Optofluidic Sensing

Conventional optical spectroscopy and imaging systems are large, complex and costly optoelectronic instruments comprised of lasers, spectrophotometers, and detectors. Often, their size is the limiting factor for their use in certain applications such as in-situ monitoring of physiological processes and distributed environmental sensing. In practice, there are strong demands for miniaturized, integrated devices for biomedical applications.

Recent advances in micro-photonics and electronic devices have led to small but efficient components/modules. These technologies are mostly built upon well-established microelectronic technologies for integrated circuitry. When conventional devices are replaced with micro-components, new applications and capabilities can be facilitated. Moreover, it usually leads to significant cost reductions and increases in yield associated with mass production.

The overall objectives of this project area include (i) develop novel micro-optical sensing and imaging device technology with spectrally- and temporally-resolved optical signal acquisition; (ii) investigate the integration and packaging of complete sensing/imaging devices; and (iii) study the applications of such devices in biomedical and environmental applications. The proposed program will be based on the Micro/Nano Systems Lab and focus on integrated device technology development. Its success will allow translation of such technology to applications in biomedical diagnosis, drug discovery, and environmental monitoring.
