  • Patent number: 11796474
    Abstract: The present invention relates to a test sample receiving block and a microbial detection apparatus using the same. The test sample receiving block may include a sample receiving block having a sample groove portion formed therein, the sample groove portion containing the sample so that a light emission module emits light to the sample and a sensor module can detect a speckle generated when the emitted light is scattered by motion of bacteria or microbes contained in the sample, wherein the sample receiving block is surface-treated to increase an optical path of light reaching the sensor module when the emitted light is reflected or scattered by the sample accommodated in the sample groove portion, so that a pattern is formed on a surface of the sample groove portion.
