Efficient identification of drug candidatesThe search for new therapeutic agents is time-consuming and expensive. Pharmaceutical companies may have to screen thousands of compounds for the ability to bind a target molecule before they hit upon a promising drug candidate. A group of Biophysicists at LMU Munich led by Professor Dieter Braun, a member of the Cluster of Excellence "Nanosystems Initiative Munich" (NIM), and a partner in NanoTemper (an LMU spin-off), have now developed a...

BIRMINGHAM, N.J., Oct. 30 /PRNewswire/ -- In the October 22nd issue of Nature Magazine, the world's foremost weekly scientific journal and flagship journal for Nature Publishing Group (NPG), recently included the EasyRatioPro as part of its feature "A Brave New Image, Advancing Fluorescence Imaging (fluorescence/Imaging - product focus)". The EasyRatioPro(TM) system is the most comprehensive instrument of its kind. Manufactured by Photon Technology International (PTI) the EasyRatioPro(TM)...

A team of Harvard chemists led by X. Sunney Xie has developed a new microscopic technique for seeing, in color, molecules with undetectable fluorescence. The room-temperature technique allows researchers to identify previously unseen molecules in living organisms and offers broad applications in biomedical imaging and research.The scientists' results are published in the Oct. 22 issue of Nature. Partial funding for the project was provided by the National Science Foundation (NSF).Fluorescence...

BIRMINGHAM, N.J., Oct. 23 /PRNewswire/ -- For researchers, innovators and scientists alike Google Scholar(TM) has proven to be a great resource for those interested in fluorescence technology. Photon Technology International (PTI), a known innovator in fluorescence for over 26 years is mentioned in over 5,400 reference papers on various applications within the site. Many of the applications are specific to Medical Research, Chemistry, Biology, Environmental Science, Materials Research and...

An innovative technique called L.I.F.E. imaging used successfully to detect bacteria in frozen Antarctic lakes could have exciting implications for demonstrating signs of life in the polar regions of Mars, according to an article published in the current issue of Astrobiology, a peer-reviewed journal published by Mary Ann Liebert, Inc. The article is available free online at www.liebertpub.com/astMichael Storrie-Lombardi, PhD, from Kinohi Institute (Pasadena, CA), and Birgit Sattler, PhD,...

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 München and the Technische Universität München 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...

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 laboratory « Structure - Activité of Normal & Pathologic Biomolecules"“ SANPB », Inserm / UEVE U829 (Genopole Evry, France) in collaboration with the Material Centre of Mines-ParisTech (Evry, France), the NRG - UMR 5060 CNRS / UTBM (Technology University of Belfort-Montbéliard) and the Physic Institute of Stuttgart University (Germany) discovered a novel route to fabricate fluorescent nanoparticles from diamond microcrystals. Results are published in Nanotechnology...

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...
