Abstract: Disclosed in the present invention are a digital nucleic acid amplification testing method and an integrated detection system based on CRISPR-Cas technology. The integrated detection system comprises an integrated reaction chip, a temperature control module, a light source and an optical signal detector. The method comprises: uniformly dividing a nucleic acid amplification reagent into amplification micro-droplets, then mixing the amplification micro-droplets after digital nucleic acid amplification with detection micro-droplets containing CRISPR-Cas detection reagent to perform a CRISPR reaction, and when the reaction is finished, detecting an optical signal to realize high-specificity testing of a target object, and the concentration or copy number of nucleic acid molecules in a sample to be tested is also obtained, and high-sensitivity absolute quantitative testing of a target object is realized.

Abstract: An embedded searching system uses an application name to search for the interface specifications for the application. The interface specifications are used to update default registry information of the operating system. Different applications can thus be embedded with a search field. This increases the convenience of searching for the applications. The mechanism also produces a corresponding method.
