Abstract
Biofilm-biomaterial interfaces have an important role in biofilm development and pose a critical challenge in healthcare, contributing to device failures and chronic infections that affect patient outcomes and healthcare economics. This review explores the complex dynamics of these interfaces, from initial protein adsorption through mature biofilm development, highlighting how bacteria and materials are involved in bidirectional interactions that determine both infection progression and material degradation. It also examines different advanced analytical methods for characterizing these dynamic biofilm-biomaterial interactions, with particular emphasis on the recent developments in electrochemical techniques (ion-selective electrodes, electrochemical impedance spectroscopy, and scanning electrochemical microscopy) that enable real-time monitoring of critical parameters such as pH, oxygen gradients, and metabolic activities, providing unique insights into biofilm heterogeneity and localized chemical changes. In addition, the review explores future developments in sensor technology and standardized protocols needed to accelerate biomaterial innovation, potentially transforming our approach to implant-associated infections through responsive surfaces that adapt to microbial challenges.
期刊介绍:
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 modification
nano-bio interface
protein-surface interactions
cell-surface interactions
in vivo and in vitro systems
biofilms / biofouling
biosensors / biodiagnostics
bio on a chip
coatings
interface spectroscopy
biotribology / biorheology
molecular recognition
ambient diagnostic methods
interface modelling
adhesion phenomena.
