Review on Microfluidic Paper Based Analytical Devices (µPADs) and Possible Application by Employing Waste Paper
Keywords:µPADs, enzymatic treatment, waste paper, metal ions and colorimetric
Microfluidic paper-based analytical devices (µPADs) has been broadly used and gained many researchers attention for clinical medicine and health, food quality inspection and environmental analysis. Qualitative analysis on several related articles managed to review the development of µPADs and as a result the proposal on its fabrication techniques by using waste paper for the application in environmental analysis through colorimetric detection is determined. The deinking process of waste paper can be carried out by using enzymatic treatment while the fabrication of µPADs can be carried out by using wax printing technique. Therefore, the device is subjected to be tested with detection of metal ions from water sample through colorimetric detection
