Computational Molecule Design for Membrane Stress Sensors

The patent performs preliminary sensitivity estimation through computational modeling before actual synthesis and experimentation. By calculating solubility parameters and interaction energies between polymer receptors and odor molecules in silico, the system predicts which molecular structures will exhibit desired sensing performance, allowing researchers to prioritize synthesis of only the most promising candidates

The patent replaces physical trial-and-error experimentation with computational information processing. By using computer-based models to calculate solubility parameters, interaction energies, and predicted sensitivity values, the system substitutes mechanical synthesis and experimental validation with virtual screening, dramatically reducing the need for repeated physical prototyping

The patent systematically varies key molecular parameters such as solubility parameters (δ), interaction energies (ε), and polymer chain lengths in computational models to identify optimal ranges for sensor performance. By changing these parameters virtually and observing their impact on predicted sensitivity, the system identifies molecular structures that balance computational optimization with synthesis feasibility

The patent implements feedback loops where computational predictions are compared with experimental results, and the model parameters are refined accordingly. Sensitivity estimation results from computational models feed into molecular structure optimization, which then guides synthesis priorities, creating a closed-loop system that improves both prediction accuracy and synthesis feasibility over time

The patent develops a universal computational framework based on solubility parameter theory that can predict receptor-analyte interactions across diverse odor molecules. The same theoretical model and calculation methods apply whether designing for a single specific analyte or screening against hundreds of thousands of potential odor molecules, providing a scalable universal approach rather than requiring separate design methodologies for each case

The patent uses solubility parameters as key controlling variables that capture the essential physics of polymer-analyte interactions. By expressing detection sensitivity in terms of these fundamental parameters (δ, ε, molecular weight, chain length), the system reduces the complex many-body problem of designing for numerous odor molecules to optimizing a manageable set of physical parameters that can be systematically varied
