Hg2+ and Fe3+, as heavy metal ions that pose significant health and environmental risks, can be effectively detected using carbon dots due to their stable fluorescence properties and surface functional groups. Therefore, this work developed carbon dots derived from sugar (SCDs) using a simple hydrothermal method for sensing metal ions, antioxidant, and antimicrobial applications. SCDs with an 8.9 nm average size demonstrated excellent fluorescence properties and high photostability under UV illumination, visible light, high ionic strength, and different pH conditions. Additionally, SCDs exhibited antioxidant and antimicrobial abilities due to the surface interaction with cell membranes. A paper-based test strip application of SCDs showed effectiveness with low detection limits for metal ion detection.

Despite its prevalence, the role of lead in chronic otitis media remains largely overlooked.

The method capitalizes on the interaction between lead ions and 7,8-dihydroxy-4-phenylcoumarin, generating a distinct fluorescent product. This complex exhibit modified fluorescence characteristics compared to free 7,8-dihydroxy-4-phenylcoumarin, emitting at 505 nm when excited at 330 nm. This shift, accompanied by an increase in fluorescence intensity, enables precise lead quantification even within complex plasma matrices. Validation confirmed a consistent linear relationship within the 200–4000 ng/mL range. Application of the validated method revealed elevated lead levels in plasma samples from chronic otitis media patients compared to healthy controls. These findings suggest a potential link between lead exposure and chronic otitis media development, though further research is warranted for confirmation.

Early diagnosis and treatment of HCC can effectively reduce mortality. Carboxylesterase (CE) is abundantly present in liver tissue, which shows promise as an innovative diagnostic biomarker for HCC. Herein, we designed and synthesized a novel fluorescent probe BDPPh-CES, based on a boron dipyrromethenes (BODIPY)-styryl framework, for the ratiometric detection of CE. Upon interaction with CEs, the probe demonstrates a characteristic fluorescence emission red shift, completing the reaction within 30 min. Notably, BDPPh-CES maintains specificity against acetylcholinesterase (AChE) and various biological species, while exhibiting robust performance across physiological pH conditions. Comprehensive mechanistic investigations, combining high-resolution mass spectrometry (HRMS) analysis, density functional theory (DFT) computational studies, and molecular docking simulations, provided insights into the binding and sensing mechanisms. The high sensitivity and low cytotoxicity facilitated real-time ratiometric imaging of CEs at the cellular level, successfully distinguishing elevated CE expression in Hepa 1–6 hepatic cancer cells over AML 12 normal hepatocytes. Further validation through in vivo experiments confirmed the liver-specific accumulation and efficient CE detection capabilities.
