METHOD AND APPARATUS FOR ENHANCED DETECTION OF TOXIC AGENTS
First Claim
1. A method of biosensor-based detection of toxins, comprising the steps of:
- concentrating a plurality photosynthetic organisms in a fluid to be analyzed into a concentrated region using biased AC electro-osmosis;
obtaining a measured photosynthetic activity of said photosynthetic organisms in said concentrated region, wherein chemical, biological or radiological agents reduce a nominal photosynthetic activity of said photosynthetic organisms, anddetermining a presence of at least one of said chemical, biological or radiological agents, or precursors thereof, in said fluid based on said measured photosynthetic activity.

Abstract
A water quality analyzer for real-time detection according to the invention comprises a biased AC electro-osmosis (ACEO) cell for receiving a fluid to be analyzed having a plurality photosynthetic organisms therein, and concentrating the plurality photosynthetic organisms into at least one concentrated region. A photodetector is provided for obtaining a measured photosynthetic activity of the plurality of photosynthetic organisms in the concentrated region: wherein chemical, biological or radiological agents reduce a nominal photosynthetic activity of the photosynthetic organisms. An electronics package analyzes the measured photosynthetic activity to indicate a presence of the chemical, biological or radiological agents in the fluid.
