Automated Imaging of Cultured Bacteria in Picoliter Droplets by Coherent Anti‐Stokes Raman Scattering and Two‐Photon Excited Fluorescence Microscopy

Journal of Raman Spectroscopy, EarlyView.
We present an automated system that combines an image‐based fuzzy logic controller for precise positioning of microfluidic picoliter droplets with nonlinear microscopy, using CARS and TPEF modalities for detailed analysis of droplet composition. Time series and z‐stack images of E. coli, B. subtilis, and M. arborescens were recorded.

Identification of Natural and Artificial Modifications in DNA at the Nanometer Level

Journal of Raman Spectroscopy, EarlyView.
Short single‐ and double‐stranded DNA sequences with natural and artificial markers are examined at ambient conditions using TERS to identify and localize the labelled nucleobases. The differences between single‐ and double‐stranded DNA should provide clear experimental evidence of the extreme surface sensitivity of TERS.

Reusable SERS Substrate Based on AuNP/PS‐b‐P2VP Nanocomposites With Photocatalytic Activity

Journal of Raman Spectroscopy, EarlyView.
We developed a bifunctional SERS substrate by assembling AuNPs on PS‐b‐P2VP thin films, capable of both sensitive molecular detection and UV‐assisted self‐cleaning. The platform demonstrates excellent reusability over four adsorption–degradation cycles, driven by a hot‐hole‐mediated photocatalytic mechanism without semiconductors.

Reliable Estimation of Wavenumbers for Calcite Peaks

Journal of Raman Spectroscopy, EarlyView.
The wavenumbers of the calcite peaks were accurately estimated using a combination of a He–Ne laser and Ne emission lines. The values following the ± symbol represent the expanded uncertainties, corresponding to an approximate 95% confidence interval.
