Management of biofilm-associated infections in diabetic wounds – from bench to bedside
Biofilms are complex bacterial colonies embedded in an extracellular matrix. These pose a major obstacle to wound healing and are noticeable in chronic wounds. It protects the bacteria from the host’s immune system and conventional antibiotic treatments. The biofilm’s protective matrix prevents essential nutrients and oxygen from diffusing into the surrounding healthy tissue. In addition, microbes living in biofilms naturally have increased resistance to antibiotics, which reduces the effectiveness of traditional therapies. As such, biofilms serve as persistent reservoirs of infection, which further disrupts the normal course of wound healing. In this review, the current formulation strategies such as hydrogels, polymeric nanoparticles, and nanofibers that are used in wound healing to counteract biofilms have been comprehensively discussed. The formulations have been meticulously designed and developed to disturb the biofilm matrix, prevent the growth of microorganisms, and increase the potency of antimicrobials and antibiotics. The mechanism of action, advantages and limitations associated with the existing formulation strategies have been reviewed. The formulation strategies that have been translated into clinical applications and patented are also discussed in this paper.
期刊介绍:
Pure and Applied Chemistry is the official monthly Journal of IUPAC, with responsibility for publishing works arising from those international scientific events and projects that are sponsored and undertaken by the Union. The policy is to publish highly topical and credible works at the forefront of all aspects of pure and applied chemistry, and the attendant goal is to promote widespread acceptance of the Journal as an authoritative and indispensable holding in academic and institutional libraries.
