Beads‐on‐a‐Tip testing for ultrasensitive antigen detection across a large dynamic range

Smart Molecules, EarlyView.
Non‐specific adsorption on nitrocellulose membranes limits the sensitivity of conventional lateral flow immunoassays. Here, we present a Beads‐on‐a‐Tip immunoassay that replaces the membrane with magnetic beads for antigen capture and enrichment, while employing upconversion nanoparticles as background‐free luminescent reporters.

Selective Wettability–Driven Evaporation‐Enhanced Redox Cycling for Robust and Ultrasensitive Detection of Viral Particles

Small Methods, EarlyView.
ABSTRACT Timely detection of viral infections, particularly in settings outside centralized laboratories, is essential for controlling outbreaks. Small electrochemical biosensors are appealing because they are fast, require microliter sample volumes, and can be integrated into portable devices.

Sphinganine‐phosphate prevents influenza infection via promoting CD8+ T cells proliferation and activation

VIEW, EarlyView.
This study established clinical cohorts of respiratory viral infections and identified sphinganine‐phosphate (SA) as a metabolite significantly upregulated post‐infection through metabolomic analysis. In vitro and in vivo experiments demonstrated that SA promotes the generation of effector CD8+ T cells via the SOCS1/JAK1/STAT1 pathway, which ...
