Mathematical Modelling of Biosensors

Mathematical modeling of biosensors is the process of describing and forecasting biosensor behavior, such as sensitivity, specificity, and response time, using mathematical equations. These models can be applied to experimental data interpretation as well as biosensor design and performance optimization.

One common approach to mathematical modeling of biosensors is based on the Langmuir isotherm, which describes the binding of a ligand to a receptor as a reversible equilibrium process. This model assumes that the biosensor response is proportional to the amount of ligand bound to the receptor, and that the binding is independent of the concentration of other species in the sample.

The application of thermodynamic and kinetic models plays a vital role in the mathematical simulation of biosensors. These models depict alterations in free energy resulting from interactions between ligands and receptors, as well as the rates at which ligands attach to and detach from receptors.

Mathematical simulations can also be employed to understand the behavior of biosensors in diverse experimental conditions, including variations in temperature, pH, or ionic strength. Such simulations are valuable in pinpointing potential sources of interference or cross-reactivity, as well as enhancing the overall performance of biosensors in different operational scenarios.

Furthermore, mathematical modeling serves as a valuable tool for extracting pertinent information about the analyzed sample and interpreting experimental data. For instance, it is possible to fit experimental data to a mathematical model, further aiding in optimizing biosensor performance.
