Abstract Rapid hemostasis is crucial to saving the lives of traumatic patients in emergency medical treatment. To improve the hemostatic performance of the gelatin microspheres (GMs) in vivo and in vitro, in the study, porous gelatin microspheres (PGMs) were prepared through water-in-oil emulsion method combined with vacuum freeze-drying after cross-linking with glutaraldehyde and prefreeze in liquid nitrogen. Owing to the porous structure and rough surface, the obtained PGMs were effective to i...

Self-healing hydrogels as wound dressings still face challenges in infection prevention, especially in the dressing of mass wounds, due to their inflexibility and the slow formation of the protective film on the wound. Therefore, designing a spray-filming (rapid-forming) hydrogel that can serve as a bacterial barrier is of particular significance in the development of wound dressings. Here, a self-healing hydrogel based on adipic acid dihydrazide-modified gelatin (Gel-ADH) and monoaldehyde-modif...

: Background and methods: A Cu-doped composite scaffold of nano calcium-deficient hydroxyapatite (n-CDHA)/multi(amino acid) copolymer (MAC) was prepared. The structure, porosity, morphology and compressive strength of the scaffolds were characterized, the in vitro degradability in phosphate-buffered solution (PBS) and cell responses to the scaffolds were investigated, and in vivo stimulation of bone formation were analyzed. Results: The scaffolds showed the compressive strength of approximately ...

AbstractThe aim of this study was to evaluate the thermal properties and in vivo interface performance of poly(amino acid) (PAA) and a composite containing PAA, hydroxyapatite (HA), and calcium sulfate (CS), with respect to their suitability for skull repair. Biocompatibility was evaluated by implantation of materials into muscles of rabbits for eight weeks. Skull repair was assessed by implanting PAA, the compact PAA/HA/CS composite (c-PAA/HA/CS), and a one-side-porous PAA/HA/CS composite (p-PA...

AbstractThe novel Ca-zeolite/poly(amino acid) (CaY/PAA) composites for bone substitute applications with hemostatic activity were prepared using the in situ melting polymerization method. In this study, Ca-zeolite (CaY) loaded with Ca2+ was obtained from Y-type zeolite (NaY) by ion-exchange method. The properties of the CaY/PAA composites and PAA, including composition, structure, compressive strength, in vitro degradability in phosphate-buffered solution (PBS), bioactivity, cytocompatibility an...

AbstractOwing to the good degradability and biocompatibility of polyphosphoesters (PPEs), the aim of the current study was to investigate a novel degradable composite of nano-hydroxyapatite/poly(amino acid) (n-HA/PAA) with cyclophosphate (CPE) via in situ melting polymerization to improve the degradation of n-HA/PAA. The structure of each composite was characterized via Fourier transform infrared spectroscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. The degradation properties we...
