| Research Abstract |
In order to improve and stabilize the precision and performance of liposome biosensor and its sensing technologies, a series of technical considerations and resultant improvements have been done on the sensor as a key component of near future Si-integrated microsensor system. The technical developments are started from immobilization of minute droplet of liposome suspension and intact supramolecule structure. Moreover, new biosensing systems of liposome impedance biosensor and fluorescence array sensor are developed, based on electronics techniques. Finally, the sensitivities and performance of both leakage current sensor and cantilever strain sensor are improved because a resultant quantitative capability of immobilization of minute liposome droplet on the sensor becomes improved. We also note that the impedance sensor can detect the interaction between the liposome and target protein with a 100 nL order. And that the fluorescence array sensor system can discriminate different target biomolecules.
