DUPLETS: Deformability-Assisted Dual-Particle Encapsulation Via Electrically Activated Sorting.

Current co-encapsulation methods struggle with balancing pairing rates and droplet purity. These approaches often face limitations in throughput and droplet accuracy. Prior research has shown that droplet-based systems can isolate single cells or beads effectively. However, achieving high pairing rates remains a challenge. The presence of multicell droplets reduces assay reliability. This gap motivated the development of more precise sorting methods. No prior work had resolved the pairing rate and purity dilemma simultaneously. The need for label-free and high-throughput solutions remains unmet.

The study aimed to address the limitations of co-encapsulation in droplet-based systems. It sought to improve pairing rates while minimizing multicell droplets. The goal was to enhance the purity of single-paired cell-bead droplets. The researchers focused on combining mechanical and electrical sorting. This approach was intended to increase effective throughput. The study also aimed to eliminate the need for labeling techniques. The objective was to integrate this system into existing platforms. The motivation was to improve biological assay performance and cell viability.

The DUPLETS system uses mechanical and electrical properties of droplets for sorting. It relies on deformability and electrical activation without labeling. The system screens droplets in a label-free manner. It combines mechanical and electrical characteristics for droplet differentiation. The method allows for high-throughput sorting of droplets. The system operates by analyzing individual droplet traits. It integrates into existing co-encapsulation platforms. The approach was tested for pairing rate and purity improvements.

The DUPLETS system achieved over 80% enrichment of single-paired droplets. This is eightfold higher than current co-encapsulation methods. The system reduced multicell droplets to 0.1% compared to 24% in 10× Chromium. The pairing rate and purity were significantly improved. The system operates in a label-free and high-throughput manner. It demonstrated superior performance in sorting accuracy. The system maintains high cell viability during processing. The results suggest compatibility with existing biological assays.
