    摘要: Disclosed are a phenylboronic acid monomer and a phenylboronic acid polymer, each of which can have a pKa value suitable for the use under physiological environments and can be used for various applications. The pheanylboronic acid monomer has a structure represented by formula (13) and therefore has high hydrophilicity, can have a satisfactorily low pKa value when the phenyl ring is fluorinated, and can have a polymerizable unsaturated bond. The phenylboronic acid monomer has high hydrophilicity at a pKa value of 7.4 or less which is a physiological level, and can be polymerized with a wide variety of monomers to produce polymers suitable for the intended purposes.

    摘要: Since conventional DNA sequence analyzing technologies are based on the fundamental principle of fluorescent detection, expensive, complex optical systems and laser sources have been necessary.A field-effect device for gene detection of the present invention analyzes a base sequence by immobilizing a single-strand nucleic acid probe at a gate portion, inducing hybridization at the gate portion to form a double-stranded DNA, inducing elongation reaction by adding a DNA polymerase and one of the substrates, and measuring the electrical characteristic of the field-effect device caused by elongation reaction.Since the elongation reaction of one base induced at the gate portion can be directly converted to an electrical signal, expensive lasers or complex optical systems are not needed. Thus, a small gene polymorphism detection system that can conduct measurement at high precision can be provided.
