  • Publication number: 20230174578
    Abstract: The present invention relates to the field of biochips, and provides a chip surface linker and a preparation method and a use therefor. The chip surface linker is obtained by means of applying a direct current voltage to an aromatic amine bonding molecule in the presence of an acid and a nitrite to cause a reaction with a chip surface to form a bonding molecular group connected the chip surface, and then using a functional molecular for reaction and modification to add a functional molecular group containing a hydroxyl group and an ester group. The chip surface linker obtained in the present invention is able to bond more stably with a chip surface, being stable in hot water and basic conditions, and features relatively good electrical conductivity, stability during energization, and resistance to organic solvents required for nucleic acid synthesis, and is thus very advantageous for subsequent nucleic acid synthesis and other uses.

  • Patent number: 11061882
    Abstract: The present disclosure relates to a system, method and non-transitory computer readable medium. The system includes at least one computer-readable storage medium including a set of instructions and at least one processor in communication with the at least one computer-readable storage medium. When executing the set of instructions, the at least one processor is directed to: obtain a plurality of sub-tables, each being associated with one or more fields of a target wide table; generate a plurality of intermediate tables, each being directly or indirectly based on one or more of the plurality of sub-tables, wherein at least two of the plurality of intermediate tables are generated in parallel; and determine the target wide table based on the plurality of intermediate tables.
