1Productivity
If conventional methods are used to determine molecular interaction properties, then the analysis can be performed, but the determination is not fast or reliable enough
Solution Approach 1:
The patent applies parameter changes by subjecting the sample to a condition jump (change in temperature, pressure, or other physical conditions) to perturb the molecular interactions from equilibrium. This allows the system to relax back to equilibrium and provides measurable signals about interaction characteristics. By changing physical parameters and monitoring the relaxation process, the method achieves both fast and reliable determination of molecular interaction properties.
Solution Approach 2:
The patent replaces conventional mechanical or chemical analysis methods with a physical condition jump approach combined with signal detection. Instead of using complex mechanical separation or chemical reactions to study molecular interactions, the method uses physical condition changes (temperature, pressure) and monitors the resulting signal changes, providing a faster and more reliable measurement approach.
2Measurement precision
If a condition jump is applied to bring the particle in a non-equilibrium state, then the relaxation process can be measured, but the sample may be degraded
Solution Approach 1:
The patent employs periodic or controlled condition jumps followed by relaxation periods. By applying the condition jump in a controlled manner and allowing the system to relax, the method obtains precise measurement data while minimizing cumulative damage to the sample. The periodic nature of the measurement cycles allows for repeated analyses without progressive degradation.
Solution Approach 2:
The patent uses a marker or probe as an intermediary to indirectly measure the molecular interaction properties. Instead of directly observing the molecular interactions which may be sensitive to degradation, the marker provides a measurable signal that reflects the interaction state, allowing measurement without direct manipulation of the sensitive molecular components.
3Reliability
If the marker signal is read out over time during relaxation, then accurate molecular interaction properties can be determined, but the measurement time increases
Solution Approach 1:
The patent performs preliminary actions by pre-equilibrating the sample before the condition jump and preparing the detection system in advance. This allows the relaxation process to be measured more efficiently from the point of perturbation, reducing the total measurement time while maintaining accuracy. The preliminary preparation ensures that the relaxation signal is clear and measurable from the start.
Solution Approach 2:
The patent maintains continuous monitoring of the marker signal throughout the relaxation process, ensuring that the measurement captures the complete relaxation trajectory. By continuously reading the signal without interruption and analyzing the entire relaxation curve, the method achieves accurate molecular interaction properties without requiring additional time for repeated measurements.
