X-ray spectromicroscopy study of competitive adsorption of protein and peptide onto polystyrene-poly(methyl methacrylate).
A synchrotron-based x-ray photoemission electron microscope (X-PEEM) was used to investigate the coadsorption of a mixture of human albumin serum and SUB-6, a synthetic antimicrobial peptide, to a phase-segregated polystyrene/poly(methyl methacrylate) (PMMA) substrate at varying concentrations and pH. The authors show that X-PEEM could detect the peptide adsorbed from solution at concentrations...
متن کاملImaging hydrated albumin on a polystyrene-poly(methyl methacrylate) blend surface with X-ray spectromicroscopy.
Human serum albumin (HSA) adsorbed to thin films of phase-segregated polystyrene (PS)-poly(methyl methacrylate) (PMMA) was examined under hydrated and dry environments with scanning transmission X-ray microscopy (STXM). Quantitative mapping of the protein and polymer components at 30 nm spatial resolution was achieved using near-edge X-ray absorption fine structure (NEXAFS) spectral contrast at...
متن کاملX-Ray Absorption Spectromicroscopy of Aqueous Samples
X-ray PhotoElectron Emission Microscopy (X-PEEM) has found numerous applications in the surface microchemical analysis of materials science and biological specimens. We have reconfigured the MEPHISTO X-PEEM instrument, installed at the UW-Synchrotron Radiation Center, to measure true x-ray transmission spectra by converting transmitted photons to photoelectrons via a thin photocathode layer of ...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
15 صفحه اولCluster analysis of soft X-ray spectromicroscopy data.
Soft X-ray spectromicroscopy provides spectral data on the chemical speciation of light elements at sub-100 nm spatial resolution. When all chemical species in a specimen are known and separately characterized, existing approaches can be used to measure the concentration of each component at each pixel. In other cases (such as often occur in biology or environmental science), some spectral sign...
