In this work, needle-like and micro-spherical agglomerates of nanocrystalline hydroxyapatite (HA) were successfully assembled on the surface of graphene sheets with the aid of dopamine having two roles, as a template and a reductant for graphite oxide during the process of self-polymerization. The crystalline structure and micromorphology of HA can be conveniently regulated by controlling the m...

Aspartic acid is prepared chemically or by the fermentation of carbohydrates. Currently, low molecular weight polyaspartic acids are prepared commercially by heating aspartic acid at high temperatures (>220 C) for several hours in the solid state. In an effort to develop a more rapid, continuous, melt polymerization scheme, aspartic acid was copolymerized with adipic, azelaic, sebacic, and dode...

Nanoparticles possessing multiple functionalities provide synthetic handles for varied surface chemistries, making them useful for a range of applications such as biotargeting and drug delivery. However, the combination of interfering functionalities on the same particle is often challenging. We have employed a synthetic scheme involving chemical protection/deprotection to combine interfering f...

Ultrathin polymer film is deposited on the surfaces of vapor-grown carbon nanofibers by a plasma polymerization using acrylic acid as a monomer. Small angle light scattering is used to investigate the dispersion behavior of the carbon nanofibers suspended in water and provides information on the mechanism by which plasma treatment assists dispersion. Both plasma-treated and untreated nanofibers...

Fully biodegradable and surface-functionalized poly(D,L-lactide) (PLA) nanoparticles have been prepared by a co-precipitation technique. Novel amphiphilic random copolyesters P(CL-co-γXCL) were synthesized by controlled copolymerization of ε-caprolactone and ε-caprolactone substituted in the γ-position by a hydrophilic X group, where X is either a cationic pyridinium (γPyCL) or a non-ionic hydr...

Highlights . We have proposed and patented a method for obtaining fully autologous fibrin without the use of exogenous thrombin, which can be implemented within framework personalized approach in tissue engineering. Such fibrin, addition to lower risk infection inflammation, possesses greater strength resistance degradation, as well better hemocompatibility compared polymerized with is an undou...
