Red-emissive carbon nanostructure-anchored molecularly imprinted Er-BTC MOF: a biosensor for visual anthrax monitoring

Abstract

Investigating effective fluorescence strategies for real-time monitoring of dipicolinic acid (DPA) is of paramount importance in safeguarding human health. Herein, we present the design of a desirable red emissive carbon...

A dual‐responsive luminescent sensor for efficient detection of 3‐nitrotyrosine and dipicolinic acid biomarkers based on copper(II) organic framework

“…Additionally, the intrinsic relationship between the DPA concentrations and the luminescence intensities of CuMOF suspensions was investigated. As shown in Figure 7c, it is evident that within the low concentration ranges, there exist favorable linear correlations aligning closely with the equation of I/I 0 = 18,770[DPA] + 1.1254 (K sv = 1.87 Â 10 4 M À1 , R 2 = 0.9675, LOD = 85.2 ng/ml), higher than other reported ones [53][54][55][56][57] (Table 3). Meanwhile, the response time was also conducted, and the results are shown in Figure S12, indicating the luminescence intensity of CuMOF suspensions can be maintained stable after 30 s. Furthermore, the CuMOF exhibits notable antiinterference capabilities when detecting the DPA biomarker amidst the presence of other interfering analytes (Figure S13).…”

Enhancing On-Skin Analysis: A Microfluidic Device and Smartphone Imaging Module for Real-Time Quantitative Detection of Multianalytes in Sweat

“…Additionally, to ascertain the binding constant ( K b ) and the quenching efficacy of Fe 3+ ions, Fe 3+ ions, TA, and PO 4 3– ions upon interaction with CPD1, CPD2, CPD2, and CPD3, respectively, the formula log­( F 0 – F / F ) = log K b + n log­[Q] was utilized. Here, n denotes the number of interacting sites, [Q] signifies the quencher’s concentration, F 0 represents the fluorescence intensity without the quencher, and F is the fluorescence intensity in the quencher’s presence . The computed K b values were established as 2.81 1/mM, 2.69 1/mM, 4.26 1/mM, and 2.63 1/mM for Fe 3+ ions, Fe 3+ ions, TA, and PO 4 3– ions, respectively (Figure S8c,g,k,o).…”

“…Herein, we introduce a highly portable four-channel skin-interfaced soft microfluidic device that allows simultaneous sweat sampling and fluorometric sensing of potential kidney disease biomarkers including l -Tyr, l -Trp, Crt, and NH 4 + . The as-design device seamlessly integrates with smartphones, enabling convenient data retrieval and analysis . The sensing array utilizes a novel fluorometric solid-state mechanism with CPDs derived from dopamine, catechol, and o -phenylenediamine monomers embedded in the gelatin hydrogel.…”
