Nanocomposite hydrogels that are reinforced with carbon-based nanomaterials are mechanically tough and electrically conductive, which make them suitable for use in biomedicine, tissue engineering, drug delivery, biosensing, etc. The electrical conductivity property of these hydrogels allows them to mimic the characteristics of nerve, muscle ...
Nanoparticles such as graphene, [6] carbon nanotubes, molybdenum disulfide and tungsten disulfide are being used as reinforcing agents to fabricate mechanically strong biodegradable polymeric nanocomposites for bone tissue engineering applications. The addition of these nanoparticles in the polymer matrix at low concentrations (~0.2 weight ...
A range of polymeric nanocomposites are used for biomedical applications such as tissue engineering, drug delivery, cellular therapies. [29] [30] Due to unique interactions between polymer and nanoparticles, a range of property combinations can be engineered to mimic native tissue structure and properties. A range of natural and synthetic ...
Micro-mass cultures of C3H-10T1/2 cells at varied oxygen tensions stained with Alcian blue. A commonly applied definition of tissue engineering, as stated by Langer [3] and Vacanti, [4] is "an interdisciplinary field that applies the principles of engineering and life sciences toward the development of biological substitutes that restore, maintain, or improve [Biological tissue] function or a ...
Nanotechnology may be used as part of tissue engineering to help reproduce, repair, or reshape damaged tissue using suitable nanomaterial-based scaffolds and growth factors. If successful, tissue engineering if successful may replace conventional treatments like organ transplants or artificial implants.
The basis of bone tissue engineering is that the materials will be resorbed and replaced over time by the body’s own newly regenerated biological tissue. [60] Tissue engineering is not only limited to the bone: a large amount of research is devoted to cartilage, [64] ligament, [65] skeletal muscle, [66] skin, [67] blood vessel, [68] and ...
Nanomaterials can also be used in three-way-catalyst applications, which have the advantage of controlling the emission of nitrogen oxides (NO x), which are precursors to acid rain and smog. [45] In core-shell structure, nanomaterials form shell as the catalyst support to protect the noble metals such as palladium and rhodium. [46]
Nanostructured hollow multilayered tubes can be created by combining layer-by-layer (LbL) and template leaching. Such materials are of particular interest for tissue engineering since they allow the precise control of physical and biochemical cues of implantable devices. The tubes are based on polyelectrolyte multilayer films.
