“…This potential for integration is promising for analysis of water‐based substances such as urine, blood, or groundwater. In particular, combining the MFC with an electrochemical sensor shows the most promise . For example, amperometric glucometers have been developed that use only 1.1 mA of current from a 3.0 V button cell battery for rapid blood glucose analysis .…”

We describe the first direct formate fuel cell on a paper microfluidic platform. In traditional membrane-less microfluidic fuel cells (MFCs), external pumping consumes power produced by the fuel cell in order to maintain co-laminar flow of the anode stream and oxidant stream to prevent mixing. However, in paper microfluidics, capillary action drives flow while minimizing stream mixing. In this work, we demonstrate a paper MFC that uses formate and hydrogen peroxide as the anode fuel and cathode oxidant, respectively. Using these materials we achieve a maximum power density of nearly 2.5 mW/mg Pd. In a series configuration, our MFC achieves an open circuit voltage just over 1 V, and in a parallel configuration, short circuit of 20 mA absolute current. We also demonstrate that the MFC does not require continuous flow of fuel and oxidant to produce power. We found that we can pre-saturate the materials on the paper, stop the electrolyte flow, and still produce approximately 0.5 V for 15 min. This type of paper MFC has potential applications in point-of-care diagnostic devices and other electrochemical sensors.

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting galley proof before it is published in its final citable form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. AbstractThe syntheses of hexadecylamine seed mediated Ag/M(M = Co, Ni, Pd and Pt) allied nanobimetallic particles were successfully carried out by the successive reduction of ligand capped metal ions with polyols, resulting in concomitant precipitation of some high index faceted hybrid Ag/M bimetal nanoparticles. The optical measurements revealed the existence of surface plasmon band and peak broadening that causes diffusion processes of the metal sols to decrease making it possible to monitor the changes spectrophotometrically. The bimetallic nanoparticles were characterized by X-ray diffraction, X-ray photoelectron spectroscopy and electron microscopy techniques which confirm the formation of alloyed clusters.

“…Microfluidic devices may incorporate electrodes for chemical or biological sensing [1][2][3][4][5][6][7], for particle separations [7][8][9], to drive electroosmotic flow [10,11], or for power generation in microfluidic fuel cells [12][13][14][15][16][17]. In a microfluidic system, electrodes must be fabricated to interface properly with other device features and functionalities.…”

“…Poor biocompatibility of carbon black may also be problematic for certain applications. In several reports, Arriaga and coworkers spray-coated a conductive ''ink'' along the side walls of millimeter-scale channels hot embossed into poly(methyl methacrylate) [14][15][16][17]. However, successful implementation of spray coating techniques into sealed microchannels may prove challenging.…”
