Nanomaterials have become essential components for the development of biosensors since such nanosized compds. were shown to clearly increase the anal. performance. The improvements are mainly related to an increased surface area, thus providing an enhanced accessibility for the analyte, the compd. to be detected, to the receptor unit, the sensing element. Nanomaterials can also add value to biosensor devices due to their intrinsic phys. or chem. properties and can even act as transducers for the signal capture. Among the vast amt. of examples where nanomaterials demonstrate their superiority to bulk materials, the combination of different nano-objects with different characteristics can create phenomena which contribute to new or improved signal capture setups. These phenomena and their utility in biosensor devices are summarized in a non-exhaustive way where the principles behind these synergetic effects are emphasized. [on SciFinder(R)]
