UV-Vis spectroscopy is routinely used in analytical science in part because it is a simple way of studying a sample’s optical properties over the UV and visible regions of the electromagnetic spectrum. Here, we used the DS5 UV-Vis Spectrophotometer to study the unique and interesting effects that occur when gold nanoparticles interact with light. Read to find out more.

Photoredox catalysis is a powerful approach that uses light to unlock new molecular synthesis pathways. Light excites a photosensitiser molecule which transfers an electron to the substrate molecule. The resulting pair of radicals can then recombine or escape their solvent cage to generate reaction products. Understanding the mechanism of the reaction is essential to optimise its conditions and maximise its yield. This is what Dr Troian-Gautier’s team set out to do, using a combination of different reaction schemes and spectroscopic techniques. Find out more.

Surface-enhanced resonance Raman scattering (SERRS) is a technique that offers unparalleled sensitivity and specificity in spectroscopic detection and is promising for many applications in analytical research. In this new Application Note, we use the DS5 UV-Vis Dual Beam Spectrophotometer and RM5 Raman Microscope to demonstrate that the optical response of SERRS nanosensors contains combined SERS and RRS effects.

Optical probes based on lanthanide complexes are of particular interest in the biomedical field and life sciences due to their unique magnetic and photoluminescent properties. In this application note, an Edinburgh Instruments FS5 Spectrofluorometer is used for a complete characterisation of the lanthanide-based optical probes.

In this application note, the transition-metal dichalcogenide molybdenum disuflide (MoS2) is characterised using the RM5 Confocal Microscope with Raman and photoluminescence imaging to characterise its layer-dependent optoelectronic properties.

Surfaced enhanced Raman scattering (SERS) is a great technique to enhance the Raman scatter from a sample. One application SERS is well suited to is testing for the presence of pesticides on apple skin. This is important for keeping produce safe for consumptions, as well as monitoring the environmental impact of using pesticides.

Raman spectroscopy is a powerful tool for chemical analysis, but it is susceptible to fluorescence interference from the sample that decreases the quality of data. In this latest technical note, we discuss different methods for reducing fluorescence in Raman spectroscopy.

This Fluoracle® Software Highlight demonstrates the use of SC-41 Plate Reader sample module with the FS5 Spectrofluorometer. The SC-41 allows automatic spectral and lifetime measurements of multi-well plates to be easily acquired.

In this application note, the transition-metal dichalcogenide tungsten diselenide (WSe2) is characterised using the RMS1000 Confocal Microscope with five imaging modalities: reflected brightfield & darkfield, Raman, photoluminescence and second harmonic generation to fully characterise its layer-dependent optoelectronic properties. The multimodal capabilities of the RMS1000 Confocal Microscope make it an ideal imaging platform for studying the optoelectronic properties of transition-metal dichalcogenides.

This Technical Note demonstrates the use of SC-41 Plate Reader sample module with the FS5 Spectrofluorometer. The SC-41 allows automatic measurements of multi-well plates to be easily acquired, in this case the SC-41 was used in combination with the Trend Analysis feature of Fluoracle for ratio analysis.
