Abstract Hexavalent chromium (Cr 6+ ) ions in drinking water pose a significant risk to human health, being leading cause for neurological disorders, organ damage, and infertility. This study introduces an ultrasensitive method detecting trace Cr over wide concentration range (≈ 100 pM – µM) through fluorescence enhancement signatures via integration of both covalent non‐covalent interaction strategies on carbon quantum dots (CQD). The functionalization is achieved from dual‐functionalized CQD (CQD‐(NH 2 , COOH)) derived coffee‐waste. Additionally, the approach integrates CQD‐(NH COOH) with graphitic nitride (g‐C 3 N 4 form 2D/2D heterostructure. synergy between g‐C mid‐gap band their structure, allowing multiple carrier excitation recombination states, significantly enhancing quenching signal. combination allows achieve detection sensitivity down ≈100 concentration—matching World Health Organization's 96 permissible limit total water. Furthermore, 70 reported mixture twelve ions, including cations anions, surpassing current state‐of‐the‐art limits. These results highlight potential dual modification strategy nanomaterials set new standards wide‐range fluorescent sensing applications.

Organelle Targeting Self-Assembled Fluorescent Probe for Anticancer Treatment

Chemosensors, Год журнала: 2024, Номер 12(7), С. 138 - 138

Опубликована: Июль 11, 2024

Organic fluorescent probes have attracted attention for bioimaging due to their advantages, including high sensitivity, biocompatibility, and multi-functionality. However, some limitations related low signal-to-background ratio false positive negative signals make them difficult in situ target detection. Recently, organelle targeting self-assembled been studied meet this demand. Most of the dye molecules suffer from a quenching effect, but, specifically, dyes like Pyrene, Near-Infrared (NIR), Nitrobenzoxadiazole (NBD), Fluorescein isothiocyanate (FITC), Naphthalenediimides (NDI), Aggregation induced emission (AIE) show unique characteristics when they undergo self-assembly or aggregation. Therefore, review, we classified according type provided an overview organelle-targeting strategy with emphasis on construction nanostructures within complex cellular environments. Results demonstrated that effectively localized inside organelles (mitochondria, lysosome, golgi body) form various possess bio-functionality long retention time, membrane disruption/ROS generation/enzyme activity suppression ability, enhanced photodynamic properties anticancer treatment. Furthermore, systematically discussed challenges remain be resolved performance these mentioned future directions design molecules.
