Engineered Plasmonic and Fluorescent Nanomaterials for Biosensing, Motion, Imaging, and Therapeutic Applications

open access: yesAdvanced Materials, EarlyView.
A schematic illustration of how noble metals can be used to create nanoparticles (NPs) or nanoclusters (NCs). Noble metal NPs, due to their plasmonic properties, enable photothermal therapy and surface‐enhanced Raman scattering (SERS). In contrast, NCs, which lack a plasmonic resonance band, exhibit fluorescence, making them ideal for bioimaging ...

Spatiotemporally Resolved Orbital Hall Effect in a Topological Semimetal

open access: yesAdvanced Materials, EarlyView.
Real‐space mapping of orbital angular momentum (OAM) transport is achieved using contact‐free polarimetric terahertz spectroscopy. This principle is applied to the topological semimetal Td‐WTe2, revealing the spatial separation of electrons into two distinct regions characterized by opposite out‐of‐plane OAM (±Lz).

Direct Laser Writing of Polymer Nanocomposites for Tunable Structural Color

open access: yesAdvanced Materials, EarlyView.
Herein, direct laser writing is used to polymerize self‐assembled nanocomposite materials. Using fabrication parameters, the interparticle spacing is finely tuned beyond the thermodynamically stable state. This is exploited to generate wide gamut structural color in water.
