Abstract:
The invention features devices and methods for the deterministic separation of particles. Exemplary methods include the enrichment of a sample in a desired particle or the alteration of a desired particle in the device. The devices and methods are advantageously employed to enrich for rare cells, e. g. , fetal cells, present in a sample, e. g. , maternal blood and rare cell components, e. g. , fetal cell nuclei. The invention further provides a method for preferentially lysing cells of interest in a sample, e. g. , to extract clinical information from a cellular component, e. g. , a nucleus, of the cells of interest. In general, the method employs differential lysis between the cells of interest and other cells (e. g. , other nucleated cells) in the sample.
