“…The biosensor also has integrated microfluidic technology built on an easily accessible 3D printer and cost-effective electronics. The transducer and Arduino board have been validated in both chemical and biomedical contexts [27,28]. Commercial laboratory spectrophotometers, which were used for validation in this study, employ a xenon light source and a temperature control system, enabling measurements with high accuracy and precision, but at higher costs.…”

Overweight and obesity promote diabetes and heart disease onset. Triglycerides are key biomarkers for cardiovascular disease, strokes, and other health issues. Scientists have devised methods and instruments for the detection of these molecules in liquid samples. In this study, an enzymatic biosensor was developed using an Arduino-based microfluidic platform, wherein a lipolytic enzyme was immobilized on an ethylene-vinyl acetate polymer through physical adsorption. This low-cost optical biosensor employed a spectrophotometric transducer and was assessed in liquid samples to indirectly detect triglycerides and fatty acids using p-nitrophenol as an indicator. The average triglyceride level detected in the conducted experiments was 47.727 mg/dL. The biosensor exhibited a percentage of recovery of 81.12% and a variation coefficient of 0.791%. Furthermore, the biosensor demonstrated the ability to detect triglyceride levels without the need for sample dilution, ranging from 7.6741 mg/dL to 58.835 mg/dL. This study successfully developed an efficient and affordable enzymatic biosensor prototype for triglyceride and fatty acid detection. The lipolytic enzyme immobilization on the polymer substrate provided a stable and reproducible detection system, rendering this biosensor an exciting option for the detection of these molecules.

“…Currently, urine has been considered a biomarker source for cancer detection, urine tract infections, kidney diseases, glucose levels, in ammatory biomarkers for chronic diseases, preeclampsia in pregnancy, etc. [5][6][7][8][9][10][11][12][13][14][15]. However, urine could also be used as fuel in electrochemical devices (fuel cells), which could be implemented as power sources on LOC devices.…”

Urine has recently been considered a source of novel biomarkers for early disease detection; developing more autonomous medical devices would be possible if the urine is also used as fuel in microfluidic fuel cells. This work presents a paper-based microfluidic fuel cell that operates, for the first time, with diabetic urine. Diabetic urine has a different composition than normal urine, and some molecules could affect urea oxidation and decrease fuel cell power generation. This work shows a selective catalyst of ZnO and nickel-based particles used as anode in a paper-based microfluidic fuel cell. Catalysts with different concentrations of Ni+2 were evaluated. The best results were obtained with 3% nickel, using diabetic urine; the maximum voltage achieved was 0.89 V, with a maximum current density of 1.18 mA cm-2 and a maximum power density of 1.26 mW cm-2.
