The present invention relates to a method for grafting, in a covalent manner, a coloured indicator having at least one aromatic primary amine function onto the surface of a solid substrate, including the steps that consist of: (a) preparing, from the coloured indicator having at least one aromatic primary amine function, the corresponding diazonium salt; (b) placing the solid substrate in contact with a solution containing the diazonium salt prepared in step (a) and subjecting the solution to non-electrochemical conditions for an optimal grafting time whereby organic chains in which the units are derivatives of the diazonium salt are grafted, in a covalent manner, onto the surface of the solid substrate; (c) washing the solid substrate thus grafted; (d) repeating steps (b) and (c) or possibly steps (a) to (c) at least once. The present invention also relates to a kit for implementing such a method.
本发明涉及一种以共价方式将具有至少一个芳香族
伯胺官能团的彩色指示剂接枝到固体基材表面的方法,包括以下步骤:(a) 从具有至少一个芳香族
伯胺官能团的有色指示剂中制备相应的重氮盐;(b) 将固体基质与含有在步骤(a)中制备的重氮盐的溶液接触,并将该溶液置于非电
化学条件下,以达到最佳接枝时间,从而将其中单元为重氮盐衍
生物的有机链以共价方式接枝到固体基质的表面; (c) 清洗这样接枝的固体基质; (d) 重复步骤(b)和(c),或可能重复步骤(a)至(c)至少一次。本发明还涉及一种用于实施这种方法的试剂盒。
