“…The potential of plant-based nanoparticles to treat different cancers is being extensively studied and well reviewed [76] and the application of silver and gold nanoparticles to treat cancers is a very active area of research investigations [76][77][78][79][80]. Recent studies revealed that the use of the various metallic nanoparticles in medical sciences has various applications, such as bio-imaging [81][82][83][84], bio-sensing [85][86][87], and drug delivery [88][89][90] of nutraceuticals [23,26,[91][92][93][94][95][96][97][98][99], and pharmaceuticals [17,20,31,100], which could affect disposition [13,24,25,[27][28][29][30]32,33,[101][102][103][104][105][106][107]…”

In the last decade, the green synthesis of nanoparticles has had a prominent role in scientific research for industrial and biomedical applications. In this current study, silver nitrate (AgNO3) was reduced and stabilized with an aqueous extract of Thelypteris glandulosolanosa (Raqui-raqui), forming silver nanoparticles (AgNPs-RR). UV-vis spectrophotometry, dynamic light scattering (DLS), and scanning transmission electron microscopy (STEM) were utilized to analyze the structures of AgNPs-RR. The results from this analysis showed a characteristic peak at 420 nm and a mean hydrodynamic size equal to 39.16 nm, while the STEM revealed a size distribution of 6.64–51.00 nm with an average diameter of 31.45 nm. Cellular cytotoxicity assays using MCF-7 (ATCC® HTB-22™, mammary gland breast), A549 (ATCC® CCL-185, lung epithelial carcinoma), and L929 (ATCC® CCL-1, subcutaneous connective tissue of Mus musculus) demonstrated over 42.70% of MCF-7, 59.24% of A549, and 8.80% of L929 cells had cell death after 48 h showing that this nanoparticle is more selective to disrupt neoplastic than non-cancerous cells and may be further developed into an effective strategy for breast and lung cancer treatment. These results demonstrate that the nanoparticle surfaces developed are complex, have lower contact angles, and have excellent scratch and wear resistance.

“…In a follow-up article, multi-colored excitation dependent emission (MEDE) FeSe QDs functionalized with chiral and achiral molecules were prepared in aqueous state. 87 The prepared materials were used to image neurofilament network in a cell and tissue through a The confocal fluorescence microscope and femtosecond pulsed laser two-photon microscope images of U87MG glioma cells and mouse cortical tissues stained with FeSe@PEG-anti-NF displayed the excitation-dependent multi-color PL imaging (Figure 6G,H). In the U87MG cell fluorescence images, the neurofilaments were successfully visualized in the cytoplasm, and their emissive color was dynamically tuned by changing the excitation wavelength, that is, blue (405 nm), green (430 nm), cyan (800 nm), yellowish-green (875 nm), yellow (900 nm), and red (1025 nm) fluorescence (Figure 6G).…”

Fe‐based nanostructures have possessed promising properties that make it suitable for chiral sensing and imaging applications owing to their ultra‐small size, non‐toxicity, biocompatibility, excellent photostability, tunable fluorescence, and water solubility. This review summarizes the recent research progress in the field of Fe‐based nanostructures and places special emphases on their applications in chiral sensing and imaging. The synthetic strategies to prepare the targeted Fe‐based structures were also introduced. The chiral sensing and imaging applications of the nanostructures are discussed in details.
