- Spectrofluorometric analysis of ASA based on fluorescence quenching of NACQDs.
- Validation of the method for linearity, sensitivity, accuracy, and precision.
Main Results
- PSP-based NACQDs were successfully synthesized and characterized.
- The developed method showed excellent linearity (r=0.996) and sensitivity (LOD=0.1 μg/mL, LOQ=0.3 μg/mL).
- High accuracy (99.36%-100.35% recovery) and precision (<0.21% RSD) were achieved for ASA quantification.
- The method was successfully applied to ASA tablet formulations.
Conclusions

Photoluminescence offers a wide range of applications due to its inherent sensitivity and selectivity. This technique allows for both direct and indirect analyses of the analyte. Direct quantitative analysis is possible when the analyte exhibits a favorable quantum yield for fluorescence or phosphorescence. However, an indirect analysis may be feasible if the analyte is not fluorescent or phosphorescent, or if the quantum yield is unfavorable. Indirect methods include reacting the analyte with...
For AAS measurements, samples must be introduced as clear solutions, often requiring extensive preliminary treatment to dissolve materials like soils, animal tissues, and minerals. Common methods for sample preparation include treatment with hot mineral acids, wet ashing, combustion in closed containers, high-temperature ashing, or fusion with reagents.
Solutions containing organic solvents, such as low-molecular-mass alcohols, esters, or ketones, enhance absorbances by increasing...
