Preparation of foam-like carbon nanotubes/hydroxyapatite composite scaffolds with superparamagnetic properties

Albumin adsorption study onto hydroxyapatite-multiwall carbon nanotube based composites

“…Just like in the research of Venkatesan et al, a uniform distribution of HAP particles and of fMWCNT in the polymer matrix was observed, which may be due to the electrically charged nature of the chitosan network [45]. The small pores distributed on the big pore walls improve the interconnectivity of porous scaffolds, which is more important for cell attachment, for new bone formation and for osteoconduction than the size of the pores [46]. When comparing the SEM images of the composites with and without silica, no significant differences could be observed.…”

Biodegradable Chitosan/Multiwalled Carbon Nanotube Composite for Bone Tissue Engineering

“…Several efforts have investigated the use of biodegradable polymers, for instance, hydroxyapatite/poly (caprolactone) [3]. Several methods have been used to produce porous scaffolds, such as foaming, gel casting, polymer replication/impregnating, solvent casting, particulate leaching and phase separation [5], computerized design and manufacture of three dimensional (3D) architectures [4].…”

“…On the other hand, carbon nanotubes (CNTs) have been used in tissue engineering as a candidate for bone tissue engineering scaffolds due to its excellent mechanical properties, large surface specific areas and high electronic conductivity [8,13] as well as magnetic properties [5]. It is also considered that is a suitable material for tissue engineering [1].…”

Synthesis of carbon nanotubes loaded hydroxyapatite: Potential for controlled drug release from bone implants

“…They freezed the polymeric suspension of HA and CNTs and ejected it from a syringe at a constant speed, achieving the formation of well-aligned micro-channel structures. Lu et al [14], on the other hand, produced foam like chitosan/HA scaffolds in which CNTs were grown in situ by a chemical vapour deposition method; they obtained highly crystalline nanotubes in Ca deficient HA matrices.…”
