Bruker has announced the launch of its N8 Neos Santerra micro analysis system that combines Raman spectroscopy and atomic force microscopy on a single optical microscope platform.

The judicious use of a state-of-the-art imaging method enables researchers to capture structural snapshots of complex molecules as they participate in chemical reactions, revealing the sequence of specific atomic motions that lead to chemical change. It’s thought the approach, described in Nature (doi: 10.1038/nature08527), can be used more widely to improve our understanding of important chemical transformations.

Scientists at Queen’s University Belfast are developing a Raman spectroscopy-based sensor to detect chemical agents and illegal drugs which will help in the fight against the threat of terrorist attacks. Special gel pads will be used to “swipe” an individual or crime scene to gather a sample which is then analysed by the Raman instrument that can detect the presence of chemicals within seconds. This will allow better, faster decisions to be made in response to terrorist threats.

The new DSC-Raman system from PerkinElmer combines thermal analysis with Raman spectroscopy to provide greater insight into material changes at a molecular level. It combines the double furnace DSC 8500 with the RamanStation 400 spectrometer, enabling simultaneous analysis of chemical and structural information from the spectrometer and correlating it with the calorimetric data of the DSC. Tests using the hyphenated techniques have given greater insight into polymer crystallisation, drug–carrier interactions, curing and polymorphic changes.

Renishaw has enhanced the capabilities of its inVia microscope which now offers remote system diagnosis and control of key system functions such as laser wavelength change, rapid switching between viewing modes, automated system optimisation and validation, the ability to queue multiple measurements and measurement templates that enable non-expert users to apply identical experimental conditions continuously. The microscopes now offer complete automation, remote control, large area imaging and faster operation.

Introduction

Interest in Raman spectroscopy as an analytical technique that can be applied in a wide variety of fields continues to increase. The main reason for this interest is that no special sample preparation is required. However, the Raman signal is typically very weak, with only one in every 106–108 photons being scattered. This has driven the development of several enhancement techniques, e.g. Resonance Raman (RR), Surface Enhanced Raman Spectroscopy (SERS) and Surface Enhanced Resonance Raman Spectroscopy (SERRS), which can be used for dilute samples.

The development of the Raman imaging spectrograph came from the need for combining high light throughput, distortion-free performance and polarisation-free optical design. These requirements, together with the small footprint of the device, good image quality and high spectral resolution were achieved with the fully transmissive design used in the Specim ImSpector series of imaging spectrographs, which are available for several standard wavelength ranges from 500 nm up to 1000 nm for use with different types of excitation lasers.

Renishaw has developed its Streamline Plus Raman imaging system, which combines hardware, software and firmware to improve data collection, visualisation and processing. The combination of line focus, for minimal sample damage, high-speed encoded stage and synchronised readout of the CCD detector enables images to be collected rapidly and at variable spatial resolution. There are no limits to the image area dimensions imposed by the objective field of view, therefore enabling adaptability and eliminating the need to stitch images together for large area coverage, resulting in artefact-free results. Integration of WiRE 3.1 software offers many benefits. Regions of interest are simple to set up using optical micrograph montages, experiments can be queued and chemical images can be viewed and manipulated during acquisition, whilst a suite of visualisation and chemometric tools are available to process and analyse the collected data. The software also offers additional features including full support for multiple detectors, automatic spectrometer configuration for “hands-free” excitation wavelength changes and enhanced integration tools for third party products.

Scientists at the University of Edinburgh, UK, have developed a technique using Raman spectroscopy to test the quality of sperm before it is used for in vitro fertilisation (IVF) and increase the chances of conception. Dr Alastair Elfick, lead scientist on the project, explained: “in natural conception the fittest and healthiest sperm are positively selected by the arduous journey they make to the egg. What our technology does is to replace natural selection with a DNA-based ‘quality score’.” This can then be used to decide whether the sperm is healthy enough to be used to fertilise an egg as part of the IVF treatment.

The sperm are captured in two highly focussed beams of laser light, optical tweezers, and then the DNA of an individual sperm can be analysed from its Raman spectrum. The research is currently in a pre-clinical phase, and if successful could be available to patients in the next five to ten years.

Researchers at the Humboldt-Universität zu Berlin, Germany, have reported in Analytical Chemistry (doi: 10.1021/ac801791a) an advance toward development of technology that could underpin automated, real-time systems for identifying specific kinds of plant pollen circulating in the air.

Janina Kneipp and colleagues explain that current pollen counts and allergy warnings are based on visual identification of the specific kind of pollen by examining pollen grains under a microscope. That procedure takes time, making it impossible for allergy-sufferers to know the kinds of pollen that are airborne on an hour-by-hour basis. The researchers describe using Raman spectroscopy to identify chemical structures in pollen grains that distinguish oak and maple pollen, for instance, from maple and other kinds. They obtained these chemical “signatures” for 15 different kinds of tree pollen.
