Biointerphases emphasizes quantitative characterization of biomaterials and biological interfaces. As an interdisciplinary journal, a strong foundation of chemistry, physics, biology, engineering, theory, and/or modelling is incorporated into originated articles, reviews, and opinionated essays. In addition to regular submissions, the journal regularly features In Focus sections, targeted on specific topics and edited by experts in the field. Biointerphases is an international journal with excellence in scientific peer-review. Biointerphases is indexed in PubMed and the Science Citation Index (Clarivate Analytics). Accepted papers appear online immediately after proof processing and are uploaded to key citation sources daily. The journal is based on a mixed subscription and open-access model: Typically, authors can publish without any page charges but if the authors wish to publish open access, they can do so for a modest fee.Topics include:bio-surface modificationnano-bio interfaceprotein-surface interactionscell-surface interactionsin vivo and in vitro systemsbiofilms / biofoulingbiosensors / biodiagnosticsbio on a chipcoatingsinterface spectroscopybiotribology / biorheologymolecular recognitionambient diagnostic methodsinterface modellingadhesion phenomena.
