摘要:
The present invention relates to a method for measuring in real time the secretion of a compound C o by a target C i , said method comprising: culturing, in a liquid medium, in a culture chamber, a plurality of targets including at least one target C i , said culture chamber comprising: (i) at least one 1st surface on which said target C i is present, the presence of said target C i generating a 1st signal; and (ii) at least one 2 nd surface that is different from said 1st surface and not coplanar with said 1st surface, which surface is functionalised by at least one ligand specifically binding to said compound C o secreted by said target C i , the specific bond between said ligand and said compound C o generating a 2nd signal that is distinct from said 1st signal; and detecting in real time said 2nd signal and optionally said 1st signal. The present invention also relates to devices possibly implemented in such a method.
