Confinement‐Enhanced Ultrabright AIE Nanoparticles With Broad Emission for Ultrasensitive Lateral Flow Immunoassay

Aggregate
Fluorescent lateral flow immunoassay (LFIA) has emerged as a critical point‐of‐care (POC) diagnostic platform for in vitro diagnosis. However, the analytical sensitivity of conventional fluorescent LFIA is constrained by the suboptimal quantum yield (QY)

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.
