CD-ROM based optical biosensors
First Claim
1. An optical biosensor for detecting a targeted biological sample in air, the optical biosensor comprising:
- a.) a CD-ROM, the CD-ROM including a plurality of data blocks raised from the surface of the CD-ROM, the plurality of data blocks configured spirally around the center of the CD-ROM;
b.) a receptor medium, configured to coat the surface of the CD-ROM such that the receptor medium binds with the targeted biological sample; and
c.) a reader, configured to read the plurality of data blocks of the CD-ROM, and further configured to detect the targeted biological sample when the targeted biological sample binds with the receptor medium, wherein the targeted biological sample obstructs the reader from reading the plurality of data blocks, further wherein the reader is configured to output a recognizable signal.

Abstract
A CD-ROM based optical biosensor, system and method of sensing biological samples in the air includes treating the surface of a CD-ROM medium with a receptor capable of binding with a targeted biological sample. While continuous reading of the CD-ROM is conducted by a CD-ROM drive, an air-flow is directed through the CD-ROM drive, over and around the CD-ROM such that any targeted biological samples present in the air will bind with the receptors. The laser reader of the CD-ROM device detects these biological samples as they obstruct the data blocks present on the CD-ROM. A processor of the CD-ROM drive determines whether an output signal is required, and if so, appropriately sends one to an output device.
