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 ...

Revisiting Ferroelectric‐Gated Phototransistors: A Tripartite Synapse‐Inspired Approach to In‐Sensor Image Processing

open access: yesAdvanced Materials, EarlyView.
A ferroelectric‐gated phototransistor (FGPT) enables linear and multilevel modulation of photoconductance through partial polarization switching and photogating effects. The device achieves photonic non‐volatility over a 153 dB dynamic range and performs in‐sensor processing under unstructured illumination, demonstrating enhanced face recognition ...

Dual‐Selective Terahertz‐Nanodisc Metasurfaces for Exploring Neurotransmitter Dynamics beyond Spectral Limitations

open access: yesAdvanced Materials, EarlyView.
Observation and detection of neurotransmitter dynamics in aqueous system has been hurdle for analytical fields due to its weak and reversible nature. A terahertz‐nanodisc metasurface which implements comprehensive detection over conformational change and selective sensing is introduced. Utilizing the THz regime photonics and biomimetic environment with

Automated Transcranial Photobiomodulation in Healthy Rats: Effects on Working Memory and Brain Markers

open access: yesAdvanced Therapeutics, EarlyView.
Transcranial photobiomodulation (PBM) enhances spatial working memory in healthy rats under both continuous and alternating stimulation protocols. At the neural level, PBM modulates cytochrome c oxidase activity, increases prefrontal and hippocampal synaptic markers, and induces region‐specific c‐Fos expression. These effects suggest improved cognitive

Dopamine D2 antagonist-induced striatal Nur77 expression requires activation of mGlu5 receptors by cortical afferents

open access: yesFrontiers in Pharmacology, 2012
Dopamine D2 receptor antagonists modulate gene transcription in the striatum. However, the molecular mechanism underlying this effect remains elusive. Here we used the expression of Nur77, a transcription factor of the orphan nuclear receptor family, as ...

Physics of Selective Targeting of Cancer Cells by Magnetoelectric Nanoparticles: Exploring the Role of Conductivity and Capacitance in Tumor‐Specific Attraction

open access: yesAdvanced Theory and Simulations, EarlyView.
Magnetoelectric nanoparticles exploit cancer cells' electrical vulnerabilities—altered membrane charge and higher capacitance—to achieve tumor‐specific targeting without bioreagents. MATLAB simulations reveal how electromagnetic forces create targeting specificity, while external magnetic fields enhance precision. This may enable wirelessly controlled,
