A study recently conducted at the circular dichroism beamline (B23) at Diamond Light Source could pave the way for a new forensic DNA profiling technique.
New xenon lamp powered fluorescence spectrometers have been introduced by PerkinElmer.
The Duetta from Horiba Scientific is a new two-in-one fluorescence and absorbance spectrometer aimed at the mid-market.
Horiba Scientific has patented a new technique for molecular fingerprinting, A-TEEM™ (Absorbance and Transmission Excitation Emission Matrix), which simultaneously measures absorbance and fluorescence transmission.
Dmitry Gakamsky and Anna Gakamsky describe how fluorescence may be used to diagnose cataracts in human eye lenses. Further, it may also be able to grade cataracts and monitor the disease’s progress, which may help discover metabolic and ambient factors that influence the progress of the disease.
The FLIMbee galvo scanner add-on provides flexibility in scanning speed paired with positioning accuracy and sensitivity for time-resolved microscopy.
Picoquant have introduced two new models from the PMA Hybrid Series, covering broad spectral ranges with high detection efficiency.
Salmon is one of the most popular edible fish of all. Shops sell fish caught in the wild, but their main produce is salmon from breeding farms, the effluent from which can pollute rivers, lakes and oceans. German and Chilean scientists have used fluorescence measurements, high-resolution mass spectrometry and nuclear magnetic resonance spectroscopy to answer this question.
Diamond Light Source has welcomed the first users to the hard X-ray nanoprobe beamline (I14), the latest phase III beamline to be opened.
HORIBA Scientific has awarded Dr Ibrahim Cissé of MIT its annual Young Fluorescence Investigator Award.
Headwall introduces the Hyperspec Chlorphyll Fluorescence sensor which collects data from 670 nm to 780nm
The CAL(AI)2DOSCOPE (Cryogenic Absorption/Luminescence Alignment Independent Alternative Intermittent Detection Optical µSCOPE) is a microspectrometer that was constructed with the aim to facilitate the correlated investigation of absorption and fluorescence emission properties of nanovolumic protein samples under modulatable actinic illumination.
Whilst the major components of food are usually non-fluorescent, many minor food components that affect its nutritive, compositional and technological quality are fluorescent. Given its sensitivity, ease of use and non-destructive nature, this makes it useful in many applications around monitoring food processing and in fundamental food research.
Horiba Scientific has added the PTI QuantaMaster 8000 to its line of spectrofluorometers with a signal-to-noise ratio of 30,000 : 1 RMS for water Raman.
Spectro Analytical Instruments have announced an upgrade of the Spectro xSort handheld X-ray fluorescence (XRF) spectrometer
Fluorescence spectroscopy has been used to study the ancient pigment, Egyptian blue.
Edinburgh Instruments have installated one of their fluorescence spectroscopy systems at the brand new Vidyasirimedhi Institute of Science and Technology (VISTEC) in Thailand.
Research from Rice University, University of California, Los Angeles (UCLA) and Kansas State University in the USA has used super-resolution microscopy and fluorescence correlation spectroscopy to characterize such nanoscale spaces in chromatography media.
Shimadzu has introduced the RF-6000 spectrofluorophotometer. By optimising the internal design, a signal-to-noise ratio of 350 : 1 is achieved, allowing for high-sensitivity analyses of a wide range of samples. As well, the speed of 3D measurements has been increased significantly. Samples in very low concentrations or in minute amounts can be analysed by making use of optional cells designed...
Combining fluorescence spectroscopy and “stochastic optical reconstruction microscopy” enables the imaging of single molecules with unprecedented spectral and spatial resolution, thus leading to the first “true-colour” super-resolution microscope.
Nano-Spectroscopy and Bio-Imaging is a free-to-attend conference in October 2015 held in Coventry, UK.
“Optical spectroscopy in therapy response monitoring: an awakening giant” by Arja Kullaa, Surya Singh, Jopi Mikkonen and Arto Koistinen looks at the important advances made by optical spectroscopy techniques, such as diffuse optical spectroscopic imaging (DOSI), Raman, diffuse reflectance and fluorescence spectroscopy, in changing how cancer is managed in patients. The ability to repeatedly...
Orthogonal spectroscopic techniques for the early developability assessment of therapeutic protein candidates” are described by Patrick Garidel, Anne Karow and Michaela Blech. Due to its cost and time implications, in the early development phase of drug discovery the use of othogonal techniques, based on different physical observables, is important for correct decision-making.
In the pharmaceutical industry, biologicals are of increasing interest due to their high therapeutic benefits. Amongst many other questions, the stability of new canditates is of great importance. Patrick Garidel describes this in “Right angle light scattering protein thermostability screening: from research to development”. The ability of this and other fluorescence-based techniques to detect...
