Determination of phosphorus in water and chemical fertilizer samples using a simple drawing microfluidic paper-based analytical device
A simple one-step drawing for the cost-effective fabrication of microfluidic paper-based analytical devices (µPADs) for the determination of phosphate content in water and fertilizer samples is presented in this paper. The hydrophobic barrier of µPAD was patterned using a 2-mm tip marker pen using a...
