Abstract

The invention relates to a sensor molecule for detecting a target molecule comprising: (a) a rod-like molecule L and a rod-like molecule R connected to each other by a joint molecule C to form a hinge; (b) a target binding molecule A bonded to the end of rod-like molecule L opposite to the joint molecule C; (c) a binding molecule A′ bonded to the end of rod-like molecule R opposite the joint molecule C; wherein the target binding molecule A is arranged to bind to the target molecule to be detected, and binding molecule A′ is arranged to bind to: i) the same target molecule as target binding molecule A; or ii) a complex of the target binding molecule A and the target; and wherein the hinge is biased into an open position, such that target binding molecule A and binding molecule A′ are biased apart by the hinge.
