An Amplification-Free Digital Assay Based on Primer Exchange Reaction-Mediated Botryoidal-Like Fluorescent Polystyrene Dots to Detect Multiple Pathogenic Bacteria

ACS Nano, Journal Year: 2024, Volume and Issue: 18(45), P. 31174 - 31187

Published: Nov. 1, 2024

Multiple and ultrasensitive detection of pathogenic bacteria is critical but remains a challenge. Here, we introduce digital assay for multiplexed target DNA amplification-free using botryoidal-like fluorescent polystyrene dots (PS-dots), which were first prepared through the hybridization reaction between primer exchange chains nanospheres that encapsulated polymer signal preamplification. The bacteria's was cleavaged by argonaute (Ago) protein-mediated multiple precise cleavage reactions, where obtained sequences bridged magnetic beads (MBs) PS-dots via reaction, MB-botryoidal PS-dot complexes utilized as probes based on colors sizes encoding. An artificial-intelligence-fluorescent microsphere counting algorithm applied to identify count MBs readout. This combined ultrabright with

Wheat Germ Agglutinin‐Modified “Three‐in‐One” Multifunctional Probe Driven Broad‐Spectrum and Flexible Immunochromatographic Diagnosis of viruses With High Sensitivity

Small, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 22, 2024

Abstract The conventional lateral flow assay (LFA) fails to the demands for accurate screening of viruses as a result its low sensitivity colorimetric signal output and poor universality limited by antibody pairs. Here, magnetically assisted dual‐signal LFA platform is developed ultrasensitive, universal, flexible detection viruses. A “three‐in‐one” multifunctional probe (MAuDQD) prepared using 180 nm Fe 3 O 4 core load numerous Au nanoparticles (NPs) two layers QDs, which can substantially improve through coupling with effects magnetic enrichment colorimetric/fluorescent enhancement. Wheat germ agglutinin (WGA)‐modified MAuDQD attained broad‐spectrum capture viral membrane proteins dual‐mode severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) monkeypox virus (MPXV) on strip. In mode, target detected directly, visual reaching 0.1–0.5 ng mL −1 fluorescent mode supported quantitative analysis SARS‐CoV‐2/MPXV limits decreasing pg level. Practicability MAuDQD@WGA‐LFA verified 33 real clinical samples, showing proposed has great potential become sensitive, accurate, universal tool on‐site monitoring infections.
