Some embodiments of the present invention generally relate to devices and methods for determining and/or isolating cells. For example, one aspect is generally directed to methods and devices for detecting, identifying, counting, and/or potentially sorting cells of interest in blood or other biological sample. In some embodiments, blood samples (or other biological fluids) may be treated with signaling entities, such as pH-sensitive entities, that change color or otherwise produce a signal in suitable internal environments. For example, certain cells, such as cancer or fetal cells, may have differences in intracellular pH compared to other cells, which can be detected using pH-sensitive entities. In certain embodiments, the cells may be sorted based on such signaling entities; for example, illumination of cells in a suitable machine for sorting cells (e. g., using fluorescent light) may allow determination of the cells, which may also be recovered or isolated for further manipulation in some cases.
本发明的一些实施方案一般涉及用于确定和/或分离细胞的装置和方法。例如,一个方面一般涉及用于检测、识别、计数和/或可能分选血液或其他生物样本中相关细胞的方法和装置。在某些实施方案中,血液样本(或其他生物液体)可以用信号实体(如 pH 敏感实体)处理,这些实体会变色或在合适的内部环境中产生信号。例如,某些细胞(如癌细胞或胎儿细胞)与其他细胞相比,细胞内 pH 值可能存在差异,可使用 pH 值敏感实体进行检测。在某些实施方案中,可根据此类信号实体对细胞进行分选;例如,在用于分选细胞的合适机器中对细胞进行照射(如使用荧光灯),可对细胞进行测定,在某些情况下,还可对细胞进行回收或分离,以便进一步操作。
