강연주제: Organic Photonics for Effective Bio/Chemical Sensors

Organic semiconductors are attractive photonic and electronic materials due to their high luminescence, quantum efficiency, color tunability, and size-dependent optoelectronic properties. π-conjugated organic semiconducctors have become qualified candidates for biosensing owing to their unique optoelectronic properties and excellent biocompatibility. p-conjugated polymer-based bio/chemical sensors show enhanced detection capability because a local single change can affect the properties of the whole system. Bio/chemical materials can be readily identified through the variation of light-emitting characteristics of functional organic structures when appropriate receptors are linked to their active surfaces. For instance, the luminescence intensity and color of the light-emitting polymers can be changed upon specific biological interactions. In this talk, we introduce experimentally the response to bio/chemical events by luminescent organic semiconductors with success in our laboratory.
