Aminoacid functionalised magnetite nanoparticles Fe 3O 4@AA (AA = Ser, Cys, Pro, Trp) as biocompatible magnetite nanoparticles with potential therapeutic applications. Sci Rep 2024; 14:26228. [PMID: 39482399 PMCID: PMC11528115 DOI: 10.1038/s41598-024-76552-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2024] [Accepted: 10/15/2024] [Indexed: 11/03/2024] Open
Abstract
Magnetic nanoparticles (MNPs) are of great interest for their wide applications in biomedical applications, such as bioimaging, antitumoral therapies, regenerative medicine, and drug delivery. The work aimed to obtain biocompatible magnetite nanoparticles coated with amino acids of the general formula Fe3O4@AA (AA = L-tryptophan, L-serine, L-proline and L-cysteine) for potential therapeutic application in anticancer drug delivery. The obtained materials were characterised using XRD, FTIR, DLS analysis, SEM, thermogravimetry (TG), differential scanning calorimetry (DSC), and UV-vis spectroscopy. The photocatalytic, cytotoxic and antimicrobial activity tests of the obtained materials were carried out. The choice of amino acid determines the properties of the material and its future use, for example, Fe3O4@Cys supports radical production, which may increase the efficiency of catalytic degradation, while tryptophan captures radicals, which may be an advantage in several biomedical applications. Fe3O4@Trp exhibited good antimicrobial activity (MBEC and MIC) against E. coli ATCC 25922, P. aeruginosa ATCC 27853 and C. albicans ATCC 10231 while Fe3O4@Pro exhibited the best results against S. aureus ATCC 25923.

Nanostructured Coatings Based on Graphene Oxide for the Management of Periprosthetic Infections. Int J Mol Sci 2024; 25:2389. [PMID: 38397066 PMCID: PMC10889398 DOI: 10.3390/ijms25042389] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Revised: 02/12/2024] [Accepted: 02/13/2024] [Indexed: 02/25/2024] Open
Abstract
To modulate the bioactivity and boost the therapeutic outcome of implantable metallic devices, biodegradable coatings based on polylactide (PLA) and graphene oxide nanosheets (nGOs) loaded with Zinforo™ (Zin) have been proposed in this study as innovative alternatives for the local management of biofilm-associated periprosthetic infections. Using a modified Hummers protocol, high-purity and ultra-thin nGOs have been obtained, as evidenced by X-ray diffraction (XRD) and transmission electron microscopy (TEM) investigations. The matrix-assisted pulsed laser evaporation (MAPLE) technique has been successfully employed to obtain the PLA-nGO-Zin coatings. The stoichiometric and uniform transfer was revealed by infrared microscopy (IRM) and scanning electron microscopy (SEM) studies. In vitro evaluation, performed on fresh blood samples, has shown the excellent hemocompatibility of PLA-nGO-Zin-coated samples (with a hemolytic index of 1.15%), together with their anti-inflammatory ability. Moreover, the PLA-nGO-Zin coatings significantly inhibited the development of mature bacterial biofilms, inducing important anti-biofilm efficiency in the as-coated samples. The herein-reported results evidence the promising potential of PLA-nGO-Zin coatings to be used for the biocompatible and antimicrobial surface modification of metallic implants.
