BIRMINGHAM, N.J., July 31 /PRNewswire/ -- Photon Technology International (PTI), a known innovator in fluorescence with over 26 years of experience is once again expanding the frontiers of detection to attomolar levels with its new QuantaMaster(TM) 40 Spectrofluorometer. While typical spectrofluorometers struggle with picomolar (10(-12))( )detection, which is already a very tiny amount, the new PTI system can now detect attomolar (10(-18)) amounts, allowing it to detect six orders of...

Researchers at the Helmholtz Zentrum Mnchen and the Technische Universität Mnchen are using a combination of light and ultrasound to visualize fluorescent proteins that are seated several centimeters deep into living tissue. In the past, even modern technologies have failed to produce high-resolution fluorescence images from this depth because of the strong scattering of light. In the Nature Photonics journal, the Munich researchers describe how they can reveal genetic expression within...

A Vanderbilt chemist and a biomedical engineer have teamed up to develop a respiratory virus detector that is sensitive enough to detect an infection at an early stage, takes only a few minutes to return a result and is simple enough to be performed in a pediatrician's office.Writing in The Analyst "“ a journal published by the Royal Society of Chemistry "“ the developers report that their technique, which uses DNA hairpins attached to gold filaments, can detect the presence of...

The more dots there are, the more accurate a picture you get when you connect them. A new imaging technology could give scientists the ability to simultaneously measure as many as 100 or more distinct features in or on a single cell. In a disease such as cancer, that capability would provide a much better picture of what's going on in individual tumor cells.A Stanford University School of Medicine team led by Cathy Shachaf, PhD, an instructor in microbiology and immunology, has for the first...

A team of Vanderbilt scientists have invented the world's smallest version of the periscope and are using it to look at cells and other micro-organisms from several sides at once. "With an off-the-shelf laboratory microscope you only see cells from one side, the top," says team member Chris Janetopoulos, assistant professor of biological sciences. "Not only can we see the tops of cells, we can view their sides as well "“ something biologists almost never see." The researchers have...

Oral human papillomavirus can be detected using a VELscope, a device used by dentists to harden cavity fillings, U.S. researchers said. Study author John C. Comisi said he discovered that the blue light emitted by the VELscope also detects cancerous oral tissue. The study explains that when emitting a specific wavelength of light into the mouth, oral fluorescence occurs, which in turn causes the tissue to emit its own light -- called natural fluorescence. The VELscope produces a blue light...

This year's model isn't your father's nanocar. It runs cool.The drivers of Rice University's nanocars were surprised to find modified versions of their creation have the ability to roll at room temperature. While practical applications for the tiny machines may be years away, the breakthrough suggests they'll be easier to adapt to a wider range of uses than the originals, which had to be heated to 200 degrees Celsius before they could move across a surface.The nanocar was a sensation when...
