Tissue engineering skeletal muscle in vitro is of great importance for the production of tissue-like constructs for treating tissue loss due to traumatic injury or surgery. However, it is essential to find new sources of cells for muscle engineering as efficient in vitro expansion and culture of primary myoblasts are problematic. Mesenchymal stem cells may(More)
As the principle structural polysaccharide in plants, cellulose has been extensively characterized over many decades. In recent years, however, exciting new cellulosic materials have been developed with nanoscale fibrillar structures that have particularly promising applications in the growing field of tissue engineering. The majority of recent studies on(More)
Cellulose nanowhiskers (CNWs) are high-aspect-ratio rod-like nanoparticles prepared via partial hydrolysis of cellulose. For the first time, CNWs have been extracted from the marine invertebrate Ascidiella aspersa, yielding animal-derived CNWs with particularly small diameters of only a few nanometres. Oriented surfaces of adsorbed CNWs were prepared using(More)
Radially oriented submonolayer surfaces of 10-15 nm diameter cellulose nanowhiskers (CNWs) were prepared by spin-coating. The response of myoblasts (muscle cells) to the surfaces was assessed using atomic force microscopy (AFM), immunocytochemistry, and image analysis. Despite the small size of the CNWs, the myoblasts oriented along the CNW surfaces. Upon(More)
In this study, we report the production of amine functionalized nanodiamond. The amine functionalized nanodiamond forms a conformal monolayer on a negatively charged surface produced via plasma polymerization of acrylic acid. Nanodiamond terminated surfaces were studied as substrates for neuronal cell culture. NG108-15 neuroblastoma-glioma hybrid cells were(More)
Diamond-like carbon (DLC) was modified using a UV functionalization method to introduce surface-bound amine and aldehyde groups. The functionalization process rendered the DLC more hydrophilic and significantly increased the viability of neurons seeded to the surface. The amine functionalized DLC promoted adhesion of neurons and fostered neurite outgrowth(More)
A detailed analysis of dispersion-compensating fiber-optic filter is provided. Design parameters of the filter that could provide dispersion compensation for wide spectral sources are discussed. The dispersion-compensating fiber filter designed here can be dynamically tuned to compensate for the drift in the laser center frequency caused by temperature(More)
Porous composites containing hydroxyapatite (HA) were templated from high internal phase emulsions (HIPEs) and were further structured using direct-write UV stereolithography to produce composite scaffolds with multi-scale porosity. FTIR, TGA and SEM analyses confirmed that HA was retained after photocuring and subsequent treatments and was incorporated(More)
A simple, unidimensional, thin-layer-chromatographic separation of amniotic fluid phospholipids involving detection with a phosphorus-specific spray was compared to the two-dimensional, thin-layer-chromatographic method described by Gluck et al. There were close correlations between the two techniques for lecithin/sphingomyelin ratios and for the presence(More)
