Using carefully designed plasmonic and photonic substrates and unique reading methodology, a group of miniature optical biosensors are being developed with ultralow detection limit. The different concepts involve the following:
- Plasmonic substrate with improved penetration depth for detecting large bioentities such as bacteria in water.
- LED or LD based biosensor combined with camera, fast algorithm, and piezoelectric micropump allows miniaturization, multiple channel sensing, and low power consumption.
- Self-referenced grating based optical biosensors with ease of fabrication methodology in large areas.
- SERS and SEF substrates with ultra-large enhancement factors allowing ultra-low detection limit.
- An integrated multi-modal optical biosensing system that includes several of the technologies mentioned above in one platform, thus increasing the reliability.
