Carbon-doped MXene quantum dots (MNQDs) were synthesized through a hydrothermal reaction involving citric acid and ethylene diamine in the presence of MXene. Palladium nanoparticles subsequently incorporated into MNQDs integrated an iron-based metal–organic framework, forming MIL-PdMNQDs. The successful synthesis MIL-PdMNQDs was confirmed by PXRD, SEM, TEM, XPS, FTIR analyses. Modified glassy carbon screen-printed electrodes with used to measure l-ascorbic concentrations phosphate buffer solution, ranging from 10 100 nM. Cyclic voltammetry (CV) differential pulse (DPV) revealed linear anodic peak current between 52.05 82.44 μA, regression (R2) value 0.9885. In human serum diluted PBS (5 mL 95 PBS), MIL-PdMNQDs-SPE1 detected ascorbic 50 μM, illustrating DPV redox 124.39 152.54 R2 0.9901.
