This study aims to explore the potential of using Aloe vera extract for the green synthesis of silver nanoparticles (AgNPs) and to evaluate their antibacterial properties and effectiveness in wound-healing. AgNPs were synthesized hydrothermally, employing Aloe vera as a natural reducing and stabilizing agent. The antibacterial activity of these AgNPs was tested against Escherichia coli and Staphylococcus aureus using zone inhibition and MTT assays. The wound-healing capabilities were assessed through a scratch assay on fibroblast cells. Results indicated that the AgNPs exhibited significant antibacterial activity, increasing effectiveness with higher concentrations of Aloe vera used in synthesis. AgNPs were characterized via UV–VIS spectroscopy, SEM, and DLS, showing spherical shapes ranging from 255.5 ± 5.02 nm to 749.47 ± 24.12 nm, decreasing with increasing Aloe vera concentration. Biocompatibility assessments on L929 cells showed low cytotoxicity, with over 70% cell viability at 10 mg/mL. Wound-healing assays indicated faster closure due to enhanced cell migration and matrix deposition, likely due to the synergistic effects of AgNPs and Aloe vera's bioactive components.

The nanostructures were synthesised using the pulsed Nd-YAG ablation technique, which entailed submerging small, high-quality tin particles in deionised water. The particles were coarsely crushed manually, filtered, and compacted into a solid tablet for 60 min using a 5-t hydraulic press. This production method utilised a pulse count of up to 200 laser shots, a wavelength of 1064 nm, spot size of 2.3 mm, focal length of 10 cm, and an energy of 500 mJ to examine the influence of surface shape on antibacterial activity levels.

Scanning electron microscopy (SEM) of the surface showed distinct and reasonably homogenous semispherical nanoparticles (NPs) rather than the expected porosity. The NPs exhibited an average size of 193.53 nm, in agreement with electron dispersive spectroscopy (EDS), which indicated that the oxygen-to-tin ratio closely approximated that of tin oxide (SnO2). In addition, the vibrational spectra measured with a Fourier transform infrared (FTIR) spectrometer indicated the synthesis of amber-coloured SnO2 NPs, confirming their formation by the preparation process, as well as their light scattering and absorption characteristics. In addition, using UV–visible spectroscopy, the resulting energy gap was 2.4 eV, within the normal range of energy gap for SnO2. The generated NPs were discovered to suppress the growth of fungi and bacteria, indicating that they may prevent the development of these entities.
