Wide-field coherent anti-Stokes Raman scattering microscopy based on picosecond supercontinuum source

open access: yesAPL Photonics, 2018
We present a wide-field coherent anti-Stokes Raman scattering microscopy setup based on picosecond-laser-pumped supercontinuum and use it to demonstrate video-rate imaging with chemical specificity. The broadband excitation allows simultaneous imaging of

Raman Imaging of Plant Cell Walls in Sections of Cucumis sativus

open access: yesPlants, 2018
Raman microspectra combine information on chemical composition of plant tissues with spatial information. The contributions from the building blocks of the cell walls in the Raman spectra of plant tissues can vary in the microscopic sub-structures of the

Two-dimensional imaging of crystal phase and stress component by micro-Raman spectroscope equipped with integral field unit

open access: yesNihon Kikai Gakkai ronbunshu, 2018
Micro-Raman spectroscopy is used to measure phases, stresses and strains in microstructures comprising semiconductor materials, such as Si. However, the two-dimensional Raman imaging techniques for directly observing phases and measuring stresses and ...

Ultra-bright Raman dots for multiplexed optical imaging

open access: yesNature Communications, 2021
Raman-based imaging of biomarkers is often challenging due to low sensitivity. Here, the authors use a swelling-diffusion approach to develop a series of Raman probes that are both ultra-bright and compact in size, and demonstrate multiplexed imaging of ...

Surface-enhanced Raman nanoparticles for tumor theranostics applications

open access: yesActa Pharmaceutica Sinica B, 2018
Raman spectroscopy, amplified by surface-enhanced Raman scattering (SERS) nanoparticles, can provide an in vivo imaging modality due to its high molecular specificity, high sensitivity, and negligible autofluorescence.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Duplex Stainless Steel Laser‐Surface Textured: Stability in Brine Solution

open access: yesAdvanced Engineering Materials, EarlyView.
Controlled laser‐surface treatment (LST) of duplex DSS2205 steel is performed to increase its stability in brine solution under cyclic electrochemical assays. The superior protection with respect to flat and smooth panels is attributed to the presence of FeCr2O4 as the main protective oxide layer in the LST surface, after corrosion tests. The stability

Identification of microplastic fibres released from COVID-19 test swabs with Raman imaging

open access: yesEnvironmental Sciences Europe, 2023
Background COVID-19 pandemic is not yet over, and it has been generating lots of plastic wastes that become a big concern. To catch the virus, for example, no matter via antigen or PCR test, swab is generally used for sampling.
