Polyelectrolyte Multilayer Capsule: a Review

Aligned and random nanofibrous nanocomposite scaffolds for bone tissue engineering

Aligned and random nanocomposite nanofibrous scaffolds were electrospun from polycaprolactone (PCL), poly (vinyl alcohol) (PVA) and hydroxyapatite nanoparticles (nHA). The morphology and mechanical characteristics of the nanofibers were evaluated using scanning electron microscopy and tensile testing, respectively. Scanning electron microscopy revealed fibers with an average diameter of 123 ± 3...

Nanostructured natural-based polyelectrolyte multilayers to agglomerate chitosan particles into scaffolds for tissue engineering.

The layer-by-layer (LbL) deposition technique is a self-assembly process that allows the coating of material's surface with nanostructured layers of polyelectrolytes, allowing to control several surface properties. This technique presents some advantages when compared with other thin film assembly techniques, like having the possibility to coat surfaces with complex geometries in mild condition...

Multilayer micromolding of degradable polymer tissue engineering scaffolds

Precise surface geometrical morphologies have been shown to improve cellular proliferation, adhesion, and functionality. It has been found that cells respond strongly to feature dimensions a fraction of their size. In this paper, soft lithography techniques were applied to microfabricate polydimethylsiloxane molds with precisely controlled micro-scale patterns. Three-dimensional polycaprolacton...

Collagen–based scaffolds for skin tissue engineering

The aim of this study was to obtain four collagen based porous scaffolds and to assess their in vitro biocompatibility and biodegradability in order to use them for skin tissue engineering. We have prepared four variants of collagen-based biodegradable sponges by liophilization of type I collagen solution and three variants of collagen-agarose mixture in different ratios 2:1 (A), 1:1 (B) and 1:...
