“…Also, those can include a delivery vehicle or a delivery system for drugs and therapeutic agents, given the numerous nanosystems which have found application in diagnostics. Rivera and collaborators [ 11 ] have defined nanopharmaceuticals as: pharmaceuticals engineered on the nanoscale, i.e., pharmaceuticals where the nanomaterial plays the pivotal therapeutic role or adds additional functionality to the previous compound .…”

This study provides a brief discussion of the major nanopharmaceuticals formulations as well as the impact of nanotechnology on the future of pharmaceuticals. Effective and eco-friendly strategies of biofabrication are also highlighted. Modern approaches to designing pharmaceutical nanoformulations (e.g., 3D printing, Phyto-Nanotechnology, Biomimetics/Bioinspiration, etc.) are outlined. This paper discusses the need to use natural resources for the “green” design of new nanoformulations with therapeutic efficiency. Nanopharmaceuticals research is still in its early stages, and the preparation of nanomaterials must be carefully considered. Therefore, safety and long-term effects of pharmaceutical nanoformulations must not be overlooked. The testing of nanopharmaceuticals represents an essential point in their further applications. Vegetal scaffolds obtained by decellularizing plant leaves represent a valuable, bioinspired model for nanopharmaceutical testing that avoids using animals. Nanoformulations are critical in various fields, especially in pharmacy, medicine, agriculture, and material science, due to their unique properties and advantages over conventional formulations that allows improved solubility, bioavailability, targeted drug delivery, controlled release, and reduced toxicity. Nanopharmaceuticals have transitioned from experimental stages to being a vital component of clinical practice, significantly improving outcomes in medical fields for cancer treatment, infectious diseases, neurological disorders, personalized medicine, and advanced diagnostics. Here are the key points highlighting their importance. The significant challenges, opportunities, and future directions are mentioned in the final section.

In the present work, nanoparticles of Al2O3, Cu-Al2O3, and Ni-Al2O3 were prepared using Hibiscus rosa-sinensis plant leaf extract through co-precipitation method. The prepared nanomaterials were characterized through TGA, EDX, SEM, UV-Vis, XRD, and FTIR instruments. The electrochemical behavior of Al2O3, Cu-Al2O3, and Ni-Al2O3 has been studied in DMF solution in the potential ranges from −1.5 to 1.5 V. The nanoparticles are thermally stable, according to the TGA, and the XRD patterns revealed that all the Al2O3, Cu-Al2O3, and Ni-Al2O3 particles were crystalline, with the mean sizes of 12.44, 34.61, and 31.63 nm, respectively. The cyclic voltammogram showed a cathodic peak (Epc) at 0.49 V with an anodic counterpart (Epa) at 0.49 V [E1/2 = 1.748 V]. The optical band gaps of Al2O3, Cu-Al2O3, and Ni-Al2O3 were 3.8, 3.2 and 3.65 eV, owed a cathode. It is observed that the electrochemical behavior of Ni-Al2O3 was identical to that of Al2O3 and Cu-Al2O3. The anodic and cathodic peak values rise with the scan rate. The one-electron oxidation and reduction processes are reversible, as seen by the shifting cathodic peak value toward higher negative values. All cycles exhibit absorption has a constant anodic current. This result indicated the diffusion-based redox process.

The antioxidant activity of Stachys maritima was determined via initial tests, yielding a DPPH IC50 value of 0.114 ± 0.001 mg/mL, indicative of its ability to neutralize free radicals and mitigate oxidative stress. Moreover, the plant extract demonstrated a significant iron chelation capacity comparable to EDTA (IC50: 5.98 ± 0.10 mg/mL). Analysis of the extract revealed high levels of flavonols, flavonoids, phenolic compounds, proanthocyanidins, and tannins, notably totaling 1039.48 ± 6.53 mg GAE/g and 276.21 ± 4.38 mg CAE/g, respectively, contributing to its robust antioxidant potential. ST‐CQDs, nanoscale carbon structures, have garnered interest in biomedicine for their antioxidant properties. Confirmatory analyses showed their high antioxidant activity with DPPH IC50 value of 0.69 ± 0.03 mg/mL and iron chelation capacity of 3.86 ± 0.41 mg/mL. Antimicrobial tests revealed S. maritima efficacy against various pathogens, while ST‐CQDs showed no effect. High peak areas in analyses suggest specific compounds' presence, notably certain fatty acids, highlighting their crucial role in composition understanding. Notably, 9,12,15‐Octadecatrienoic acid's importance is underscored. These findings provide a significant basis for further exploring TNF development's molecular mechanisms.
