Fig. 3: Analysis of BioGel interactions and oxygen diffusion on platinum surfaces.
A Proposed chemical structure for the BIL cation and its counterion (bitartrate), alongside the chemical structure of GelMA and an example of the simulation setup employed to analyze the properties of the BioGel on the [111] surface of platinum. B Computed radial distribution functions (RDFs) for the distribution of oxygen molecules on the platinum surface in the presence of GelMA at concentrations of 7 wt% and 20 wt%, respectively, in complexation with varying concentrations of the BIL. C Calculated interaction energies between O2 molecules and the platinum surface in the presence of BioGel with various GelMA-BIL mixtures, indicating potential changes in interaction strength with different BIL concentrations. D The calculated diffusion coefficients of oxygen molecules within the BioGel matrices containing 7 wt% and 20 wt% GelMA highlight the influence of GelMA concentration on the mobility of O2 molecules.
