Colored Cellulose Nanoparticles with High Stability and Easily Modified Surface for Accurate and Sensitive Multiplex Lateral Flow Assay

ACS Nano, Год журнала: 2025, Номер unknown

Опубликована: Янв. 23, 2025

Decentralized testing using multiplex lateral flow assays (mLFAs) to simultaneously detect multiple analytes can significantly enhance detection efficiency, reduce cost and time, improve analytic accuracy. However, the challenges, including monochromatic color of probe particles, interference between different test lines, reduced specificity sensitivity, severely hinder mLFAs from wide use. In this study, we prepared polydopamine (PDA)-coated dyed cellulose nanoparticles (dCNPs@P) with tunable colors as for mLFAs. Cellulose (CNPs) were synthesized uniform spheric shapes sizes. Dye molecules loaded on CNPs via a mature industrial dyeing method. The PDA shell provided reactive surface facile receptor conjugation protected dye leaking. dCNPs@P displayed higher signal intensity than gold nanoparticles. They also had stability tolerate salt varied pH. dCNP@P-based successfully applied mycotoxins in cereals determine levels inflammatory biomarkers differentiate viral bacterial infections. tests represented high accuracy more sensitive quantified was accessible by measuring intensities colorimetric or photothermal signals. Overall, study provides practical system solution based colored dCNPs@P.
