Raman Spectroscopy as a Tool for Studying Polymer Phase Transitions

Semicrystalline polymers are the largest group of commercially produced plastics. Heating and cooling of these polymers between phase transitions is used industrially to shape polymers into their final product. In this application note the RMS1000, with a heated stage, is used to observe phase transitions in two polymers; polyethylene, and nylon-6.


Discrimination of Cooking Oils Using Raman Spectroscopy

Cooking oils are one of the main components of the human diet. Adulteration of extra virgin olive oil with cheaper oils is a common problem in food fraud. This application note highlights how Raman spectroscopy in combination with chemometrics can be used to identify cooking oil adulteration.


Identification of Microplastics Using Raman Spectroscopy

Microplastic pollution is a growing environmental issue. Identification is crucial for assessing their risk to the environment, wildlife, and mankind. Raman microscopy is a great tool for the identification of small microplastics. This application note explores how the RM5 Raman Microscope combined with the KnowItAll Raman database can be used to identify polymers commonly found in the Earths aquatic systems.


Temperature Dependent Triplet States of Benzophenone; Spectral and Lifetime Measurements Utilising Transient Absorption Spectroscopy

In this application note, we demonstrate how transient absorption spectroscopy and temperature-dependent measurements can be employed to investigate and understand the nature of photoexcited triplet states of a molecule.


Optimisation of SERS for Glucose Sensing

Surfaced enhanced Raman scattering (SERS) is an enhancement technique in which nanoparticles are used to provide Raman intensity enhancement. In this application note the optimisation of gold nanoparticles are investigated for the development of a SERS glucose sensor.


Mapping Triplet-to-Singlet Förster-type Intramolecular Energy Transfer Utilising Transient Absorption and Fluorescence Spectroscopy

Featured in the prominent Science Advances journal, this exceptional research into intramolecular Förster-type triplet-to-singlet energy transfer in a donor-bridge-acceptor (DBA) dyad was led by Prof. Karl Börjesson at the University of Gothenburg and team of researchers across Sweden utilising Edinburgh Instruments FLS1000 and LP980 Spectrometers.


A Luminescent Europium Hairpin for DNA Photosensing in the Visible, based on Trimetallic Bis-Intercalators

Researchers from Birmingham University have developed a new complex for DNA sensing in collaboration with Edinburgh Instruments. Find out how our FLS1000 Spectrometer was used in this research.


Research Highlight: Bioorthogonal Photocatalytic Reactions of Flavins Converting PtIV Substrates into PtII Anticancer Drugs; Photoluminescence and Transient Absorption Data

The ideal anticancer drug would be one that is effective at killing rapidly producing cells, is targeted directly to the tumour location, and is non-toxic until it reaches the diseased area. Platinum-II (PtII) based chemotherapy drugs have been life changing for many, with the most common drug, Cisplatin, providing treatment and cures for cancerous diseases in the bladder, breast, cervix, lung, ovaries, and head and neck, to name a few.


Research Highlight: Illuminating Metal-Organic Framework (MOF) Photocatalytic Solar Fuel Mechanisms; Luminescence and Transient Absorption Spectroscopy

Understanding and optimising novel materials for the next generation of fuel sources for our energy needs that are efficient, affordable, and carbon neutral is of paramount importance for generations to come. Photocatalytic materials that can harvest sunlight and generate hydrogen gas (H2) from water is highly sought after given the enormous energy released and environmentally friendly by-product of water when burning this gas for energy.

Application Note: Measuring Picosecond Fluorescence Lifetimes Using the FLS1000 Equipped with a Hybrid Photodetector

In this application note, the measurement of sub 20 picosecond lifetimes utilising the FLS1000 Photoluminescence Spectrometer equipped with a hybrid photodetector is demonstrated, and the impact that the configuration of the FLS1000 has on the minimum lifetime that can be measured is discussed.
