| Outline of Final Research Achievements |
We here established a multi-analyte detection method using an organic TFT (OTFT) sensor functionalized with “an artificial receptor”. The artificial receptor exhibited a cross reactivity, the fingerprint-like response pattern of which was obtained based on a combination of the sensor and target analytes under various pH conditions. In conventional pattern-recognition based chemical sensing systems, various types of sensors have been required to obtain a multi-response pattern. In fact, however, only few sensors played significant roles in discrimination of multi-analytes. Thus, an approach to decrease the number of sensors is highly demanded for fabrication of an efficient array system. In this research, we showed a strategy to achieve multi-recognition using a small number of sensors. We believe that our strategy can open up a new avenue for information rich response patterns even in a small number of the OTFT sensors.
