Rotating Laser Enables Faster, Longer Imaging of Cells
FREIBURG, Germany, April 20, 2022 — A microscopy method developed at the University of Freiburg is able to resolve cellular-level detail without fluorescence, enabling observations 100 to 1000× longer and 10 to 100× times faster, with almost double the resolution. The technique is called rotating coherent scattering (ROCS). It uses a rapidly rotating blue laser beam, causing lightwaves to scatter at the structures of cells to generate images. “We are exploiting several physical phenomena familiar from
Imec and MiDiagnostics to Commercialize COVID-19 Breath Sampler
LEUVEN, Belgium, Oct. 25, 2021 — Imec, a research and innovation hub in nanoelectronics and digital technology, has signed a nonexclusive licensing agreement with miDiagnostics, a spinoff of imec in collaboration with Johns Hopkins University, to commercialize technology that...
Modified Antibodies Boost Photodynamic Therapy’s Efficacy
COLLEGE STATION, Texas, May 25, 2021 — Adding antibodies to photodynamic therapies can bolster their efficacy, according to research conducted by Texas A&M University and the University of São Paulo. The work reviewed the existing approaches to photodynamic therapies and...
Optical Diagnostic Platform Detects Multiple Viruses in Blood
ROCHESTER, N.Y., Jan. 8, 2021 — University of Rochester researchers are developing an optical chip on a disposable card that is capable of detecting exposure to multiple viruses, within a minute and from a single drop of blood. The $1.7 million project is led by Benjamin Miller, a...
Specialized Optical Mirrors Set to Unlock the Universe’s Darkest Mysteries
May 4, 2016 — Large telescopes all across the world stare into the sky day and night, waiting to uncover the secrets of the cosmos. For the Hobby-Eberly Telescope, the world’s third-largest optical telescope, located at The University of Texas at...
Nano-FTIR Offers Versatility in Protein Studies
SAN SEBASTIÁN, Spain, & Berlin and Martinsried, Germany, Dec. 17, 2013 — A new technique called Fourier transform infrared nanospectroscopy (nano-FTIR) overcomes the diffraction limits of mid-infrared spectroscopy for label-free chemical and structural imaging of protein structures with high resolution (less than 30 nm)...
Spinning-disk Microscope Peers into the Heart of a Cell
LONDON, Oct. 10, 2013 — A new microscopy technique with unprecedented focusing ability will allow structures deep within cells, including viruses and bacteria, to be investigated for the first time.
Metamaterials Pave Way for Superlens
ITHACA, N.Y., Nov. 11, 2011 — Casting tiny, oddly shaped metal structures inside plastic molds could give a boost to creating metamaterials for making “superlenses” that can image proteins, viruses and DNA. Metamaterials, which offer new ways to manipulate...
DARPA Awards Georgia Tech $4.3M
ATLANTA, Dec. 8, 2010 — A new class of sensors able to detect multiple biological and chemical threats simultaneously with unprecedented performance may soon be within reach, thanks to the establishment of a multimillion-dollar research center led by Georgia Institute of...
NanoImaging Receives $200K SBIR Grant
SAN DIEGO, April 23, 2010 — NanoImaging Services Inc. has received a Small Business Innovation Research (SBIR) grant from the National Institutes of Health through the National Center for Research Resources to develop a new method for quantitative characterization of...
Light Squeezed Even Tighter
ADELAIDE, Australia, Nov. 13, 2009 – Scientists at the University of Adelaide proved that light can be squeezed into much tighter spaces than previously thought, thanks to new breakthroughs in the theoretical understanding of how light behaves at the nanoscale.
Optical Trap Holds Viruses
BARCELONA, Spain, Oct. 22, 2009 – A Spain-Canada research collaboration developed a new method to gently trap, manipulate and study tiny, active objects as minuscule as viruses without inflicting any damage. The team demonstrated that it is possible to use the force of light to hold...
PECASE Funds Photonics Work
WASHINGTON, July 13, 2009 -- Scientists and engineers focused on photonics-related work were among the 100 named by President Barack Obama as recipients of the Presidential Early Career Awards for Scientists and Engineers (PECASE), the highest honor bestowed by the US...
Viralytics strengthens portfolio
Jun 1, 2009 — In Sydney, Australia, Viralytics Ltd. has received a US patent for the use of Echoviruses, including the proprietary Evatak formulation of Echovirus Type 1, to treat all cancers expressing the integrin a2b1 molecule. Included are ovarian, prostate...
3-D MRI Extends to Nanoscale
SAN JOSE, Calif., Jan. 13, 2009 – The creation of a microscopy tool with ultrahigh resolution, combined with an advanced 3-D image reconstruction technique, has enabled scientists to demonstate magnetic resonance imaging (MRI) on biological objects such as viruses. The achievement...
Virus Imaged in Great Detail
WEST LAFAYETTE, Ind., March 6, 2008 -- Single-particle electron cryomicroscopy, also known as cryo-EM, has been used to capture a 3-D image of a virus with near atomic-level resolution, the highest level of detail achieved for a living organism of that size. A team led by Wen Jiang,...
Bird Flu Biosensor is Better
ATLANTA, Sept. 28, 2007 -- A new, portable biosensor based on interferometry is more sensitive and days faster than commercially available tests for avian influenza ("bird flu"), and can also identify different strains simultaneously. “We can do real-time monitoring of...
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...
Laser Detects Viruses in Under a Minute
ATHENS, Ga., Nov. 16, 2006 -- Using a technique called surface-enhanced Raman spectroscopy, researchers have developed a way to detect viruses such as the flu and HIV in under a minute. In addition to eliminating the day or more wait for test results from a doctor's office,...
