Nano Sensors to Treat Wastewater: A Review

Prashant Agarwal, Ritika Gupta


A consistent clean water supply is crucial to a stable and healthy population. However, human development and population growth are depleting the already limited clean drinking water source. Nowadays, water pollution significant jeopardizes the continuous clean drinking water supply that results in the damage of human health, and economy development. Many efforts have been made to develop portable sensors for monitoring heavy metals, pathogen microorganisms in the wastewater. Incorporation of nanomaterials and nanostructures into sensors leads to significant improvement in the performance of devices in terms of sensitivity, selectivity, multiplexed detection capability and portability. This review presents wastewater microbiological pollution monitoring by detecting of volatile organic compounds released from the metabolism of pathogenic microorganisms, that typically contaminate water.
