Optical Microcavity Analysis (OMCA) promises:
- Orders of magnitude increase in the sensitivity of optical sensing methods
such as colorimetric absorption assays.
- Measurement using only minute liquid sample volumes, making precious
samples last longer and simplifying sample collection processes.
- Sensor elements that are microns in size and highly parallelizable,
compatible with microfluidic systems and chip-scale devices.
The technology represents a universal platform for chip-scale chemical and nanoparticle sensing. Sensors can be configured to detect a wide range of chemical and particle species of interest, from heavy metal pollutants to micron sized particles such as bacteria.
