Abstract

Herein, we have developed a novel aggregation-induced emission (AIE) probe and three-dimensional (3D) printed portable device for copper (Cu) sensing in an aqueous medium. A ubiquitous synthetic route has been employed to devise the anthracene-conjugated imidazo[1,5-a]pyridine (TL19) probe as a unique anchor for Cu ions. The TL19 is meticulously characterized through pivotal spectroscopic techniques, and the satisfactory results were obtained. The solvatochromic analysis and density functional theory calculations cohesively reveal that the TL19 exhibits the intramolecular charge transfer transition upon photoexcitation. Intriguingly, the TL19 exhibits spherically shaped nanoaggregates and enhanced fluorescence in DMSO/water (10:90) mixtures. This fluorescent nanoaggregate instantaneously responded toward the detection of Cu via a deaggregation mechanism. The detection limit is found to be 9 pM in an aqueous medium. Further, the detection of Cu in the HeLa cells has also been achieved due to bright green fluorescence, photostability, and biocompatibility nature of TL19 aggregates. On the other hand, an internet of things (IoT)-embedded 3D printed portable device is constructed for the detection of Cu ions in real water samples. The Cu detection is achieved through an IoT device, and results were acknowledged through an android application in 3.32 s round-trip time. Thus, the IoT-enabled AIE probe could be a prospective device for Cu detection in a constrained environment.

摘要

在此,我们开发了一种新型的聚集诱导发光(AIE)探针和三维(3D)打印便携式设备,用于在水性介质中检测铜(Cu)。我们采用了一种普遍的合成路线来设计蒽共轭咪唑并[1,5-a]吡啶(TL19)探针,作为铜离子的独特锚定物。通过关键的光谱技术对TL19进行了细致的表征,并获得了令人满意的结果。溶剂化显色分析和密度泛函理论计算共同表明,TL19在光激发时表现出分子内电荷转移跃迁。有趣的是,TL19在二甲基亚砜/水(10:90)混合物中呈现球形纳米聚集体并增强了荧光。这种荧光纳米聚集体通过解聚机制对铜的检测立即做出响应。发现在水性介质中的检测限为9皮摩尔。此外,由于TL19聚集体的亮绿色荧光、光稳定性和生物相容性,还实现了对HeLa细胞中铜的检测。另一方面,构建了一种嵌入物联网(IoT)的3D打印便携式设备,用于检测实际水样中的铜离子。通过物联网设备实现了铜的检测,并通过安卓应用程序在3.32秒的往返时间内得到了结果确认。因此,这种基于物联网的AIE探针可能是在受限环境中检测铜的一种有前景的设备。
