05/05/2009 -- Super-sensitive rapid cancer biomarker test uses gold nanoparticles, dynamic light scattering
MAY 5, 2009--Feasibility studies of a new test for rapid cancer detection show that the test is highly sensitive, easy to use, and could enable major improvements in early cancer diagnosis. Called nanoDLSAY, it uses dynamic light scattering and gold nanoparticle probes to detect cancer biomarkers. The test shows promise for detecting other diseases and conditions as well as for research, and is expected to be commercially available beginning in three years. -
05/06/2009 -- Inexpensive optical device proves able to detect and distinguish H1N1 from other flu viruses
MAY 6, 2009--Together with the CDC, InDevR (Boulder, CO) has confirmed that its FluChip product can detect swine-origin H1N1 influenza A viruses, and distinguish them from seasonal flu and avian viruses. Less susceptible to failure than qRT-PCR assays, it will hold up as the virus evolves. InDevR will now manufacture FluChip Kits for State Public Health labs, and will combine FluChip with another technology to make the assay inexpensive and easy to use in any lab with basic PCR capabilities. -
05/07/2009 -- Laser ablation method used to treat benign prostate tumors now applied to breast tumors
MAY 7, 2009--During the recent meeting of the American Society of Breast Surgeons, a panel discussion explored the advantages of a new laser treatment for fibroadenomas, the most common form of benign breast tumor. Among the panelists was Kambiz Dowlat, M.D., professor of surgery at the Rush University Medical Center (Chicago, IL) who pioneered laser treatment of small breast tumors. -
05/08/2009 -- Optical fiber supplier OFS benefits medical applications with 25 years' experience
MAY 8, 2009--The Specialty Photonics Division of OFS today begins its 25th year of business, in Avon, CT, which is home to its medical manufacturing operations. With its research arm, OFS Laboratories, the firm invests substantially in design and production of medical-grade fibers and components such as lasers and devices for imaging, sensing, data transmission and illumination. Applications include urology, ophthalmology, orthopedics, dermatology, cardiology, angioplasty, and dentistry. -
05/11/2009 -- IR fluorescent proteins shown to enable whole-body imaging in small animals
MAY 11, 2009--Green fluorescent protein (GFP) has been critical to bioscience, but its wavelengths are not long enough to allow a living animal's inner cells to glow. Now a University of California, San Diego research team--led by Roger Tsien, who shared the 2008 Nobel Prize for GFP--reports that bacterial proteins can be engineered into infrared-fluorescent proteins (IFPs), whose wavelength can penetrate tissue and are thus suitable for whole-body imaging in small animals.
