Dmitry Bandura, Vladimir Baranov, and Scott Tanner have been awarded US Patent 7,479,630, “Method and apparatus for flow cytometry linked with elemental analysis.”

According to its abstract, the patent claims an apparatus for sequentially analyzing particles such as single cells or single beads, by spectrometry. The apparatus, an elemental flow cytometer, includes the means for sequential particle introduction; the means to vaporize, atomize, and excite or ionize the particles, or an elemental tag associated with an analyte on the particles; and the means to analyze the elemental composition of the vaporized, atomized, and excited or ionized particles, or an elemental tag associated with the particles. Methods for sequentially analyzing particles such as single cells or single beads by spectrometry are also provided.
