  • Patent number: 7767444
    Abstract: An apparatus and method for analyzing biological cells and other particles using an external laser cavity. Microfluidic channels contain and transport biological cells to be analyzed. A laser diode provides light for cell analysis. An external cavity is provided between one surface of the laser diode and a mirror opposite thereto. A microlens set focuses the light on only one cell as it passes through the external cavity. The presence of the cell in the external cavity gives a weak feedback toward the laser diode. The emission frequency and the output power of the laser are both functions of the length of the external cavity. Therefore, the variation of cavity length can be deduced from these parameters, where the variation is caused by changing the refractive index or size of the cell in the cavity.

  • Publication number: 20080213821
    Abstract: A microfluidic system for separating, purifying and counting cell sub-populations, utilising steering of liquid flows in microfluidic channels in a cell focusing region (first dotted circle area); having the integration of the optical detection mechanism and a microchannel structure made from moulding. A master is photolithographically patterned on a soft PDMS silicon or polymer material. After being moulded and peeled off the master, the micro-channel structure is sealed on a hard substrate with openings punched through for wells (14, 12, 36, 38, 40). An optical detection region (20) discriminates different types of cells that have been formed into a single flow (30). Electromagnetic fields are used to steer (32) the flows of cells according to the signals from the optical detection region into branch channels leading to the punched wells for separate collection. The system can have parallel systems that increase throughput or cascade systems to provide several analysis steps.
