetics — in which light-activated...
Brain Mapping Seeks New Paths
NEW YORK, March 10, 2014 — New imaging techniques could build new roadways in neural mapping and provide a better understanding of how the brain functions.
Controlling a deformable mirror with light
SOPHIA ANTIPOLIS, France – Adaptive optics are likely to get a boost through new technology using light instead of electricity to control a deformable mirror (DM) that comes with a continuous membrane rather than segmented pixels. The technology, developed at Institut...
Dual-Mirror Adaptive Optics Systems
Jun 7, 2010 — Researchers worldwide have leveraged advances in microelectromechanical systems (MEMS) mirror technology by using adaptive optics to correct for wavefront aberrations caused by distortion. Now, the next generation of adaptive optics systems is using...
Revealing Cell Membrane Mechanics
CHAMPAIGN, Ill., April 29, 2010 — Thanks to an interdisciplinary team of researchers, scientists now have a more complete understanding of one of the human body’s most vital structures, the red blood cell. Led by University of Illinois electrical and computer engineering...
Cells Respond to Laser Light
SAN FRANCISCO, Sept. 15, 2009 – For the first time, researchers have imported a light-controlled “on-off switch” from plants into a mammalian cell to instantly control a variety of cell functions by creating a hybrid protein that causes mouse cells to move in response to laser...
Cell Interactions Revealed
EUGENE, Ore., July 23, 2009 -- New findings that suggest putting lipids and other cell membrane components on manufactured surfaces to control like-charge attraction could lead to new classes of self-assembling materials for use in precision optics, nanotechnology, electronics...
Project Aims to Create New Materials, Nanodevices
BLACKSBURG, Va., April 25, 2007 -- A Multi-University Research Initiative (MURI) grant of as much as $7.5 million has been awarded to a four-university project that aims to use ionic liquids to develop electromechanical devices and high-performance membranes that could help power...
Microprocessing Technique Yields Ultrathin Membranes
STUTTGART, Germany, and MANCHESTER, England, March 5, 2007 -- Using a fabrication method for producing microprocessors, scientists have created what they said is the thinnest material that will ever exist: Carbon membranes that are only one atom thick. The membrane may allow them to examine individual...
Ultrathin Silicon Filter Sorts Single Molecules
ROCHESTER, N.Y., Feb. 15, 2007 -- A recently developed porous silicon membrane that is thousands of times thinner than similar filters used today sorts objects as small as proteins and has potential applications ranging from fuel cells to stem cells to microchip...
Nanoparticles Sneak Drugs into Cancer Cells
HOUSTON, Jan. 18, 2007 -- A new use for Buckyball nanoparticles has been discovered -- as "passkeys" that allow drugs to enter cancer cells. All living cells defend themselves by walling off the outside world. Cell walls, or membranes, form a protective cocoon around the...
Inner Lives of Cells Revealed
CAMBRIDGE, Mass., Oct. 18, 2006 -- For the first time, researchers can see every vibration of a cell membrane, using a technique that could one day allow scientists to create three-dimensional images of the inner workings of living cells. Studying cell membrane dynamics can help...
