Whole-cell biochips for online water monitoring

CONDUCTIVITY CELL FOR wATER QUALITY mONITORING

The measurement of electrolytic conductivity is widely applied as a control parameter and its relevance is continuously increasing, not only in industrial applications but also in the environmental monitoring domain. In this work the attention is focused on the electrical behaviour of a low cost in-situ four electrode conductivity sensor for water quality monitoring in estuaries and oceans. The...

Water pollutant monitoring by a whole cell array through lens-free detection on CCD.

Environmental contamination has become a serious problem to human and environmental health, as exposure to a wide range of possible contaminants continuously increases due to industrial and agricultural activities. Whole cell sensors have been proposed as a powerful tool to detect class-specific toxicants based upon their biological activity and bioavailability. We demonstrated a robust toxican...

Bioluminescent Whole-cell Biosensor for On-line Water Toxicity Detection

We present a novel microbial whole-cell sensing system for biodefense and environmental pollution monitoring. Real time water toxicity monitoring is achieved using genetically engineered E. coli bioluminescent cells which emit light when exposed to toxic materials. The illumination intensity and its time dependence are a function of the toxicants dose and type. The bacteria are immobilized in a...

Online Monitoring the Water Contaminations with Optical Biosensor

This work presents a demonstrator for online monitoring of pesticides or water contaminants which is robust, fast, specific and low cost. The system is designed for continuous monitoring in water matrices (sourceand surface water, treated waste water), and is thus completed with an automated fluidics. The main characteristics of the system are: (a) Detection based on competitive immunoassay; (b...
