“…It has been shown that the size and surface topology of monofilament fibers can modulate the orientation and organization of cells . Cells have shown to respond to the surface morphologies in nano‐ and microscales . For instance, cells grown on PLGA fibers were mostly aligned along the fiber axis when seeded on smaller diameter fibers (<30 μm) ( Figure ) .…”

Textile technologies have recently attracted great attention as potential biofabrication tools for engineering tissue constructs. Using current textile technologies, fibrous structures can be designed and engineered to attain the required properties that are demanded by different tissue engineering applications. Several key parameters such as physiochemical characteristics of fibers, pore size and mechanical properties of the fabrics play important role in the effective use of textile technologies in tissue engineering. This review summarizes the current advances in the manufacturing of biofunctional fibers. Different textile methods such as knitting, weaving, and braiding are discussed and their current applications in tissue engineering are highlighted.

“…In the literature, topography [43,45,64,65], surface energy [39], plasma treatment [12,24,33,40], surface termination with functional groups [41,42] and electronic charge were shown to influence cell attachment. Parikh et al [43] have investigated the influence of different surface morphologies, including smooth surfaces, islands, connected islands and pits on the attachment of SK-N-SH neuroblastoma endothelial cells based on self-assembly of gadolinium-doped ceria on yttria-stabilized zirconia substrates (GDC/YSZ). Increased attachment on pits and connected islands were observed and indicated that a higher feature area was a major determining factor.…”

Ultrananocrystalline diamond (UNCD) has been demonstrated to have attractive features for biomedical applications and can be combined with nanoporous membranes for applications in drug delivery systems, biosensing, immunoisolation and single molecule analysis. In this study, free-standing nanoporous UNCD membranes with pore sizes of 100 or 400 nm were fabricated by directly depositing ultrathin UNCD films on nanoporous silicon nitride membranes and then etching away silicon nitride using reactive ion etching. Successful deposition of UNCD on the substrate with a novel process was confirmed with Raman spectroscopy, X-ray photoelectron spectroscopy, cross-section scanning electron microscopy (SEM) and transmission electron microscopy. Both sample types exhibited uniform geometry and maintained a clear hexagonal pore arrangement. Cellular attachment of SK-N-SH neuroblastoma endothelial cells was examined using confocal microscopy and SEM. Attachment of SK-N-SH cells onto UNCD membranes on both porous regions and solid surfaces was shown, indicating the potential use of UNCD membranes in biomedical applications such as biosensors and tissue engineering scaffolds.

“…Generally speaking, this type of self-assembly is similar in its underlying physical phenomena to ordering of semiconductor islands on 2D surfaces (Eaglesham and Cerullo, 1990), arrays of nickel aluminide precipitates in 3D Ni-base superalloys (Khachaturyan, 1983), and 3D semiconductor island arrays in multilayer systems (Springholz et al, 1998). Also, the ease of making these patterned substrates and the fact that the process can be scaled up to cover large surfaces make them useful master patterns for nanoimprinting to polydimethylsiloxane polymer (Zimmerman et al, 2010), which can be used directly for cell attachment and proliferation studies (Parikh et al, 2012).…”
