Abstract
= 0.996), corresponding to a detection limit of 0.02 µM. This broad and well-defined linear range confirms the strong quantitative capability of the simulated sensor design. These findings establish a mechanistic foundation for the rational design of β-cyclodextrin-functionalized carbon electrodes and provide a broadly applicable strategy for next-generation electrochemical sensors targeting hydrophobic nitroaromatic pharmaceuticals and related bioactive species.
