Bioadhesives with Antimicrobial Properties

Abstract

Bioadhesives with antimicrobial properties enable easier and safer treatment of wounds as compared to the traditional methods such as suturing and stapling. Composed of natural or synthetic polymers, these bioadhesives seal wounds and facilitate healing while preventing infections through the activity of locally released antimicrobial drugs, nanocomponents, or inherently antimicrobial polers. Although many different materials and strategies are employed to develop antimicrobial bioadhesives, the design of these biomaterials necessitates a prudent approach as achieving all the required properties including optimal adhesive and cohesive properties, biocompatibility, and antimicrobial activity can be challenging. Designing antimicrobial bioadhesives with tunable physical, chemical, and biological properties will shed light on the path for future advancement of bioadhesives with antimicrobial properties. In this review, the requirements and commonly used strategies for developing bioadhesives with antimicrobial properties are discussed. In particular, different methods for their synthesis and their experimental and clinical applications on a variety of organs are reviewed. Advances in the design of bioadhesives with antimicrobial properties will pave the way for a better management of wounds to increase positive clinical outcomes. The research on bioadhesives is gaining new heights with the incorporation of innovative antimicrobial activity mechanisms. Strategies to achieve antimicrobial activity without compromise from biocompatibility, adhesion and cohesion are being devised. Unique approaches in the application of these bioadhesives and methods to reveal their elusive properties are diversifying. Bioadhesives are coming one step closer to replace many traditional surgical devices in the clinic.image
