摘要：

Whole cell based biosensor is prepared by immobilizing Chlorella sp. microbes over glassy carbon electrode. The proposed biosensor is optimized for characteristics like substrate concentration, pH, response time, and durability. The electrode responds linearly in concentration range of 10(-14) M to 10(-6) M for mercury and showed its rare selectivity over silver, alkali metals, alkaline earth metals and transition metals with an expected life of 14 days.
