The anthropic activities generate contaminants, as pesticides and other pollutants, in the aquatic environment which present a real threat to ecosystems and human health. Thus, monitoring tools become essential for water managers to detect these chemicals before the occurrence of adverse effects. In this aim, algal cell biosensors, based on photosystem II activity measurement have been designed for several years in previous studies. In this work we study a new immobilization technique of algal cells in the aim of improving the performance of these biosensors. Immobilization was here achieved by encapsulation in hybrid alginate/silica translucide hydrogel. The feasibility of this process was here assessed and the biosensor designed was tested on the detection of chemicals in urban rain waters.
