Special Issue Information

Dear Colleagues,

Nanoparticle assembly is a cutting-edge field within nanotechnology and materials science, focusing on the organization of nanoparticles into larger, structured formations. These assemblies exhibit novel properties and functionalities that are not present in individual nanoparticles, driven by interparticle forces (such as van der Waals interactions, electrostatic forces, and steric effects), chemical bonding, and surface decoration. Characterizing these assemblies through advanced techniques like transmission electron microscopy (TEM), scanning electron microscopy (SEM), and various spectroscopic techniques is crucial for understanding their structure and properties. The significance of research in nanoparticle assembly lies in its wide-ranging applications, from drug delivery and imaging in biomedicine to fabricating electronic devices enhancing the efficiency of photovoltaics and developing advanced materials with superior mechanical, thermal, and electrical properties.

We are pleased to invite you to contribute to this Special Issue with your full papers, reviews, or communications on experimental and theoretical results of nanoparticle assembly.

The aim of this Special Issue is to explore novel assembly techniques, elucidate the mechanisms underlying nanoparticle interactions, demonstrate computational and experimental characterization techniques, and highlight cutting-edge applications and the potential of assembled nanostructures.

I look forward to receiving your contributions.

This study involved the fabrication of poly (vinyl alcohol) (PVA) nanocomposite films using the solution-casting process, which incorporated strontium-coated silver oxide (Sr-Ag2O) nanoparticles generated by a plant-extract assisted method. Various characterization techniques, such as XRD, SEM, TEM, UV, and FTIR, showed the formation and uniform distribution of Sr-Ag2O nanoparticles in the PVA film, which are biocompatible nanocomposite films. The presence of hydroxyl groups leads to appreciable mixing and interaction between the Sr-Ag2O nanoparticles and the PVA polymer. Mechanical and thermal results suggest enhanced tensile strength and increased thermal stability. In addition, the sample of PVA/Sr-Ag2O (1.94/0.06 wt. ratio) nanocomposite film showed decreased hydrophilicity, lower hemolysis, non-toxicity, and appreciable cell migration activity, with nearly 19.95% cell migration compared to the standard drug, and the presence of Sr-Ag2O nanoparticles favored the adhesion and spreading of cells, which triggered the reduction in the gaps. These research findings suggest that PVA/Sr-Ag2O nanocomposite films with good mechanical, antimicrobial, non-toxic, and biocompatible properties could be applied in biological wound-healing applications.
