Preface to Forum on “Current Trends in Functional Surfaces and Interfaces for Biomedical Applications” his ACS Applied Materials & Interfaces Forum is based on the Symposium on Functional Surfaces and Interfaces, within the Organic and Bio-Materials Section at the Spring 2015 European Materials Research Society meeting in Lille, France. The symposium was organized by Laura Treccani (University of Bremen), Giovanni Marletta (University of Catania), and Patrick van Rijn (University of Groningen). The Forum articles describe how the surface properties of a variety of materials can be optimized to perform various functions in a biological environment. The applications vary from sensing to directly affecting mammalian cell development. In their Spotlight on Applications article, Ventre and Netti review recent work on material-induced cell responses with potential applications including prosthesis design, tissue engineering, diagnostics, and stem cell biology. The Forum Article by Addadi et al. describes an innovative correlative imaging method to image the same area of bone using three different microscopy techniques to study the adhesion of osteoclasts to cortical bone surfaces. Alessandri et al. show how combining SiO2/TiO2 microbeads with tetraphosphonate cavitands imparts selectivity toward Nε-methylated lysine, which can then be detected by surface enhanced Raman scattering. Jenkins et al. report the development of a wound dressing containing a florescent-dye impregnated hydrogel that fluoresces to indicate early detection of bacterial infection. Lavalle et al. use experiments and molecular dynamics simulations to investigate the effect of stress on the secondary structure of cross-linked poly(L-lysine)/hyaluronic acid (PLL/ HA) multilayers. They postulate that the reversible stretchinduced conformational changes in films could be used to control drug release or catalytic activity. Kelleher et al. report an interesting dependence of the biocidal properties of cicada wings on the scale of the nanostructure of the wing surface. Cipolla et al. show how sialylated collagen films can influence the gene expression in mesenchymal stem cell toward osteogenesis or chondrogenesis. D’Sa et al. investigate the response of human fetal osteoblast cells (hFOBs) to changes in the topology and chemistry (hydrophobicity) of poly(methyl methacrylate)/polystyrene demixed thin film blends. We believe that this Forum brings together some of the most innovative applied research on functional surfaces and interfaces for biomedical applications that emerged from the 2015 E-MRS symposium, and thank the authors for their contributions.
