Abstract
A compact integrated biosensor has an integrated light source and integrated optical detectors made with gratings, dielectric coating, or prism for specific wavelength selection to define signatures that identify elements, biohazardous materials, environmentally hazardous materials, biological substance or any chemical substance on the sample holders. A micropump draws gas, ambient fluids and samples to the sample holders. Electrical signals are provided from the optical detectors on output lines to the microprocessor. A device connected to the microprocessor compares characteristic responses to actual signal parameters. An output indicates the presence (or absence) of particular biological, chemical or environmentally hazardous material. A battery, fuel cell or solar cell operated power supply provides electrical energy to the integrated light source and optical detectors. An ambient detector may provide a sample and hold memory for later releasing qualitative and quantitative information concerning the biosensor's environment and environmental history. Output of the biosensor may be continuous, periodical or on demand, or connected to a read-out device. The biosensor is usable as a badge by personnel or is attached to vehicles or mobile or stationary equipment, or to remote collection vehicles such as drones.
