Special Issue Information

Dear Colleagues,

Nanostructured materials are a class of materials whose constituting building units have sizes ranging from 1 to 100 nm in one, two, or three dimensions. Over the past several decades, nanostructured materials have drawn increasing attention worldwide, owing to their unique and excellent properties. The high surface-to-volume ratio, ability for surface functionalization, and superior properties of nanostructured materials provide promising applications in various fields including nanomedicine. As a result, nanostructured materials have become a popular and rapidly evolving research field and have demonstrated promising potential in solving various biomedical problems that cannot be addressed by traditional materials. Various types of nanostructured materials—including quantum dots, nanoparticles, nanospheres, nanorods, nanowires, nanotubes, nanosheets, mesoporous materials, and nanocomposites—have been synthesized and investigated for applications in various biomedical fields, such as drug delivery, bone defect repair, orthopedic surgery, tooth repair, skin wound healing, tissue engineering, regenerative medicine, anti-tumor therapy, biosensing, bioimaging, diagnosis, and therapy.

This Special Issue on “Nanostructured Materials: Synthesis, Functionalization and Applications in Biomedicine—2nd Edition” aims to gather original interdisciplinary research on the recent progress in nanostructured materials for biomedical applications. This Special Issue focuses on all aspects of research regarding the design strategy, synthesis, characterization, functionalization, and biomedical applications of nanostructured materials. The first edition of the Special Issue was completed after the successful collection of more than 10 papers. Please refer to the following website for the first edition of the Special Issue: https://www.mdpi.com/journal/molecules/special_issues/Nanostructured_Materials. It is our great pleasure to invite researchers in the relevant fields to contribute original research manuscripts, including full research papers, short communications, and reviews, to the 2nd edition of this Special Issue.

Zinc oxide (ZnO) and iron oxide (IO) nanoparticles have been identified as promising candidates for biomedical applications, based on their unique physicochemical properties. The association of these nanoparticles in a single system creates a bimodal entity, allowing the excellent luminescent properties of ZnO quantum dots to be combined with the contrast agent of IO for magnetic resonance imaging (MRI). The present study focuses on the luminescent and MRI properties of a new poly(lactic-co-glycolic acid) (PLGA) nanocarrier system formulation containing ZnO NPs and IO NPs in different nominal ratios. Microscopic analysis (TEM and SEM) reveals a circular morphology with IO and ZnO NPs. The average diameter of the particles was determined to be 220 nm, as measured by DLS. The luminescence results indicate that the PLGA system shows strong emission in the visible range, and the MRI analysis shows a high r2 relaxivity of 171 mM−1 s−1 at 7T. The optimized formulation, exhibiting a molar ratio of Fe:Zn ranging from 1:10 to 1:13 (mol:mol), demonstrates superior fluorescence and MRI performance, underscoring the significance of nanoparticle composition in bimodal imaging applications. The systems evaluated demonstrate no toxicity in the THP-1 cells for doses of up to 128 µg mL−1, with efficient labeling after 4 h of incubation, yielding images of strong luminescence and T2 contrast. The PLGA:ZnO:IO system demonstrates considerable potential as a bimodal platform for diagnostic imaging. Full article

Sustainable and eco-friendly synthesis methods for nanoparticles are crucial for advancing green nanotechnology. This study presents the biogenic synthesis of zinc oxide (ZnO) and magnesium oxide (MgO) nanoparticles using ovalbumin, an abundant and non-toxic protein from egg white. The synthesis process was optimized by varying metal ion concentrations to control particle size and morphology. Characterization using ATR-FTIR, XRD, SEM, and UV-VIS confirmed the successful formation of uniform, well-crystallized nanoparticles with sizes ranging from 7.9 to 13.5 nm. ZnO nanoparticles exhibited superior antimicrobial efficacy against Escherichia coli and Enterococcus faecalis, while MgO nanoparticles showed enhanced potential environmental remediation. These findings highlight ovalbumin as a versatile agent for the green synthesis of ZnO and MgO nanomaterials, with promising applications in the medical, environmental, and optoelectronic fields. The results indicate that this biogenic method can serve as a sustainable proposal to produce nanostructured materials with diverse applications in the medical and environmental fields, such as eliminating pathogenic bacteria and purifying contaminated environments. Overall, this study significantly contributes to the development of sustainable nanomaterials and opens up new perspectives on the use of ovalbumin protein in the synthesis of multifunctional nanostructured materials.
