Self-driven enrichment and purification with porous super-absorbent polymer beads
Innovative porous super-absorbent polymer beads for efficient enrichment and purification of biological samples, enabling rapid target isolation and analysis.
Overview
The self-driven enrichment and purification system utilizes porous super-absorbent polymer beads (PSAPBs) to enhance the precision and efficiency of biological sample preparation. These beads are engineered to separate and purify target analytes from complex mixtures. The system includes low-porosity PSAPBs (LP-PSAPBs), which rapidly absorb water and act as an enrichment matrix, and high-porosity PSAPBs (HP-PSAPBs) with adjustable pore sizes to selectively capture target molecules, ranging from nanometer to micron dimensions. This innovative method simplifies downstream analysis by providing a concentrated and purified solution.
Technical specifications
- LP-PSAPBs: Function as concentrators, absorbing water swiftly and excluding pathogens.
- HP-PSAPBs: Feature tunable pores for targeted purification, efficiently capturing and isolating analytes.
- Release Mechanism: Encapsulated analytes are released through brief sonication, ensuring rapid and effective sample preparation.
- Application Versatility: Demonstrated efficacy in media like saline, blood, plasma, and urine.
Technology readiness level
Currently at TRL 5, this technology has been validated in laboratory settings with successful demonstrations of RNA and virus release. Ongoing developments aim to optimize pore size for broader target range and validate performance in complex sample matrices.
