| 摘要 |
Among other aspects, the present invention provides for the deposition of biological particles, such as cells, in a liquid, in a desired two-dimensional pattern on a planar surface of a substrate so as to permit rapid, simple, and sensitive detection of cells and/or sub-cellular components (e.g., proteins, biomarkers) disposed on the substrate. In various aspects, the systems and methods can enable reproducible high-throughput screening and/or allow for sensitive and specific detection of rare events in heterogeneous cell populations within a biological sample, with limited or no selective cell loss or sample enrichment. |
