摘要：
Diffusion kinetics over fractal geometries are governed by anomalous subdiffusion processes for non-energetically driven adsorption/desorption of analyte over the sensor surface. This paper proposes a more accurate model to analytically interpret and predict the sensor kinetics in microscopic domain and uses Langmuir adsorption isotherm to model its response.
