主 题:Hydroxyapatite Graphene Large size Silicon nitride nanowires Bone tissue engineering
摘 要:Mimicking the structure of natural bone collagen fibers/hydroxyapatite(HA)to synthesize large size of HA for accelerated bone repair remains a ***,silicon nitride nanowires(SN)-graphene(GE)was designed by the chemical vapor deposition,forming SN-GE(SG)similar to collagen ***,the large size HA was assembled onto SG by pulsed electrochemical deposition,the SG/HA(SGH)mimics the collagen fibers/HA structure of *** introduction of SG induces HA to large size grow in the form of *** can be grown on a large size inextricably with the existence of GE modified *** the one hand,the upright GE sheets effectively increases the surface roughness which enhances the nucleation site of *** the other hand,the C■O provides chemical bonding and induces HA *** with SN/HA(SH),the porosity of SGH decreased by 71%.The average diameter of the SGH is(9.76±0.25)*** with SH,the diameter of SGH is 22 times larger than the diameter of *** that SG induces large size growth of *** work can provide a general strategy for the efficient preparation of biological scaffolds with large size HA that can be used in bone tissue engineering.
