Abstract: Biosensors were introduced for the first time by Clark and Lyons in 1962 [1], which developed a biosensor based on the immobilization of glucose oxidase enzyme on an oxygen electrode for the measurement of glucose concentration in biological fluids. Since then, constant research and development efforts have been undertaken in biosensor technology for in field application in areas as agrifood and environmental control, as well as in biomedical diagnosis and biodefence. Among them, algal biosensors also demonstrated their huge potential as sensitive tools for the environmental protection [2-4]. Herein, an overview of algal biosensors as well as systems developed in the last years exploiting different bioreceptors (e.g. enzymes, biomimetics), transductions systems (e.g. fluorescence, electrochemistry), supports (screen-printed electrodes, paper), and nanomaterials (e.g. carbon black, quantum dots) [5] was reported.
