Patent ID: 8785136

Claim:
An immunodetection probe, comprising: a needle structure configured to be inserted into an organic tissue, wherein the needle structure comprises a compartment; a dialysis membrane configured to isolate the compartment from the organic tissue; a detection device comprising a detection portion and a plurality of receptors, wherein the plurality of receptors are disposed on an end surface of the detection portion for conjugating target antibodies, and the detection portion is disposed in the compartment; a first optical fiber coupled to the needle structure and configured to introduce light incident on photo-induced molecules adjacent to the end surface of the detection portion so as to cause a change in the pH level of solution adjacent to the end surface of the detection portion; and a pair of tubes connected to the compartment, wherein one of the pair of tubes is configured to transport solution containing the photo-induced molecules into the compartment and another of the pair of the tubes is configured to transport the solution containing the photo-induced molecules out of the compartment.
