Carbon nanotubes (CNT) possess excellent mechanical properties to play the role as reinforcement for imparting strength and toughness to brittle hydroxyapatite (HA) bioceramic coating. However, lack of processing technique to uniformly distribute multiwalled CNTs in HA coating and limited studies and sparse knowledge evincing toxicity of CNTs has kept researchers in dispute for long. In the cur...
Due to its bioactivity, hydroxyapatite (HAp) is one of the most perspective materials for controlled drug delivery. Biodegradable polymers like chitosan and sodium alginate are used as coating materials for ceramic scaffolds. In this work the application of HAp/sodium alginate or chitosan composite materials which provide controlled lidocaine release is discussed. The polymers and lidocaine hyd...
Alkaline agents are well-known for their disinfection capacities against pathogens even at the presence of organic materials, but the durability of their bactericidal efficacies under field conditions is unknown. Therefore, within the present study, two alkaline agents, namely bioceramic (BCX) derived from chicken feces and food additive grade Ca(OH)2 (FdCa(OH)2) derived from natural lime stone...
Deer antler is a unique example of mammalian long bone because it regenerates annually with an extremely rapid rate of growth. This study describes a low-field NMR technique combined with cryoporimetric calibration for the estimation of pore size distribution in antler bone from spin-spin (T2) relaxation data. Pore sizes determined by the NMR method have been compared with the more traditional ...
Introduction Each year in the United States approximately 500,000 procedures that involve the use of bone substitutes are performed. To address the limitations of materials currently used in orthopaedic tissue engineering, we have developed novel nanocomposite materials that consist of a citric acid-based elastomer, poly(1,8 octanediol citrate) (POC) and bioceramic nanoparticles, βtricalcium ph...
