| Research Abstract |
We developed high-sensitivity bio-sensor based on photonic crystal nanolasers with a nano-slot structure. In a test experiment against BSA protein with a low attachment force, a very low detection limit of 255 fM was achieved, suggesting an excellent sensitivity. In a more practical experiment against SA protein, an ultralow concentration of 60 zM was detected without contaminants and<1 aM even with 1 trillion higher concentration BSA as contaminants. These results satisfy the requirements from medical diagnoses for detecting low-concentration bio-markers in human blood.
