  • Publication number: 20060133959
    Abstract: A luminometer includes a movable carrier carrying a number of luminescence collectors arranged in an array for simultaneously detecting the same number of samples received in multiple wells defined in a microplate. An optic fiber optically couples each luminescence detector to an associated charge-coupled device whereby a luminescence signal emitted from each sample is transmitted to the charge-coupled device and converted thereby into a corresponding electric signal. The charge-coupled devices are isolated from each other by partitions, which eliminate undesired interference among the luminescence signals transmitted to the charge-coupled device. A driving unit is provided to move the carrier between rows of the wells defined in the microplate.

    Abstract: A biochip scanner device includes a light source for emitting a light beam; a light processing unit for focusing the light beam onto the biochip to excite fluorescence from a sample spot on the biochip; a filter for filtering off the light beam from the light source and the scattered light from the surface on the biochip; a photomultiplier tube (PMT) for detecting and converting the fluorescence into a current signal; and an output device for outputting/displaying the current signal detected by the PMT. The output device controls the platform to match the pattern of the biochip. No conversion of the output signal of the output device into image data is needed. A real-time analysis proceeds while samples are being scanned on the biochip.
