Abstract: A data sharing method includes an electronic device that sends data such as a picture, a document, a link, and a chat record to a server contact in an instant messaging application, shares the data to a device bound with a user, such as a printer, a projector, or a display, and triggers the device to perform an operation such as printing, projection, or mirroring such that a process of printing data, projection, mirroring, and the like using the electronic device can be intuitive, simple, and effective for the user.

Abstract: An application of thiolated single-stranded DNA enhances specific amplification of polymerase chain reaction, namely a method for enhancing specific amplification of polymerase chain reaction by utilizing thiolated single-stranded DNA, which includes the following step: adding an appropriate amount of the thiolated single-stranded DNA into a PCR system to perform PCR amplification, wherein the appropriate amount means that the final concentration of the thiolated single-stranded DNA in a 20 ?L reaction system is not less than 15 ?M. The thiolated single-stranded DNA meets the following conditions: the thiolated single-stranded DNA is one segment of any sequence which is non-complementary and non-homologous to a target sequence; the Tm value is not less than 37.7° C.; and at least one end contains a thiolalkyl group SH—C6H12—.
