Here we present two types of all-printable, highly stretchable, and inexpensive devices based on platinum (Pt)-decorated graphite for glucose determination in physiological fluids. Said devices are: a non-enzymatic sensor and an enzymatic biosensor, the latter showing promising results. Glucose has been quantified by measuring hydrogen peroxide (H2O2) reduction by chronoamperometry at -0.35 V (vs pseudo-Ag/AgCl) using glucose-oxidase immobilized on Pt-decorated graphite. The sensor performs well for the quantification of glucose in phosphate buffer solution (0.25 M PBS, pH 7.0), with a working range between 33 μM and 0.9 mM, high sensitivity and selectivity, and a low limit of detection (LOD). Thus it provides an alternative non-invasive and on-body quantification of glucose levels in human perspiration. This biosensor has been successfully applied on real human perspiration samples and results also show a significant correlation between glucose concentration in perspiration and glucose concentration in blood measured by a commercial glucose meter.

Microstructured materials are becoming important for high performance electrochemical device especially for energy storage due to their advantageous diffusion and flux properties. Utilizing a rationally designed hollow structured polypyrrole microparticles (PPyMPs) with controllable wall thicknesses of -110 to 340 nm, we observed a significant morphological effect on electrocapacitive kinetics of the PPyMPs modulated by the voltammetric potential window and scan rate. The thinhollow architecture of PPyMPs revealed significant enhancement of charge storage performance (up to 447%), high retention at high scan rate and faster charge/dis-charge kinetics compared to the thick-hollow PPyMPs due to the larger accessible surface area and decrease of diffusion length. These findings demonstrated the electrocapacitive kinetics performance of microstructured soft materials related to morphological effect modulated by operational conditions. Our study provides new insight on electrochemistry of soft electrode materials with controlled nanostructured morphology for understanding the mechanism of charge insertion and mass diffusion for the future development of high performance porous electrode material.

“…The sacrificial CaCO3 template guided the polymerization process to yield homogenous PPyMPs with a narrow size distribution. The porous nature of the CaCO3 further allows the incorporation of various organic and inorganic dopants such as an electro catalyst and redox mediator for the fabrication of functional PPyMPs [24]. A comparative study by Cardoso et al reported in Enzymatic Biofuel Cells as a biocathodes with species, namely porphyrin, ferrocene, osmium, and ruthenium complexes on immobilized carbon platforms entrapped in an electropolymerized polypyrrole matrix.…”

The involvement and development of intelligent polymers in enzymes as a catalyst have been interesting to develop processes that are environmentally benign, energy efficient, and selective towards their specific molecular applications. Polypyrrole based enzyme nanocomposites represents a continuous considerable redox organic polymer that have been increased in electromechanical devices in advance for surface functionalization. This review addresses the fundamental concepts of polypyrole and its composites role for enzyme immobilizing functioning and its bio functional bioelectrocatalytic system operating principle in biosensor and biofuel cells as well as its involvement in electron transfer mechanism as a bio electrode to create an advanced bioelectronics device from power generating system to extreme analyte detecting system.
