Abstract

Polyhydroxyalkanoates (PHAs), recognized as a medical biomaterial, have been proven to promote cell proliferation and tissue repair. PHA has a variety of forms: PHB, PHV, PHHx, and PHBHHx, etc. In this study, PHBHHx was selected as the precursor to fabricate biopolyester films. Specifically, a novel type of biopolyester film was generated through an ammonolysis cross-linking reaction in conjunction with polyamidoamine dendrimer G2.0 (PAMAM). The properties of the resultant biopolyester films were comprehensively evaluated, encompassing surface characteristics, amino group content, and water contact angle. The drug-loading properties and compatibility with osteoblasts of the biopolyester films were also determined. The findings revealed that following aminolysis, the biopolyester film surface exhibited enhanced roughness and an enlarged surface area. Moreover, as the aminolysis duration extended, the hydrophilicity and drug-loading efficiency were significantly augmented. Post-aminolysis, the PHBHHx membrane exhibited a more favorable environment for the adhesion and proliferation of osteoblasts. Overall, the biopolyester film developed in this study provides novel insights and materials for tissue engineering, especially bone tissue repair.

期刊介绍： Molecules (ISSN 1420-3049, CODEN: MOLEFW) is an open access journal of synthetic organic chemistry and natural product chemistry. All articles are peer-reviewed and published continously upon acceptance. Molecules is published by MDPI, Basel, Switzerland. Our aim is to encourage chemists to publish as much as possible their experimental detail, particularly synthetic procedures and characterization information. There is no restriction on the length of the experimental section. In addition, availability of compound samples is published and considered as important information. Authors are encouraged to register or deposit their chemical samples through the non-profit international organization Molecular Diversity Preservation International (MDPI). Molecules has been launched in 1996 to preserve and exploit molecular diversity of both, chemical information and chemical substances.
