Polystyrene Petri dishes, aminated by a plasma deposition process, were surface modified by the covalent linking of two different enzymatically modified hairy regions (HRs) from pectin containing, for example, rhamnogalacturonan-I and xylogalacturonan structural elements. The two polysaccharide preparations share the same structural elements of apple(More)
Two different types of carbon coatings for cardiovascular applications were characterized both as regards to their physico-chemical properties and blood compatibility upon contact with human plasma and platelets. The samples were analyzed by means of a wide range of techniques, including scanning electron microscopy (SEM) and atomic force microscopy (AFM),(More)
Development of biomaterial-related infections is attracting an increasing interest due to the significant percentage of implant failure in the hospital care. Recent literature puts in evidence the dependence of the infection risk on the different biomaterials used, because of the different interactions between material surface and micro-organisms. Despite(More)
Synthetic implant materials often lack of the anisotropic mechanical properties and cell-interactive surface which are shown by natural tissues. For example, engineered vascular grafts need to be developed to address the mechanical and biological problems associated with the graft materials. This study has demonstrated a double-electrospinning fabrication(More)
Nanometric silk-fibroin nets were fabricated by electrospinning from regenerated Bombyx mori silk-fibroin (SF)/formic acid solutions with the addition of genipin (GE), 2, 15 and 24 h after the solution preparation. After spinning, the pure fibroin nanofibers were water soluble and needed a further stabilization process, whereas the reaction of fibroin with(More)
The aim of this study was to determine the relationships between the surface properties and blood compatibility of in-use diamond-like carbon (DLC) coatings for cardiovascular components. Commercially available DLC films were characterized with respect to surface topography and wettability, protein adsorption from human plasma, and platelets(More)
The acid-base approach to the calculation of solid surface free energy and liquid-liquid interfacial tensions is a practical example of application of correlation analysis, and thus it is an approximate approach. In these limits, and provided that wide and well-obtained sets of contact angles or interfacial tension data are used for their computation,(More)
In the topological approach to structure-property relationships, the molecular structure is described in terms of appropriate weighted graphs to which suitable topological parameters, usually known as molecular connectivity indices, can be associated. Molecular connectivity indices are here applied to the prediction of surface free energy and Good-van(More)
In this article, we propose a systemic approach to investigate the impact of electrohydrodynamic jetting (EHDJ) encapsulation on viability, proliferation, and functionality of the encapsulated cells. EHDJ consists in applying a high-voltage electrical field between a target substrate and a jetting needle, which is fed with a suspension of cells in a(More)
The purpose of the current study was to develop and optimize novel self-nanoemulsifying drug delivery systems (SNEDDS) with a high proportion of essential oil as carriers for lipophilic drugs. Solubility and droplet size as a function of the composition were investigated, and a ternary phase diagram was constructed in order to identify the(More)
