As a result, both the detection limit of the sensor decreased by 2～3 magnitudes and the signal magnitude increased about ten times than that of fly labellar single hairs. The sensitivity to many stimulants from simple molecules such as NaCl, KCl, sucrose, glycine, proline, glutamic acid and aspatic acid to macromolecule such as bovine surem albumin was lower than 10〓mol L〓. For this reason, the maxillary palp of cockroach is reveled as an important candidate for construction of a new type of intact-receptor biosensors.
