    • PROBLEM TO BE SOLVED: To provide a system for enumeration of cells in fluids by image cytometry for assessment of target populations such as leukocyte partial group in different bodily fluids, or bacterial contamination in environmental samples, food products and bodily fluids.
      SOLUTION: Fluorescently labeled target cells are linked to magnetic particles or beads. In one embodiment, a small permanent magnet is inserted directly into the chamber containing the labeled cells. The magnets are coated with PDMS silicone rubber to provide a smooth and even surface which allows imaging on a single focal plane. The magnet is removed from the sample and illuminated with fluorescent light emitted by the target cells captured by a CCD camera. In another embodiment, a floater having a permanent magnet makes the target cells array along a single imaging plane within the sample solution. An image analysis can be performed with a novel algorithm for measuring cells on the surface reflecting the target cell concentration of the original sample.

    • 要解决的问题:提供一种用于通过图像细胞计数来计量流体中的细胞的系统,以评估靶群体,例如不同体液中的白细胞部分组,或环境样品,食品和体液中的细菌污染。 荧光标记的靶细胞与磁性颗粒或珠子连接。 在一个实施例中,将小永久磁铁直接插入含有标记细胞的腔室中。 这些磁体用PDMS硅橡胶涂覆,以提供平滑和均匀的表面,允许在单个焦平面上进行成像。 从样品中除去磁体,并用由CCD照相机俘获的靶细胞发射的荧光照射。 在另一个实施例中,具有永磁体的浮子使得靶单元沿着样品溶液内的单个成像平面排列。 可以使用用于测量反映原始样品的靶细胞浓度的表面上的细胞的新颖算法进行图像分析。 版权所有(C)2009,JPO&INPIT
