The modification improved the compatibility between MgO/Ag NPs and PBST matrix. The study comprehensively investigated the effects of modified MgO/Ag NPs on the mechanical, antibacterial, and preservation properties of bio-nanocomposite films. The incorporation of NPs substantially improved the mechanical and barrier properties of the PBST matrix. The composite films exhibited the best overall performance when the nanoparticle content is 3 %. In particular, the elongation at break, tensile strength, and water vapor permeability (<em>WVP</em>) were 794.67 %, 32.20 MPa, and 1.53 × 10⁻¹¹ g·m/m²·s·Pa, respectively. Furthermore, the K-PMA-3 composite film exhibited excellent antibacterial properties and food preservation performance. The inhibition rates against <em>Staphylococcus aureus</em> (<em>S. aureus</em>), <em>Escherichia coli</em> (<em>E. coli</em>), and <em>Salmonella paratyphi B</em> (<em>S. paratyphi B</em>) were all over 98 %. After 6 days of preservation experiments, the mass loss of cherry tomatoes wrapped with K-PMA-3 film was only 5.9 %, which was only 45 % of the mass loss of cherry tomatoes wrapped with PMA-3 film. The results showed that the prepared biofilms have a great potential to be used as food packaging films.</div></div>","PeriodicalId":20916,"journal":{"name":"Reactive & Functional Polymers","volume":"206 ","pages":"Article 106112"},"PeriodicalIF":4.5,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142747462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Covering the surface of PLGA nanoparticles (NPs) with a thermoresponsive shell may be the key factor for building drug delivery systems with temporal and spatial control. In this respect, PLGA NPs with a mean size of 212 nm, containing dexamethasone (Dex) (Dex/PLGA NPs) have been produced by the dialysis technique without the use of a surfactant. Then, the nanoparticles were covered with poly(N-isopropylacrylamide-<em>co</em>-4-vinyl pyridine) (PVP) by ionic interactions between the amine groups of the PVP and carboxylic groups of PLGA.

The assembly of PVP on the PLGA NPs was analyzed by monitoring the particle size with temperature, zeta potential, AFM, and TEM analysis. The in vitro drug delivery investigation showed that temperature has significant control over the release rate of Dex from PVP-coated PLGA NPs. The thermosensitive polymer is hydrated at temperatures lower than LCST (20 °C) and forms a gel around the nanoparticles slowing down the release rate of Dex.
