Optical biosensor for the rapid detection of protein toxins and other biological pathogens
This sensor platform will be used for a variety of medical diagnostic issues.
- early diagnosis of infection
- early diagnosis of breast and other cancers
- monitoring of signature antigens to track treatment
- development of broad spectrum protein arrays to screen for disease (e.g., antibody arrays)
- sensitive detection of signature antigens to track disease progression
- environmental monitoring, bio-threat detection, food inspection and industrial uses
- Ultra-high sensitivity and specificity
- Simple use—one step with no reagents required
- Fast detection times
- Adapted to planar optical waveguides to facilitate miniaturization
- Low power consumption and lightweight
- Inexpensive, replaceable sensor elements
- Suitable for use in a point-of-care facility
An optical biosensor has been developed for the rapid detection of protein toxins and other biological pathogens. The sensor platform is extremely flexible and has been adapted for use with virtually any recognition molecule. Accordingly, this sensor can be used to detect any signature biomolecule. Although originally developed to address needs in environmental detection of bio threat agents, this sensor system can and is being adapted for use in medical diagnostics. In particular, current efforts include the development of this sensor system for the detection of viruses (including influenza and hantavirus), bacterial infections (e.g., tuberculosis), protein toxins (e.g., staph enterotoxin B), and tumor specific antigens for the early diagnosis of cancer (CEA, her-2-neu etc.).
Development Stage: The optical biosensor has been prototyped and the protoype has been demonstrated.
