A biosensor chip includes a substrate, a polymer having an anionic functional group and being arranged on a surface of the substrate, a polyamino group which is directly or indirectly bound to the anionic functional group at a surface of the polymer, and a long-chain alkyl-based group which is directly or indirectly bound to the anionic functional group at the surface of the polymer. Therefore, the biosensor chip can immobilize a bioactive material on the surface of the biosensor chip without influence of electric charge repulsion.
一种生物传感器芯片包括基底、具有阴离子官能团并排列在基底表面的聚合物、在聚合物表面与阴离子官能团直接或间接结合的聚氨基,以及在聚合物表面与阴离子官能团直接或间接结合的长链烷基。因此,生物传感器芯片可以在不受电荷排斥影响的情况下,在生物传感器芯片表面固定生物活性材料。
