Special Issue Information

Dear Colleagues,

Antimicrobial peptides are a class of small molecules composed of peptides with antimicrobial activity, possessing unique mechanisms against various pathogens, and are considered one of the important directions in future antimicrobial drug research. Traditional methods for screening and designing antimicrobial peptides suffer from issues such as high costs, low efficiency, and time consumption. In contrast, through data-driven machine learning methods, researchers can utilize large-scale biological data for pattern recognition and prediction, thereby accelerating the process of discovering antimicrobial peptides. Additionally, molecular dynamics simulation techniques can simulate the interactions between antimicrobial peptides and target molecules, revealing their structural and functional features at the molecular level and providing crucial insights for designing antimicrobial peptides with enhanced selectivity and efficacy. This Special Issue aims to explore the acceleration of the discovery of novel antimicrobial peptides and their antimicrobial mechanism research using machine learning and molecular dynamics simulation. The goal is to leverage computational biology techniques to expedite the discovery and development of safer and more effective antimicrobial peptide drugs, bringing new hope and possibilities to human health and the field of antimicrobial therapy.

We welcome manuscripts that use computational screening tools to identify the potential activity of novel antimicrobial peptides and confirm them experimentally. We also encourage manuscripts that focus on the development of novel computational screening pipelines or tools and provide supporting data to demonstrate the validity of their approach.

We look forward to receiving your manuscripts and collaborating with you on an impactful Special Issue.

Background: Green synthesized nanoparticles (NPs) have gained increasing popularity in recent times due to their broad spectrum of antimicrobial properties. This study aimed to develop a phytofabrication approach for producing cuprous (Cu2O) and cupric oxide (CuO) NPs using a simple, non-hazardous process and to examine their antimicrobial properties. Methods: The synthesis employed Bidens pilosa plant extract as a natural reducing and stabilizing agent, alongside copper chloride dihydrate as the precursor. The biosynthesized NPs were characterized through various techniques, including X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier-transform infrared (FT-IR) spectroscopy, ultraviolet–visible (UV-Vis) spectroscopy, scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS). Results: XRD analysis confirmed that the synthesized CuO and Cu2O NPs exhibited a high degree of crystallinity, with crystal structures corresponding to monoclinic and face-centered cubic systems. SEM images revealed that the NPs displayed distinct spherical and sponge-like morphologies. EDS analysis further validated the purity of the synthesized CuO NPs. The antimicrobial activity of the CuO and Cu2O NPs was tested against various pathogenic bacterial strains, including Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Bacillus cereus, with the minimum inhibitory concentration (MIC) used to gauge their effectiveness. Conclusions: The results showed that the phytosynthesized NPs had promising antibacterial properties, particularly the Cu2O NPs, which, with a larger crystal size of 68.19 nm, demonstrated significant inhibitory effects across all tested bacterial species. These findings suggest the potential of CuO and Cu2O NPs as effective antimicrobial agents produced via green synthesis. Full article
