The aim of this study is to use EPR SDSL for study the binding of methemoglobin on bioactive glass surfaces. EPR spectra recorded in solution can be compared directly to those obtained after adsorption to extract structural information. A consistent analysis of EPR spectra revealed that the adsorption of methemoglobin is influenced by the chemical composition of the bioactive glass. A fitting of the different spectral components was carried out, addressing the possible origin of those components. |
