Pittcon 2011: the Editors Gold Award Goes to WITec
The Editors Choice Awards honors the most significant and important technological advancement introduced at the Pittcon conference and technical exhibition (14.-17.March 2011, Atlanta, USA). This year 27 different products were nominated by a panel of more than 150 editors. more
Horiba Scientific Announces the XploRA INV Raman Microscope
Horiba Scientific has launched the XploRA INV, which combines the automation features and small footprint of the standard XploRA confocal Raman microscope with the capabilities of an inverted microscope, especially important for demanding biological applications. more
WITec Anounces the Winner of the Paper Award 2010
WITec announced the winner of the WITec Paper Award 2010. The award goes to Konrad Meister, Diedrich Schmidt, Erik Bründermann and Martina Havenith from Ruhr-University Bochum as authors of the paper: "Confocal Raman microspectroscopy as an analytical tool to assess the mitochondrial status in human spermatozoa" (Analyst, 2010, 135, 1370 - 1374). The paper was submitted by Dr. Diedrich Schmidt who will additionally receive a 500 Euro Amazon Gift card. more
True Surface Microscopy
Surface Topography With High Precision: WITec has launched the True Surface Microscopy option. The core element of this imaging mode is an integrated sensor for optical profilometry. Large-area topographic coordinates from the profilometer measurement can be precisely correlated with the large-area confocal Raman imaging data. more
Surface-Enhanced Raman Spectroscopy
Laboratory researchers may have found a way to improve Raman spectroscopy as a tool for identifying substances in extremely low concentrations. Potential applications for Raman spectroscopy include medical diagnosis, drug/chemical development, forensics and highly portable detection systems for national security. The ability to identify molecules at low concentrations with great specificity and provide non-invasive, nondestructive measurements has led to the increasing use of Raman spectroscopy as an accepted analytical technique. moreOct. 29, 2010How Graphene Nanotubes Interact
In awarding this year's Nobel Prize in Physics, the Nobel Prize Committee referred to graphene as a material with exceptional properties and huge potential for fabricating new materials and manufacturing innovative electronics. When a layer of graphene is rolled up to a seemless cylinder, a carbon nanotube is formed. The young investigators group of Dr Carola Meyer studied what happens if several of these tubes stick into each other. more
Multiwavelength Raman Microscope
BaySpec announced the latest addition to the growing line of Raman instrumentation: the Nomadic Multiwavelength Raman Microscope. This Microscope is the only Raman microscope on the market today that is simultaneously equipped with three excitation sources (532, 785, and 1064 nm). The dedicated spectrographs and detectors for each excitation wavelength ensures optimal spectral coverage, resolution, and sensitivity, with no trade-offs or compromises. more
A Confocal Raman Imaging Study on Emulsions
In the life sciences and bio-medical research, in the food as well pharmaceutical industry the development of characteristic emulsions and suspensions with distinctive features play an important role. As the microstructure of such mixtures strongly determines the properties of final products, powerful analytical tools are required for studying the distribution of the various compounds. more
Ultrafast Confocal Raman Imaging
In Confocal Raman imaging the acquisition time for one Raman spectrum is a crucial value, as it influences the acquisition time of the image which typically consists of tens of thousands of Raman spectra. This article describes how the use of a spectroscopic EMCCD as the detector can significantly reduce the acquisition time down to a few milliseconds per spectrum, as well as tremendously improve sensitivity. more
Tip-enhanced Raman Spectroscopy and Imaging
A possibility to not only visualize but to locally probe a chemical structure, composition, conformational state and stresses on the nanoscale has stimulated the development of apertureless near-field vibrational spectroscopy and imaging with ultrahigh spatial resolution laying beyond the diffraction limit [1-3]. It has become possible due to the delocalization of evanescent waves (near-field) existing in the proximity of nano-sized objects with a sharp metal probe.more
