Abstract
An object of the present invention is to provide a biosensor and a method for immobilizing a physiologically active substance, by which preconcentration effects can be obtained at a pH that is equivalent to or higher than the isoelectric point of the physiologically active substance and the physiologically active substance can be covalently bound to the surface. The present invention provides a biosensor comprising a solid substrate to which a polymer having a primary or secondary amino group is bound, by which a physiologically active substance can be chemically immobilized following preconcentration of the substance at a pH that is equivalent to or higher than the isoelectric point of the substance.
