Abstract: Nanoparticles (NPs) are an effective way to treat diseases in the modern medicine. NPs can be used as a potent carrier for various drugs such as antibiotics, antivirals and anticancer. Hyaluronic acid-based nanoparticles (HA-NPs) are attracting extensive interest as a drug delivery system in treating cancer due to its excellent biocompatibility and biodegradability. Hyaluronic acid (HA) is a natural biopolymer which have versatile applications. In this study, we constructed molecular models of acetylated HA-NPs (AcHA-NPs) and performed molecular dynamics simulations to provide insight into a molecular assembly of HA-NPs in polar protic and aprotic solvents. Radius of gyration of AcHA-NPs extracted from MD data carried out in DMSO- aqueous mixtures shows a concentration-dependent effect of DMSO on AcHA-NPs assembly. Hydrogen bond and radial distribution function analysis describe how the nanoparticle assembly is maintained in the presence of polar aprotic solvent.
