Event Report: 11th Confocal Raman Imaging Symposium

Many international researchers joined the 11th Confocal Raman Imaging Symposium from September 29th to October 01st 2014 in Ulm, Germany. The conference is a popular event at which the Raman community can present and discuss its latest scientific results. Talks from various fields of application and over 20 poster presentations provided a comprehensive overview of modern Raman microscopy for the 80 participants. Another conference highlight was the presentation of the new Raman and Scanning Electron Microscope RISE.

Molecular Movies for Calcium Ion Imaging

Fluorescent proteins have revolutionized molecular and cellular biology by offering the genetically encodable and versatile biosensors to image life processes. However, the fluorescence mechanisms of these biosensors remains elusive. Using femtosecond stimulated Raman spectroscopy, we reveal the structural dynamics basis of a new calcium ion (Ca2+) biosensor by capturing images of one of the fastest chemical reactions in proteins, namely, excited state proton transfer, starting from time zero.

3D Raman Images: Large-Area Data Acquistion and Processing

Confocal Raman Microscopy is a high-resolution imaging technique that has become widely used for the characterization of materials and specimens in terms of their chemical composition. With 2D and 3D Raman images, information regarding the chemical compounds and their distribution wihtin the sample can be illustrated clearly. Newly developed software solutions for data acquisition, evaluation, and processing support the management and visualization of even large Raman data sets while providing usability for all experience levels and requirements [1,2,3]. more

Horiba LabRAM HR Evolution: Raman Imaging of Low Frequency Bands

There are two methods to determine the number of layers of nano-materials like Graphene or Molybdenum disulfide (MoS2) with Raman spectroscopy: Measuring the intralayer vibrational modes (fingerprint spectral region) and measuring the interlayer modes (very low frequencies region).

Tip-Enhanced Raman Imaging of Individual Carbon Nanotubes

Carbon nanotubes are expected to be used in a myriad of applications ranging from military protective clothing to hydrogen storage. Due to their nanometer dimensions, however, the structure and surface chemistry of individual carbon nanotubes cannot be easily studied using conventional techniques. Norihiko Hayazawa and colleagues from the Near Field NanoPhotonics Research Team at the RIKEN Center for Advanced Photonics have now developed a high-resolution microscopy technique that can resolve individual carbon nanotubes under ambient conditions. The work has been published in Nature Communications.

Toptica IntroducesTopMode

Toptica´s TopMode is a high-coherence, high-power diode laser which operates as easily as a HeNe-laser.
The proprietary CoHerence-Advanced Regulation Method (CHARM) provides active stabilization of the lasers' coherence and ensures continuous single-frequency operation for excellent stability of lasing wavelength and output power. Featuring a spectral width of less than 5 MHz (a coherence length greater than 20 m), the TopMode is available at six wavelengths from 405 nm to 685 nm. more

Amplifying the Sensitivity of Raman Spectroscopy Using Carbon Nanotubes Probes

Using carbon nanotubes, a research team led by Professor Hyung Gyu Park in collaboration with Dr. Tiziana Bond has developed a sensor that greatly amplifies the sensitivity of commonly used but typically weak vibrational spectroscopic methods, such as Raman spectroscopy. This type of sensor makes it possible to detect molecules present in the tiniest of concentrations.
