--- res: bibo_abstract: - The development of bioresorbable materials for temporary implantation enables progress in medical technology. Iron (Fe)-based degradable materials are biocompatible and exhibit good mechanical properties, but their degradation rate is low. Aside from alloying with Manganese (Mn), the creation of phases with high electrochemical potential such as silver (Ag) phases to cause the anodic dissolution of FeMn is promising. However, to enable residue-free dissolution, the Ag needs to be modified. This concern is addressed, as FeMn modified with a degradable Ag-Calcium-Lanthanum (AgCaLa) alloy is investigated. The electrochemical properties and the degradation behavior are determined via a static immersion test. The local differences in electrochemical potential increase the degradation rate (low pH values), and the formation of gaps around the Ag phases (neutral pH values) demonstrates the benefit of the strategy. Nevertheless, the formation of corrosion-inhibiting layers avoids an increased degradation rate under a neutral pH value. The complete bioresorption of the material is possible since the phases of the degradable AgCaLa alloy dissolve after the FeMn matrix. Cell viability tests reveal biocompatibility, and the antibacterial activity of the degradation supernatant is observed. Thus, FeMn modified with degradable AgCaLa phases is promising as a bioresorbable material if corrosion-inhibiting layers can be diminished.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Jan Tobias foaf_name: Krüger, Jan Tobias foaf_surname: Krüger foaf_workInfoHomepage: http://www.librecat.org/personId=44307 orcid: 0000-0002-0827-9654 - foaf_Person: foaf_givenName: Kay-Peter foaf_name: Hoyer, Kay-Peter foaf_surname: Hoyer foaf_workInfoHomepage: http://www.librecat.org/personId=48411 - foaf_Person: foaf_givenName: Jingyuan foaf_name: Huang, Jingyuan foaf_surname: Huang - foaf_Person: foaf_givenName: Viviane foaf_name: Filor, Viviane foaf_surname: Filor - foaf_Person: foaf_givenName: Rafael Hernan foaf_name: Mateus-Vargas, Rafael Hernan foaf_surname: Mateus-Vargas - foaf_Person: foaf_givenName: Hilke foaf_name: Oltmanns, Hilke foaf_surname: Oltmanns - foaf_Person: foaf_givenName: Jessica foaf_name: Meißner, Jessica foaf_surname: Meißner - foaf_Person: foaf_givenName: Guido foaf_name: Grundmeier, Guido foaf_surname: Grundmeier foaf_workInfoHomepage: http://www.librecat.org/personId=194 - foaf_Person: foaf_givenName: Mirko foaf_name: Schaper, Mirko foaf_surname: Schaper foaf_workInfoHomepage: http://www.librecat.org/personId=43720 bibo_doi: 10.3390/jfb13040185 bibo_issue: '4' bibo_volume: 13 dct_date: 2022^xs_gYear dct_isPartOf: - http://id.crossref.org/issn/2079-4983 dct_language: eng dct_publisher: MDPI AG@ dct_subject: - Biomedical Engineering - Biomaterials dct_title: FeMn with Phases of a Degradable Ag Alloy for Residue-Free and Adapted Bioresorbability@ ...
