Zero Background Visualizing Phosphorescence Lateral Flow Immunoassay of Cardiac Troponin I for Rapid and Accurate Diagnosis of Myocardial Infarction

Analytical Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Фев. 8, 2025

Fluorescence lateral flow immunoassays (FL-LFIA) have attracted considerable attention in clinical diagnosis due to their outstanding merits of affordable, sensitive, on-site, and quick detection. However, they are still plagued by significant signal interference, such as autofluorescence scattered light. The development high-performance robust phosphors, i.e., label probes featuring with the character low/no optical background, remains a great challenge. Herein, we report novel visualized phosphorescence LFIA (Phos-LFIA), where composite microspheres, carbon dots (CDs) covalently embedded dendritic mesoporous silicon nanoparticles (DMSNs), were designed selected probes. obtained CDs@DMSNs revealed uniform morphologies particle sizes, well ultralong (lifetime: 1.14 s, visible for over 8 s naked eyes) room temperature (RTP) aqueous solution. As competitive nanotags, an phosphorescence-based time-gated cardiac troponin I (cTnI) without interference. fabricated Phos-LFIA test strips demonstrated zero-background applied highly sensitive cTnI detection both buffer complex serum matrix, corresponding limits (LODs) 0.19 0.21 ng/mL, respectively. For validation, proposed excellent analytical performance (sensitivity: 95.45%, specificity: 88.9%, κ value: 0.85), demonstrating its potential rapid accurate myocardial infarction. This work provided promising background-free probe FL-LFIA, it would also open opportunity developing screening platforms other targets through modifying different recognition ligands onto CDs@DMSNs.

Photoactivated room temperature phosphorescence from lignin

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Авг. 22, 2024

Sustainable photoactivated room temperature phosphorescent materials exhibit great potential but are difficult to obtain. Here, we develop by covalently attaching lignin polylactic acid, where and acid the chromophore matrix, respectively. Initially phosphorescence of is quenched residual O2. However, switched on when oxygen consumed triplet excitons under continuous UV light irradiation. As such, lifetime increases from 3.0 ms 221.1 after 20 s activation. Interestingly, again being kept an atmosphere air for 2 h in absence irradiation due diffusion into materials. Using these properties, as-developed material successfully used as a smart anti-counterfeiting logo medicine bottle information recording. Convenient sustainable (RTP) wide ranging applications Here authors RTP acid.
