Abstract Fungal infections caused by Candida spp.represent an emerging problem during treatment of immunocompromised patients and those hospitalized fish print mens pink polo shirt with serious principal diseases.The ever-growing number of fungal strains exhibiting drug resistance necessitates the development of novel antimicrobial therapies including those based on membrane-permeabilizing agents and nanomaterials as drug carriers.

In this study, the fungicidal activities of LL-37 peptide, ceragenin CSA-13 and its magnetic derivatives (MNP@LL-37, MNP@CSA-13) against laboratory and clinical strains of C.albicans, C.glabrata and C.

tropicalis were evaluated.These experiments confirm the high anti-fungal activity of these well-characterized agents mediated by their interaction with the fungal membrane and demonstrate elevated activity following immobilization of LL-37 and CSA-13 on the surface of magnetic nanoparticles (MNPs).Furthermore, MNP-based nanosystems are resistant to inhibitory factors present in body fluids and effectively inhibit formation of fungal biofilm.

Simultaneously, synthesized nanostructures maintain immunomodulatory properties, described previously for free LL-37 peptide and CSA-13 5th marine division patch substrate and they do not interfere with the proliferation and viability of osteoblasts, confirming their high biocompatibility.
