2results about How to "Realize instant detection" patented technology

The application discloses a kind of plate thickness and wedge-shaped edge detection device, with conveying assembly, cleaning assembly, laser detector and warning assembly;Conveying assembly is used to convey gypsum board, and the both sides of conveying assembly are provided with notch;Cleaning assembly is set to the upstream of conveying assembly, for removing water stain dust on the surface of gypsum board;Laser detector is symmetrically set to the both sides of conveying assembly, and the upper end and middle part of laser detector are respectively provided with two laser sensors and controller, and laser sensor is electrically connected to controller;Laser detector side is also provided with warning assembly, and controller can control warning assembly to send alarm when receiving abnormal signal.The application exposes the edge of gypsum board by setting notch on the side of conveying assembly, and sets laser detector at the notch, so that two laser sensors can detect the distance from the upper and lower surfaces of gypsum board when gypsum board passes through laser detector, so as to obtain the edge and thickness of gypsum board, and realize the instant detection of the edge thickness of gypsum board.

This invention relates to the field of biodetection technology, providing an enzyme cascade reaction system for the detection of nucleic acids and protein molecules, comprising BER endonuclease and Argonaute endonuclease; wherein the BER endonuclease is one or more selected from APE1, FEN1, Fpg, UDG, and T7endonuclease, and the Argonaute endonuclease is one or more selected from pfAgo, CpAgo, CbAgo, TtAgo, RasAgo, MjAgo, and NgAgo. This invention also provides a method for detecting nucleic acids and protein molecules using the above system, and the application of the above system in the preparation of target nucleic acid and target protein molecule products from detection samples. This invention utilizes the synergistic enzyme activity of APE1 and PfAgo in the enzyme cascade reaction system to achieve real-time detection of nucleic acid and protein biomarkers without pre-amplification within 45 minutes.
