Highly Sensitive Coherent Anti-Stokes Raman Scattering Imaging of Protein Crystals.

چکیده
Serial crystallography at last generation X-ray synchrotron sources and free electron lasers enabled data collection with micrometer and even submicrometer size crystals, which have resulted in amazing progress in structural biology. However, imaging of small crystals, which although is highly demanded, remains a challenge, especially in the case of membrane protein crystals. Here we describe a new extremely sensitive method of the imaging of protein crystals that is based on coherent anti-Stokes Raman scattering.

Coherent anti-Stokes Raman scattering polarized microscopy of three-dimensional director structures in liquid crystals
We demonstrate three-dimensional vibrational imaging of director structures in liquid crystals using coherent anti-Stokes Raman scattering sCARSd polarized microscopy. Spatial mapping of the structures is based on sensitivity of a polarized CARS signal to the orientation of anisotropic molecules in liquid crystals. As an example, we study structures in a smectic material and demonstrate that si...
متن کاملHighly Selective Standoff Detection and Imaging of Trace Chemicals in a Complex Background using Single-Beam Coherent Anti-Stokes Raman Spectroscopy
A sensitive, non-destructive and highly selective method of standoff detection using coherent anti-Stokes Raman spectroscopy (CARS) is presented. The approach uses a single amplified femtosecond laser to generate high resolution (<10cm) multiplex CARS spectra encompassing the fingerprint region (400cm – 2500cm) at standoff distance. Quantitative studies of this method result in detection of 2μg...
متن کاملBroadband Coherent Anti-Stokes Raman Scattering
Broadband coherent anti-Stokes Raman scattering (BCARS) microspectroscopy is a unique label-free imaging modality that provides detailed chemical information at each pixel. In minutes, this technique captures a “hyperspectral” cube that co-registers microscopic spatial features with chemical signatures, sensitive to molecular content and structure. This technique can delve into the molecular in...

Liquid crystals are a class of industrially important materials whose optical properties make them useful particularly in display technology. Optical imaging of these materials provides information about their structure and physical properties. Coherent anti-Stokes Raman scattering (CARS) microscopy is used to provide three-dimensional chemical maps of liquid crystalline samples without the use...
متن کاملMultiplex Coherent Anti-Stokes Raman Scattering Microspectroscopy and Study of Lipid Vesicles
We report a theoretical description and experimental implementation of multiplex coherent anti-Stokes Raman scattering (M-CARS) microspectroscopy using a picosecond pump beam and a femtosecond Stokes beam. The effect of the chirp in the Stokes pulse on a M-CARS spectrum is studied. Polarization-sensitive detection is utilized for suppression of the nonresonant background and for selective detec...
