Abstract

A ratiometric nanosensor was developed for detecting methyl orange (MO) based on down/up-conversion luminescence achieved by a triplet–triplet annihilation upconversion luminescence (TTA-UCL) system. The probe, utilizing sensitizer and annihilator fluorophores encapsulated in nanomicelles, demonstrated high sensitivity and selectivity for MO detection. The energy transfer from UCL to MO endowed the sensor with responsive capabilities. The unaffected triplet–triplet energy transfer process maintained the phosphorescence signal constant, serving as a reference to construct the ratiometric sensor along with the UCL signal. Additionally, a smartphone-assisted colorimetric detection method was also developed based on the ratiometric sensor, enabling rapid and convenient detection of MO without the need for a spectrometer. The performance of the nanosensor in real water samples confirmed its potential for practical environmental applications.

基于下/上转换发光技术的比率纳米传感器在智能手机辅助下检测水中的痕量甲基橙

基于三重-三重湮灭上转换发光（TTA-UCL）系统实现的下/上转换发光，开发了一种用于检测甲基橙（MO）的比率计纳米传感器。该探针利用封装在纳米微孔中的敏化剂和湮灭荧光团，在 MO 检测方面具有高灵敏度和高选择性。从 UCL 到 MO 的能量转移赋予了传感器响应能力。不受影响的三重-三重能量转移过程使磷光信号保持恒定，与 UCL 信号一起作为构建比率传感器的参考。此外，基于该比率传感器还开发了一种智能手机辅助比色检测方法，无需光谱仪即可快速方便地检测 MO。纳米传感器在实际水样中的表现证实了其在实际环境应用中的潜力。

期刊介绍： Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (SAA) is an interdisciplinary journal which spans from basic to applied aspects of optical spectroscopy in chemistry, medicine, biology, and materials science. The journal publishes original scientific papers that feature high-quality spectroscopic data and analysis. From the broad range of optical spectroscopies, the emphasis is on electronic, vibrational or rotational spectra of molecules, rather than on spectroscopy based on magnetic moments. Criteria for publication in SAA are novelty, uniqueness, and outstanding quality. Routine applications of spectroscopic techniques and computational methods are not appropriate. Topics of particular interest of Spectrochimica Acta Part A include, but are not limited to: Spectroscopy and dynamics of bioanalytical, biomedical, environmental, and atmospheric sciences, Novel experimental techniques or instrumentation for molecular spectroscopy, Novel theoretical and computational methods, Novel applications in photochemistry and photobiology, Novel interpretational approaches as well as advances in data analysis based on electronic or vibrational spectroscopy.
