The present invention relates to labels capable of forming a covalent or non-covalent bond with a target molecule, consisting of a dye to which there is bonded in a covalent manner by one or more carbons of its chemical structure:
one or more [FUNC] group(s), and
optionally one or more [SOL] group(s),
said label having the general formula:
[DYE] representing the dye;
[FUNC] each independently representing an -X-A-Z group, in which:
X is chosen from the group consisting of an oxygen atom, a sulphur atom, an NR

alkyl group;
A is chosen from the group consisting of an alkylene group or an alkylene-arylene group;
Z is a reactive chemical function;

A′ is chosen from the group consisting of an alkylene group or an alkylene-arylene group;
Z′ is a polar or apolar group.
