Although the intact-receptor based biosensors of the maxillary palp of cockroach Periplaneta Americana are not yet practical analytical devices at present. Yet, sensitive and selective responses to biomolecules involving amino acids and protein, as well as some simple substance such as salts and sugars have been firstly obtained. It is already evident that receptor based biosensors are enormously superior to isolated receptor biosensors in terms of response time and recovery times, thus, the intact receptor biosensor worth of further investigation and development.
