Self‐Assembled Physical Unclonable Function Labels Based on Plasmonic Coupling

open access: yesAdvanced Optical Materials, EarlyView.
This article introduces advanced anti‐counterfeit labels crafted through DNA‐guided self‐assembly of plasmonic nanoparticles. Utilizing nanosphere lithography for dense and precise nanoparticle placement, these labels feature unique, unclonable optical signatures achieved through plasmonic coupling, detectable by an economical 3D‐printed dark field ...

Investigating the Potential for Label‐Free Detection of Cell Apoptosis through Terahertz Nano‐Metasurfaces

open access: yesAdvanced Photonics Research, EarlyView.
This study demonstrates a label‐free optical method to monitor cells using a terahertz metasurface‐based biosensing platform. The obtained terahertz signal change for the cell‐contained nanoslots before and after external stimulus is analyzed in terms of transmittance and frequency shift, dynamically representing the cell apoptosis process.

Low‐Loss Parowax‐Imprinted Diffractive Neural Network for Orbital Angular Momentum Terahertz Holographic Imaging

open access: yesAdvanced Photonics Research, EarlyView.
This work introduces a low‐loss diffractive neural network, fabricated using an imprinting technique with parowax material, for recognizing and manipulating the topological charge of orbital angular momentum (OAM) waves. It is also demonstrated that the low‐loss diffractive network can perform mathematical operations based on the topological charges of
