Article Synopsis
- The rise of antibiotic-resistant bacteria has spurred research into metallic nanoparticles (especially gold and silver) as effective antibacterial agents.
- Their antibacterial properties, synthesis methods, and mechanisms of action were reviewed in studies from 2006 to 2023, confirming their effectiveness against various bacteria.
- The review emphasizes the need for standardized synthesis and testing protocols to improve the reliability of future research and accelerate the development of nanoparticle-based antibiotics.
In this study, tomato plants were grown in vitro with and without incorporation of TiO nanoparticles in Murashige and Skoog (MS) growth medium. The aim of this study was to describe the morphological (area and roundness cell) and mechanical (Young's Modulus) change in the different tissue of tomato root, epidermis (Ep), parenchyma (Pa), and vascular bundles (Vb), when the whole plant was exposed to TiO nanoparticles (TiO NPs). light microscopy (LM), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and atomic force microscopy (AFM), wavelength dispersive X-ray fluorescence (WDXRF) techniques were used to identify changes into the root cells when TiO NPs were incorporated.

These parameters provide quantitative information regarding the mechanical behavior of the tomato root under fresh conditions in different locations of the cross-section of root [cell surface of the epidermis, parenchyma (Pa), and vascular bundles (Vb)]. The results show that the mechanical parameters depend on the indented region, tissue type, and growth time.
