Magnetic Particle‐Based Thin‐Channel Analysis for Separation and Bioanalysis: From SPLITT Fractionation to Immunoassays

open access: yesJournal of the Chinese Chemical Society, EarlyView.
Thin‐channel magnetic analytical platforms integrate magnetically controlled transport with confined laminar flow to enable quantitative bioanalysis. By coupling field‐induced migration with outlet fractionation, particle deposition, or affinity capture, these platforms merge SPLITT separation, magnetophoresis, and magnetic immunoassays.

Impact of cold plasma pretreatment and hybrid infrared—hot air drying on bioactive compounds, antioxidant activity, colorimetric attributes, and texture of red beet

open access: yesJSFA reports, EarlyView.
Abstract Background Drying is essential for food preservation, yet conventional methods often compromise product quality. This study investigated the effects of cold plasma pretreatment time (0, 15, and 30 s) and an intermittent infrared‐hot air hybrid dryer (300, 600, and 900 W; pulse ratios 1 and 2) on the functional and quality attributes of dried ...

A Complex‐Frequency Framework for Kerker Unidirectionality in Photonic Resonators

open access: yesLaser &Photonics Reviews, EarlyView.
ABSTRACT Electromagnetic scattering exhibits various anomalous behaviors, such as forward or backward scattering effects known as the Kerker conditions. These anomalies appear in non‐Hermitian photonic resonators and are mathematically described by operators with complex eigenfrequencies.

Revealing the Resonant Physics of Open Photonic Time Crystals

open access: yesLaser &Photonics Reviews, EarlyView.
ABSTRACT Photonic time crystals (PTCs) are media whose permittivity is modulated periodically in time, enabling momentum bandgaps and parametric amplification of light. Their realization at the nanoscale can revolutionize the study of light‐matter interactions.

Extreme Optical Field Confinement and Enhancement in a Plasmonic Picopatch Within a Nanoparticle‐on‐Mirror Resonator

open access: yesLaser &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
