Although poly(L-lactide) (PLLA) based porous scaffolds have been widely fabricated through 3D printing, their poor mechanical properties and osteogenic activity still do not meet the needs of bone tissue repair. Herein, chitin whiskers (CHWs), owning outstanding mechanical properties, excellent cell affinity and osteogenic activity, etc. were designed to introduce into PLLA matrix. Moreover, a trisolvent system, including dichloromethane (DCM), 2-butoxyethanlol (2-Bu) and dibutyl phthalate (DBP)...

Abstract The liquid crystalline and rheological properties of chitin whiskers (CHWs) are significant for their application in fabrication of highly ordered composite materials and optical components. The aim of this work was to elucidate the influence of chemical structure and chargeability (zeta potential, electropositivity, electronegativity or zwitterionic character) on the liquid crystalline and rheological properties of CHWs. Firstly, CHWs with different chemical structure, including positi...

Abstract We present here a porous poly (L-lactide)/chitosan (PLLA/CS) composite scaffold with micro/nano-fiber hierarchical structure that was innovatively fabricated by combining 3D printing and thermally induced phase separation technology. Moreover, bioactive quercetin (Qu) was chosen to further functionalize the PLLA/CS scaffold with polydopamine (PDA) layer. The final results showed that the hydrophilicity and mechanical properties of the resulting PLLA/CS-D/Qu scaffold were obviously super...

: A method to mediate biomineralization of electrospinning poly(L-lactide) (PLLA) fibrous membrane assisted by polydopamine (PDA) coating was developed to obtain enhanced osteoconductive activity. The biomineralization mechanism, surface composition, morphology and hydrophilicity of the original and modified PLLA fibrous membranes were characterized. Results revealed that the PDA coating effectively accelerated the formation of hydroxyapatite (HA) on PLLA fibrous membrane and resulted a great in...

Abstract Designing reasonably priced bioactive organic-inorganic hybrid materials featuring osteogenic activity has received a significant interest in the bone tissue engineering field. In this study, eggshell membrane (ESM), which consists mostly of proteins exhibiting fibrous network structure, was utilised innovatively as a template to prepare eggshell membrane/hydroxyapatite (ESM-HA) composites using a versatile biomimetic mineralisation technique. In addition, the surface morphology and com...

Abstract In order to better utilize and combine the advantages of poly( d , l -lactide) (PDLLA) matrix and natural polysaccharide chitin whiskers (CHWs), needle-like CHWs with chiral nematic liquid crystal characteristics and remarkable moduli were chosen to surface modify PDLLA film. By a vertical coating method, a stable and well-ordered CHWs coating was formed on the surface of the PDLLA film through a polydopamine (PDA) interlayer. The high stability of the well-ordered CHWs coating on the s...

Quercetin (Qu), a bioflavonoid, has been reported to positively affect bone metabolism. For the first time, Qu with different concentrations was utilized to functionalize 3D-printed poly(l-lactide) (PLLA) scaffold with the aid of a polydopamine (PDA) layer through a convenient and effective way in this study. Results revealed that the coexistence of PDA and Qu can capacitate the 3D-printed PLLA scaffold to possess rougher surface, as well as better hydrophilicity and compressive properties. The ...
