Abstract
The illustrated embodiment comprises a biosensor utilizing plant cells and nutrient media for maintaining the plant cells in a live condition. A light source having desired optical characteristics is directed onto the plant cells and light spectra transmitted from the cells is detected by a photodetector. A controller analyzes signals from the photodetector to detect a state change in the plant cells in response to exposure to an agent.
