Seeing chemistry unfold inside living cells is one of the biggest challenges of modern bioimaging. Raman microscopy offers a ...

Detecting nanoscale plastic pollutants in the environment is a continuing challenge, and their presence is commonly only estimated rather than measured directly. A project at Vienna's TU Wien has now ...

The integration of O-PTIR and laser scanning technologies is advancing microplastics analysis, offering superior chemical ...

Understanding complex biological and biomedical systems is greatly aided by 3D imaging, which provides much more detailed information than traditional two-dimensional methods. However, live cell and ...

Nonlinear Raman microscopy techniques, such as coherent anti-Stokes Raman scattering and stimulated Raman scattering, are widely used to provide chemical and spatial information. A third nonlinear ...

Visualization of glucose molecule "fingerprint information". (a) SNOM-TERS platform based on fiber vector light field; Background-free tip nanofocusing light source (b) and its electric field ...

During light scattering, the majority of scattered light undergoes no change in frequency (or energy), in a process referred to as referred to as elastic or Rayleigh scattering. Raman spectroscopy ...

In this interview, Dr. Joshua Lea explores the role of the integration of Raman spectroscopy with SEM technology for advanced materials analysis. Can you introduce yourself and the topic you will be ...

Plasmonic nanogap confinement extends sum frequency vibrational spectroscopy to the nanoscale, enabling direct imaging of ...

Gisela Eckhardt was one of the early pioneers in laser physics, discovering the principle behind the Raman laser in 1962. Valdas Pasiskevicius, Richard Mildren and David Burman tell the largely ...
