An Update on Antimicrobial Peptides (AMPs) and Their Delivery Strategies for Wound Infections.Bacterial infections occur when wound healing fails to reach the final stage of healing, which is usually hindered by the presence of different pathogens.  In this review, we focus on antimicrobial peptides (AMPs), especially those with a high potential of efficacy against multidrug-resistant and biofilm-forming bacteria and fungi present in wound infections.  Currently, different AMPs undergo preclinical and clinical phase to combat infection-related diseases. 
AMPs
AMP dendrimers (AMPDs) have been mentioned as potent microbial agents.

New technologies such as Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR)-associated protein (CRISPR-Cas) are taken into consideration as potential future tools for AMP delivery in skin therapy.
