Resumen:
Anthropic activities generate contaminants, as pesticidesand other pollutants, in the aquatic environment whichpresent a real threat to ecosystems and human health. Thus,monitoring tools become essential for water managers to detectthese chemicals before the occurrence of adverse effects.In this aim, algal cell biosensors, based on photosystem IIactivity measurement, have been designed for several yearsin previous studies. In this work, we study a new immobilizationtechnique of algal cells in the aim of improving the performanceof these biosensors. Immobilization was hereachieved by encapsulation in a hybrid alginate/silicatranslucid hydrogel. The feasibility of this process was hereassessed, and the biosensor designed was tested on the detectionof chemicals in urban rainwaters
