Abstract: An aflatoxin nanobody immunoabsorbent and immunoaffinity column and preparation method and use thereof. The immunoabsorbent comprises a solid phase carrier and aflatoxin B1 nanobody 2014AFB-G15 coupled with the solid phase carrier. The 50% inhibiting concentration IC50 of aflatoxin B1 nanobody 2014AFB-G15 to aflatoxin B1 is 0.66 ng/mL, and the cross-reactivity of aflatoxin B1 nanobody 2014AFB-G15 to aflatoxins B2, G1, G2, and M1 are respectively 22.6%, 10.95%, 32.1% and 26%. The amino acid sequence of aflatoxin B1 nanobody 2014AFB-G15 is as depicted by SEQ ID NO: 7, and the coding gene sequence thereof is as depicted by SEQ ID NO: 8. The aflatoxin nanobody immunoaffinity column can be used for purification and concentration of sample extract prior to computer testing, and the immunoaffinity column can be reused repeatedly.

Abstract: A touch device is provided in the present disclosure. The touch device comprises a plurality of piezoelectric transducers arranged in a touch region of a substrate and a plurality of signal wires located on the substrate and electrically connecting the plurality of piezoelectric transducers. The touch device in the present disclosure can convert mechanical vibration into an electrical signal such that the signal on the touch device can be detected without using any additional driving voltage.
