Illuminating Streptomyces: Raman Spectroscopy for Antibiotic Detection and Monitoring
Journal of Raman Spectroscopy, EarlyView.Raman spectroscopy provides a non‐destructive, label‐free approach for studying the chemical diversity of Streptomyces. This review presents its application from detection to chemical characterization of secondary metabolites and monitoring of biosynthetic processes.

Journal of Raman Spectroscopy, EarlyView.We apply a sharp silicon tip, typically used for atomic force microscopy (AFM), as a nanoscale probe, and collect frequency‐shifted photons resulting from Raman scattering within the sharp tip. This approach allows us to map local electromagnetic fields in various plasmonic structures and study field “hotspots” with nanometer spatial resolution ...

Journal of the Science of Food and Agriculture, EarlyView.Abstract Mycotoxins remain a persistent threat to the safety and quality of cereal grains and other agricultural products, and their impact on human health continues to raise global concerns. In many situations, the practices traditionally used to control these toxins are no longer sufficiently effective. They can be costly, difficult to implement on a

Laser &Photonics Reviews, EarlyView.A picopatch in a plasmonic nanocavity confines the electromagnetic energy to tiny effective volumes, close to 1nm3, leading to extreme electric field enhancements. Furthermore, a clear signature of strong coupling between the picopatch modes and other modes of the structure is obtained, which strongly modifies the far‐field response. ABSTRACT Plasmonic

Spatially Uniform and Defect‐Tolerant Plasmonic Responses in 3D Printed Gold Nanoparticle Assemblies
Laser &Photonics Reviews, EarlyView.We introduce 3D nanoprinting of gold nanoparticle assemblies and show that their broad optical responses remain reproducible despite structural disorder. This robustness is attributed to ensemble‐averaged plasmonic responses from many local coupling regions.
