Disclosed is an image probing conjugate. The conjugate comprises a nanoparticle and a targeting agent. The nanoparticle comprises a dye which is encapsulated by a functionalized polymer, and the targeting agent is bound to the functional group of the polymer. The nanoparticle provides the conjugate with improved stability and an increased concentration of the dye. Therefore, the conjugate of the invention can be used for probing a small target which otherwise cannot be detected. Bonding the targeting agent to the nanoparticle allows precise image probing from the location where the targeting agent is placed.
