Transition metal (Fe, Ni, Co)-based hydroxides, especially nickel hydroxide (Ni(OH) 2 ), have been considered as promising candidate for hydrogen evolution reaction (HER) because of their low cost, natural abundance and high catalytic performance. However, the catalytic performance of Ni(OH) 2 is still unsatisfactory for practical application due to its relatively low electrical conductivity. Here, a highly conductive silver nanowires (AgNWs) network is prepared on filter paper, followed by the electrodeposition of Ni(OH) 2 on the surface of AgNWs to form AgNWs@Ni(OH) 2 core-shell structure. In comparison with pure Ni(OH) 2 (376 mV at −10 mA cm −2 ), the optimized AgNWs@Ni(OH) 2 electrode can exhibit about 3-fold enhanced HER performance, which achieves a lower overpotential of 123 mV at the current density of −10 mA cm −2 , and a small Tafel slope of 76 mV dec −1 in 1 M KOH electrolyte. Besides the superior activity, the AgNWs@Ni(OH) 2 electrode also shows a better durability. Such enhanced catalytic performance benefits from the high conductivity of AgNWs network to facilitate electron transfer, and the synergistic interaction between AgNWs and Ni(OH) 2 . This work also provides general strategies to design highly active HER electrocatalysts by utilizing highly conductive AgNWs to form core-shell architecture.

Microfluidic Paper-Based Blood Plasma Separation Device as a Potential Tool for Timely Detection of Protein Biomarkers

et al. 2022

A current challenge regarding microfluidic paper-based analytical devices (µPAD) for blood plasma separation (BPS) and electrochemical immunodetection of protein biomarkers is how to achieve a µPAD that yields enough plasma to retain the biomarker for affinity biosensing in a functionalized electrode system. This paper describes the development of a BPS µPAD to detect and quantify the S100B biomarker from peripheral whole blood. The device uses NaCl functionalized VF2 filter paper as a sample collection pad, an MF1 filter paper for plasma retention, and an optimized microfluidic channel geometry. An inverted light microscope, scanning electron microscope (SEM), and image processing software were used for visualizing BPS efficiency. A design of experiments (DOE) assessed the device’s efficacy using an S100B ELISA Kit to measure clinically relevant S100B concentrations in plasma. The BPS device obtained 50 μL of plasma from 300 μL of whole blood after 3.5 min. The statistical correlation of S100B concentrations obtained using plasma from standard centrifugation and the BPS device was 0.98. The BPS device provides a simple manufacturing protocol, short fabrication time, and is capable of S100B detection using ELISA, making one step towards the integration of technologies aimed at low-cost POC testing of clinically relevant biomarkers.
