The filed patent (Publication Number: US20230407372A1) describes a method that involves capturing target nucleic acid material from a biological sample across an array of wells on a substrate. The method aims to achieve a specific capture state for each well in the array, ensuring that each well contains a specific target from a set of targets without any contamination. A sequence of reagents, including water, is delivered to process the target nucleic acid material in each well. To prevent leakage and cross-contamination between wells, at least one of the reagents is displaced with a liquid immiscible with water, effectively partitioning each well and maintaining the integrity of the samples.

This innovative method offers a solution to the challenge of processing target nucleic acid material in a high-throughput manner while minimizing the risk of contamination between samples. By utilizing a liquid immiscible with water to partition the wells, the method ensures that each well remains isolated from adjacent wells, reducing the potential for leakage and maintaining the integrity of the samples throughout the processing steps. This approach not only improves the efficiency of processing biological samples but also enhances the reliability and accuracy of the results obtained. Overall, the patent presents a novel and practical technique for handling target nucleic acid material in a controlled and precise manner, with potential applications in various fields such as research, diagnostics, and personalized medicine.
