Lateral flow assay HIV-based microfluidic blood fuel cell

This work presents the integration, evaluation and performance of a lateral flow assay HIV-based microfluidic fuel cell. To integrate the microfluidic fuel cell, a Pt/C cathode and Au/C anode were deposited on Toray® paper and stacked on the top and bottom, respectively, of the paper strip lateral flow assay HIV. According to the microfluidic fuel cell evaluation, the Pt/C cathode reduces the oxygen delivered from air, meanwhile the Au/C anode oxidizes the glucose contained in the human blood. The lateral flow assay HIV-based microfluidic blood fuel cell (LFA HIV-based μBFC) performance showed power density of 0.15 mW cm-2. The open circuit voltage and maximum current density were 0.57 V and 1.2 mA cm-2, respectively. Furthermore, the LFA HIV-based μBFC showed a constant current density for 10 minutes at a potential corresponding to the maximum power density. In this sense, is demonstrated that lateral flow assay towards an autonomous energy device is a great advance to be applied in point-of-care testing.
