Abstract

It is imperative that the impurities in our air and water are polluting the environment. Growing concern on phenolic, micro and macro pollutants has created the need for a technological platform for researchers to come up with advanced bio-analytics like biosensors for monitoring them. National and International standards have put down stringent standards for phenol and its derivatives in wastewater knowing its toxicity and persistent presence in wastewater. Enzyme biosensors have been very promising in quantifying phenolic compounds with great precision and accuracy since last few decades. Oxidoreductases like tyrosinase, peroxidase, and laccase are engaged as bioreceptor in phenol quantifications. Present review gives a concise state of laccase amperometric biosensors for phenol quantification as a green technique for today's world, highlighting its sensitivity.
