Special Issue Information

Dear Colleagues,

Nanostructured materials are materials containing an internal or surface structure in the nanometer length scale on which their properties depend. Organic, inorganic, and hybrid nanostructures find broad application across several areas of pharmaceutics and biomedicine. In particular, medicinal chemistry, drug delivery, and tissue engineering have benefited from the progress in such technologies. Considerable advances have characterized the recent application of nanostructured materials in medicine, from diagnostic biosensors to scaffolds for tissue engineering, without forgetting the high relevance in catalysis and biocatalysis applied to biology and chemical synthesis.

This Special Issue aims at the most recent advances in nanostructured material across chemistry and biology, including manufacturing and potential toxicity issues. Particular importance will be given to applications in medicinal chemistry and flow chemistry, targeted and local drug nanocarriers, nanostructured matrices for controlled release, biosensors, and functional nanomaterials and their biological relevance.

Accepted papers are published in the joint Special Issue in ijms or Pharmaceutics.(https://0-www-mdpi-com.brum.beds.ac.uk/journal/pharmaceutics/special_issues/pharm

Hybrid nanostructures can be developed with inorganic nanoparticles (NPs) such as zinc oxide (ZnO) and natural antibacterials. ZnO NPs can also exert antibacterial effects, and we used them here to examine their dual action in combination with a natural antibacterial agent, protocatechuic acid (PCA). To produce hybrid nanoformulations, we functionalized ZnO NPs with four types of silane organic molecules and successfully linked them to PCA. Physicochemical assessment confirmed PCA content up to ~18% in hybrid nanoformulations, with a PCA entrapment efficiency of ~72%, indicating successful connection. We then investigated the in vitro release kinetics and antibacterial effects of the hybrid against Staphylococcus aureus. PCA release from hybrid nanoformulations varied with silane surface modification. Within 98 h, only 8% of the total encapsulated PCA was released, suggesting sustained long-term release. We used nanoformulation solutions collected at days 3, 5, and 7 by disc diffusion or log reduction to evaluate their antibacterial effect against S. aureus. The hybrid nanoformulation showed efficient antibacterial and bactericidal effects that also depended on the surface modification and at a lower minimum inhibition concentration compared with the separate components. A hybrid nanoformulation of the PCA prodrug and ZnO NPs offers effective sustained-release inhibition of S. aureus growth. Full article
