Emerging Technologies for Next-Generation Point-of-Care Testing. (2015, unknown): “Another example is the fabrication of microfluidic paper-based electrochemical devices (mPEDs) by printing electrodes on paper (Figure 2C) for the detection of nucleic acids, alcohol, uric acid, cholesterol, lactate, and glucose [46,61].”
Advances in paper-based point-of-care diagnostics. (2014, methodology): “To ensure sufficient sensitivity of the electrochemical reactions, materials such as AuNPs, carbon nanotubes and/or grapheme nanosheets, are employed to modify the working electrode (Lu et al., 2012; Wang et al., 2012a; Yan et al., 2012).”
Fabrication techniques for microfluidic paper-based analytical devices and their applications for biological testing: A review. (2016, methodology): “Besides, Lu et al. (2012) also introduced an electrochemical DNA sensor into a folding paper-based on the AuNPs/grapheme modified screen-printed on the working paper electrode before.”
