Abstract
Developing a multifunctional biomaterial for bone filling and local antibiotic therapy is a complex challenge for bone tissue engineering. Hybrid nanocomposites of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBHV) with nanohydroxyapatite (nHA), fullerene (C60), and vancomycin (VC) were produced by injection. Fullerene was successfully impregnated with VC, as seen in FTIR. The crystallinity degree of PHBHV was slightly reduced in the presence of C60 and VC (64.3 versus 60.8 %), due to the plasticizing effect of these particles. It also resulted in a decrease in the glass transition temperature (Tg), observed by differential scanning calorimetry (DSC). Dense PHBHV/nHA/C60/VC had a flexural elastic modulus 29 % higher than PHBHV, as a result of the good interface between PHBHV, C60, and nHA - particles of high elastic modulus. Dense disks released 25.03 ± 4.27 % of VC for 14 days, which demonstrated its potential to be an alternative treatment to bone infections. Porous scaffolds of PHBHV/nHA/C60/VC were 3D printed with a porosity of 50 % and porous size of 467 ± 70 μm, and had compression elastic modulus of 0.022 GPa, being a promising material to trabecular bone replacement. The plasticizing effect of C60 improved the printability of the material. The hybrid nanocomposite was non-cytotoxic and showed good ability in adhering macrophage cells.

Int J Biol Macromol 2023; 226:1041-1053. [PMID: 36435460 DOI: 10.1016/j.ijbiomac.2022.11.221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2022] [Revised: 11/18/2022] [Accepted: 11/21/2022] [Indexed: 11/27/2022]
Abstract
Injection-molded nanocomposites of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBHV) with 6 % of 3-hydroxyvalerate (HV) and amino-nanodiamonds (nD-A) were produced and characterized to investigate the effect of functionalized nanodiamonds on mechanical and biological behavior to bone replacement application. To prepare mixtures of PHBHV and nD-A in different concentrations, nD-A was dispersed in chloroform by sonication with 40 % of amplitude. Three specimens were characterized by infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), X-ray diffraction (DRX), differential scanning calorimetry (DSC), 3-point flexural tests, dynamic mechanical analysis (DMA), and scanning electron microscopy (SEM). FTIR and TGA evidenced the existence of interactions between the nD-A and PHBHV. The crystallinity degree of PHBHV slightly reduced (~9 %) in nanocomposites and the morphology of the crystals changed. Nanocomposites achieved satisfactory dispersion and distribution of nD-A for low concentrations. Elastic modulus (E) increased from 1.96 ± 0.20 (PHBHV) to 2.59 ± 0.19 GPa (PHBHV/1.0%nD-A) (30 %). Despite the relatively limited dispersion, PHBHV/2.0 % nD-A had the best combination of E, strength, and maximum deformation. It had the highest glass transition temperature (43.1 vs 40.3 °C of PHBHV) and the best adhesion coefficient and reinforcement effectiveness. PHBHV-nD-A did not induce toxicity in 7 days and allowed cell fixation and expansion. These bionanocomposites should be considered for supplementary studies for bone tissue engineering.
