Outline of Final Research Achievements |
In this study, we investigated the ion sensitivity found in the GaInAsP semiconductor photonic crystal nanolaser and realized a novel biosensor based on this phenomenon. First, the mechanism of the nanolaser in response to ions in aqueous solution was clarified, and its external control using an electrochemical circuit was demonstrated. Nanolasers were then applied to detect four different biomarker proteins, including Alzheimer's disease. We succeeded in ultrasensitive and selective detection from concentrations well below the detection limits of conventional methods and/or simpler procedure screening, which represents great potential for medical diagnosis.
