Controlled Hydrogel Microparticles for Predictable Acoustophoresis

The patent applies parameter changes by systematically varying physical and chemical parameters of the synthetic particles during manufacturing. This includes controlling particle size, density, compressibility, elastic modulus, and porosity through adjusted synthesis conditions. By establishing controlled parameter ranges, the patent ensures predictable and reliable separation performance in fluid-based processes.

The patent employs composite materials to create synthetic particles with tailored characteristics. By combining different materials with specific properties, the patent achieves controlled particle characteristics that balance separation performance with predictable behavior. The composite structure allows independent optimization of various particle properties.

The patent applies preliminary action by incorporating binding capabilities into the synthetic particle structure during the manufacturing process rather than adding them afterward. Surface treatments such as antibody conjugation are performed as integral parts of the particle synthesis, establishing binding specificity before the particles are deployed in separation applications. This reduces subsequent manufacturing complexity.

The patent uses intermediary substances or molecules that facilitate the binding between synthetic particles and target particles. These intermediaries, such as antibodies or ligands, are integrated into the particle surface during manufacturing, creating a controlled binding interface that enhances specificity without requiring complex post-processing steps.

The patent applies parameter changes by adjusting the physical properties of synthetic particles to achieve desired acoustic contrast. This includes modifying density, compressibility, and other acoustic properties through controlled synthesis. By establishing specific parameter ranges, the patent optimizes separation efficiency in acoustophoresis devices while maintaining manageable design complexity.

The patent employs local quality by tailoring specific regions or aspects of the particle structure to achieve the desired acoustic contrast. Rather than uniformly modifying the entire particle, the patent applies localized property changes in specific regions, allowing optimization of acoustic characteristics without unnecessarily complicating the overall particle design.
