Colorimetric lateral flow assays (LFAs) are widely used for detecting analytes through color changes displayed by conjugates on a test strip, typically made of materials such as nitrocellulose (NC) membranes. However, significant number conjugate nanoparticles become trapped within the membrane's porous structure, preventing full display information. Here, gelation NC membrane is achieved introducing dimethyl sulfoxide (DMSO) into an LFA resulting in structural and high transparency membrane, exposing red-colored Au transparent portable DMSO/NC membrane. Under optimized conditions (16 μL 50 vol % DMSO water heating strip at 80 °C 8 min), becomes highly transparent, achieving 77.42% transmittance while maintaining its capability to effectively perform LFAs cardiac troponin I (cTnI) both buffer solutions clinical samples. We anticipate that this method holds promise advancing fundamental studies has potential applications healthcare environmental monitoring.

The successful application of fluorescence immunoassays for clinical diagnosis requires stable photoluminescent materials and highly efficient signal amplification strategies. In this work, the magnetism-functionalized lanthanide MOF-on-MOF (Fe3O4@SiO2@MOF-on-MOF) was synthesized through intermolecular (van der Waals) interaction-assisted growth further homogeneous epitaxial growth, which significantly improved performances uncovered underlying mechanism. quantum chemical theory calculation experimental studies revealed that introduced magnetic Fe3O4@SiO2 not only endowed separation capability but also promoted performances, increased energy transfer intersystem crossing process suppressed luminescence ligands aggregation-induced quenching. Furthermore, plasmonic Ag/Au nanocages were developed as quenchers to improve sensitivity immunoassay. On basis proposed differential (DSA) strategy, immunoassay displayed superior detection ability, with a limit 0.13 pg·mL–1 severe acute respiratory syndrome coronavirus 2 nucleocapsid protein. designed DSA strategy give new insights into ultrasensitive immunoassays.
