Biointerphases is an interdisciplinary, peer-reviewed, open access journal featuring all aspects of quantitative soft matter interfaces:chemistry, physics, engineering, theory and modeling.It publishes reviews,opinionatedessays andoriginalarticles, and makes them accessible without cost to the biomaterials and biointerface community worldwide instantaneously after acceptance, which is typically less than 45 days after submission. Modest publication fees are charged to authors.Topics include interface spectroscopy, in vivo and in vitro mechanisms, interface modeling, adhesion phenomena, protein-surface interactions, biomembranes on a chip, cell-surface interactions, biosensors / biodiagnostics, bio-surface modification, the nano-bio interface, biotribology / biorheology, molecular recognition, cell patterning for function, polyelectrolyte surfaces, and ambient diagnostic methods.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 indexed in PubMed and Thomson Reuters and Elsevier databases.Issues are published quarterly (March/June/September/December).A yearly printed volume is available. Impact Factor: 2.480 Biointerphases is indexed and included in: MEDLINE, the largest component of PubMed; Thomson Reuters products Science Citation Index Expanded, Materials Science Citation Index, Biochemistry & Biophysics Citation Index, Biological Abstracts, and BIOSIS Previews; Elsevier's bibliographic database - SCOPUS and EMBASE.
