Water quality monitoring system based on microfluidic device

Water is one of the basic necessities in life. In Malaysia, Ammonia NH3 is found to be one of the main causes of water pollution according to Jabatan Alam Sekitar (JAS). To minimize this issue, this paper proposes an alternative way to detect ammonia content in the river using a microfluidic device....
