Abstract: A valve system for driving fluid and a method for using the same are provided. The valve system includes a fluid unit far away from the rotation center, a fluid unit close to the rotation center, a fluid transferring unit and a gas path pipeline for communicating the fluid unit close to the rotation center with the fluid unit far away from the rotation center. A rotation radius of a fluid outlet of the fluid unit far away from the rotation center is greater than that of a fluid inlet of the fluid unit close to the rotation center. The fluid outlet of the fluid unit far away from the rotation center is located at an end thereof away from the rotation center, and the fluid inlet of the fluid unit close to the rotation center is located at an end thereof close to the rotation center.

Abstract: A nucleic acid extraction composition, reagents and kits containing the same and uses thereof. Provided is a nucleic acid extraction and purification reagent free of volatile organic solvents, which prevents the damage of volatile organic solvents to people and greatly improves the timeliness of nucleic acid extraction and purification, making the operation extremely simple, and the nucleic acid can be obtained within 10 minutes. The obtained nucleic acid may be used for biological reactions such as PCR, NASBA, LAMP and RPA. Moreover, the reagents of the present disclosure may be used to extract nucleic acids of cells, bacteria, fungi, DNA viruses and RNA viruses from various samples such as blood, throat swab preserving fluid, saliva, urine, sputum, excrement and the like, and very suitable for clinical and scientific research uses.

Abstract: A multi-index detection microfluidic chip is provided. A bottom plate (1) and a cover plate (2) that matches the bottom plate (1) and seals it are provided in the microfluidic chip. The center of the microfluidic chip has a through-hole (3). The bottom plate (1) has one or more wave-shaped main channel(s) (4), one end of each of the main channel (4) connected to a sample injection hole (9) on the bottom plate (1), and the other end connected to an exhaust hole (10) on the bottom plate (1). The valley on the main channel (1) is distal to the through-hole (3), and the peak is proximal to the through-hole (3). Each valley of the main channel (1) is connected to a reaction chamber (6) by a linking channel (5). The linking channel (5) comprises one or more buffering chambers (7). The microfluidic chip can be used in detection by fluorescence, turbidity, color, detection equipment, and/or direct observation by the naked eyes. The detection is real-time as the reaction occurs or after the reaction.

Abstract: In one aspect, disclosed herein are methods for packaging biochips, including microfluidic chips. The method can comprise bonding a substrate and a cover slide, packaging the bonded chip, creating a vacuum in the package, and applying a pressure on the packaged chip. The method is particularly useful for minimizing bubble formation during low-cost and mass production of microfluidic chips.

Abstract: A BIOS (Basic Input/Output System) setting method is disclosed, which is applicable to a computer equipped with a MEMORY a CMOS RAM (Complementary Metal Oxide Semiconductor Random Access Memory), and a BIOS-ROM (Basic Input/Output System Read-Only Memory) storing a first setting document. The BIOS setting method includes: providing a setting interface to allow a user to perform settings so as to form a second setting document; storing the second setting document in the BIOS-ROM; and loading the first and second setting documents to the MEMORY during a POST (Power On Self Test) process of the computer; saving the first setting document, or alternatively revising the first setting document and/or combining the first setting document with the second setting document according to the second setting document if loaded, so as to form a third setting document; and loading the third setting document to the CMOS RAM to perform a system initialization according to the third setting document.

Abstract: The invention provides a Basic Input/Output System (BIOS), a computer device and a method for recovering the BIOS. The BIOS includes a first boot block, a second boot block and a main BIOS block. The computer device includes a control chip disposed therein and said BIOS. When the programs in the first boot block and the main BIOS block are damaged, the second boot block can be selected so as for the BIOS to boot from the second boot block. Meanwhile, a recovery module of the second boot block can be utilized to recover the first boot block and/or the main BIOS block.

Abstract: The invention provides a method for installing an operating system in a computer having a plurality of hard disks. The method includes: establishing a BBS table in a fixed address space of a memory for recording a default boot sequence of the hard disks via a BIOS memory; setting the default boot sequence of the hard disks so as to form an actual boot sequence; and interchanging, in boot sequential order, a hard disk among the hard disks which have the highest boot priority in the default boot sequence and that of a hard disk having the highest boot priority in the actual boot sequence, such that the operating system is installed in the hard disk having the highest boot priority in the actual boot sequence, thereby improving the booting efficiency of the computer.
