Investigating effective fluorescence strategies for real-time monitoring of dipicolinic acid (DPA) is paramount importance in safeguarding human health. Herein, we present the design a desirable red-emissive carbon nanostructure anchoring molecularly imprinted Er-BTC MOF as biosensor visual determination DPA. DPA biomarker Bacillus anthracis, subcategory serious infectious diseases and bioweapons. We introduce paper test strip sensitized with aforementioned nanostructure, which integrated online UV excitation smartphone digital imaging, resulting signal-off sensing platform. The proposed fluorometric paper-based demonstrates wide linear ranges (10-125 μM) LOQ LOD 4.32 1.28 μM, respectively. designed platform exhibits impressive emission properties adaptable surface functional groups, confirm its selective capabilities against other biological molecules isomers. As proof concept, successfully applied to real samples tap water urine. This nano-biosensor, coupled signal recording, holds great promise state-of-the-art practical applications including fluorometric/colorimetric detection healthcare environmental monitoring, food safety analysis, point-of-care testing.

BMEMat, Год журнала: 2023, Номер 1(4)

Опубликована: Сен. 8, 2023

Abstract As a multifunctional fluorescent nanomaterial, carbon dots (CDs) not only have small size, stable chemical properties, excellent photoluminescence characteristics, but also exhibit good biocompatibility and low toxicity. It has attracted considerable attention in the field of nanotechnology biological science. CDs contain abundant functional groups on surface, which retain part properties raw materials, may new photoelectric, catalytic, biomedical, other functions. In this review, we systematically summarize synthesis methods, modifications, optical main functions recent years. The application functionalized modified detection, imaging, photodynamic therapy, photothermal targeted drug delivery, gene protein biomedical fields is introduced. latest progress with its own function antioxidant, anti‐pathogen, disease treatment summarized. Finally, discuss some problems practical look forward to future development trend self‐functional combined surface modification achieve multimodal diseases.
