The synthesized ZnO/MMT photocatalyst was applied to the photodegradation process of methylene blue (MB) and methyl orange (MO) dyes.

The highest percentage of degradation occurred at pH 5 with a photocatalyst mass of 0.2 g for MB and MO dyes, while the irradiation time was 150 min for MB and 180 min for MO, with the percentage of degradation of 99.35 ± 0.22 % and 91.17 ± 1.79 %, respectively. Based on the effectiveness test, the ZnO/MMT photocatalyst showed extraordinary performance with an efficiency up to four cycles against MB and three cycles against MO.

This study employs Density Functional Theory (DFT) and Molecular Dynamics (MD) simulations to investigate the adsorption behavior of Remdesivir and Ivermectin on silver nanoparticles (AgNPs). DFT calculations reveal that Remdesivir exhibits a stronger adsorption affinity (−2.16 eV) and higher charge transfer (0.473 e) compared to Ivermectin (−2.03 eV, 0.415 e), suggesting enhanced electronic interactions with Ag(111). The electrostatic potential (ESP) maps and HOMO-LUMO analysis further confirm Remdesivir's superior binding characteristics. MD simulations support these findings, showing higher RDF peak intensity and lower interaction energy (−2700 kJ/mol for Remdesivir vs. −1600 kJ/mol for Ivermectin), indicating stronger adsorption. The RMSD analysis, conducted after 5 ns of equilibrium, reveals that Remdesivir exhibits greater structural flexibility (∼0.6 nm), while Ivermectin remains more rigidly adsorbed (∼0.5 nm). These results suggest that Remdesivir-coated AgNPs offer enhanced stability, while Ivermectin may allow for controlled drug release. By integrating DFT and MD approaches, this study provides a theoretical framework for optimizing AgNP-based drug delivery systems.

This work discusses the prospects of integrating nanoparticles and additive production techniques to improve medical implants' performance and therapeutic potency.

In orthopedic and dental applications especially, bioactive nanoparticles such as hydroxyapatite and bioactive glass have been promising in enhancing tissue regeneration and osseointegration. Also, antimicrobial nanoparticles such as zinc and silver provide easy ways to hinder infections, a general problem with conventional implants. Also addressed in this paper is how nanoparticles can enable patient-specific implants to react dynamically to the body's needs, such as delivering drug therapy or responding to environmental stimuli. Challenges are there that need to be met, i.e., achieving scalable manufacturing procedures, being sure of biocompatibility, and maintaining long-term implant durability implants with nanoparticles inserted into them despite having many such developments already. Lately, emphasis has been placed on further development, e.g., combining nanoparticles with implant systems via 3D printing processes like FDM, SLA, and SLS. The study also discusses the regulatory environment and safety issues related to such new technology. Integrating functional nanoparticles into the 3D-printed biodegradable implants is a promising path towards developing tissue engineering, regenerative therapy, and personalized medicine.
