Method for marking a target structure, comprising the steps of: a) providing a compound V which comprises at least one dihydroxy- or trihydroxyphenyl group, b) providing a means for converting the dihydroxy- or trihydroxyphenyl group into a quinone group, c) providing a target structure, d) oxidizing the dihydroxy- or trihydroxyphenyl group of compound V to form the quinone group, and e) establishing contact between compound V and the target structure, with the result that a covalent bond can be formed, characterized in that, in step e), compound V is used in a concentration such that the maximum concentration of dihydroxy-, trihydroxyphenyl groups and quinone groups which have been introduced by compound V is ≤500 µM, preferably ≤300 µM, more preferably ≤100 µM. |
