Summary: This research investigated the impact of magnetic Fe3O4 nanoparticles on nanocomposite films made of shape memory polymers. PLA-PEG blend nanocomposite films were prepared with different ratios of MNP. The films were studied using ATR-IR, TGA, DSC, SEM, and VSM to analyze their thermal stability, morphology, magnetic behavior, and shape memory properties. The antimicrobial activity of the films was also compared. The results showed that MNP increased thermal stability and inhibited microbial growth.

Summary: A new type of magnetic nanomaterial, consisting of Fe3O4 as core and organic polymer as shell, was synthesized using seed emulsion polymerization. This material exhibits improved mechanical strength of the organic polymer and prevents the oxidation and agglomeration of Fe3O4. Solvothermal method was employed to prepare Fe3O4 with desired particle size. The effects of reaction time, solvent amount, pH value, and polyethylene glycol (PEG) on the particle size of Fe3O4 were investigated. The obtained C18-functionalized magnetic nanomaterials were used for preparing the chromatographic column, achieving efficient and selective elution.

Summary: A highly photostable nanoprobe based on conjugated polymer, poly(para-phenylene ethynylene), has been developed. The tumor targeting ligands folate modification allows for easy and selective cellular uptake of these nanoprobes. By grafting extended polyester side chains, the interchain energy transfer between conjugated polymer backbones is minimized, leading to an increase in quantum yield.

Summary: This study showed that the expression of biofilm-associated genes in Candida albicans changed after treatment with magnetic iron oxide nanoparticles (nano-Fe3O4). The biologically synthesized nano-Fe3O4 inhibited the growth and biofilm formation of C. albicans by downregulating the expression of BCR1, ALS1, ALS3, HWP1, and ECE1 genes.

Summary: Thin film coatings with potent antibacterial properties are widely used in medical devices, frequently touched surfaces, and food packaging. However, achieving antibacterial performance under both light and dark conditions remains a challenge. In this study, we successfully prepared AgBr-coated ZnO nanorod thin film architecture using a unique surfactant-mediated solution-phase spin-coating approach. The resulting structures showed dual functionality as antimicrobial agents and photosensitizers, effectively enhancing the visible-light photodisinfection efficacy of ZnO nanorods. The concentration of the surfactant-based precursor solution could be modulated to control the AgBr content. Additionally, components like urea and lactic acid were found to enhance the photocatalytic efficiency of the structures.
