Lithium niobite (LiNbO3) nanostructure were successfully synthesized by chemical bath deposition method (CBD) and then decorated with silver nitrate (AgNO3) through UV activation method at different immersion durations (5, 15, 25, 35, and 45 s). The silver nanoparticles (AgNPs) effects on the optical and structural properties were studied and analyzed using various scientific devices and technique. X-ray diffraction (XRD) results showed that all the samples have a hexagonal structure with a maximum diffraction peak at the (012), and the existence of silver atoms could be recognized at 2θ = 38.2° which corresponds to the (111) diffraction plane. The optical absorption of nanocomposites depicted the presence of plasma peak related to silver (Ag) at 350 nm. The estimated energy gap from the optical absorption revealed a reduction in the Eg value from (3.97 eV) to (3.59 eV) with the presence of Ag atom. The Photolumincence (PL) peaks were observed at around 355 nm for pure LiNbO3/Si and 358, 360, 363, 371, 476 nm for different immersion durations respectively, in the visible region of the electromagnetic spectrum. The scanning electron microscopy (SEM) study illustrated that with increasing the immersion time, especially at 45 s, a change in the particle morphology was observed (LiNbO3 NRs structure). Atomic force microscopy (AFM) displayed that the surface roughness decreases from 80.71 nm for pure sample to 23.02 nm for the decorated sample as the immersion time is increased. FT-IR manifested a noticeable increase in the intensity of the peaks of samples decorated with AgNPs. Raman spectroscopy elucidated that the peaks shifted to higher intensity due to the plasmonic effect of Ag nanoparticles. Ag–LiNbO3/Si heterojunction nano-devices were fabricated successfully and enhanced the optoelectronic properties in comparison with the pure LiNbO3/Si heterojunction device.

Background: Atropa acuminata plant, which is also known as the maitbrand or Indian belladonna, belongs to the family Solanaceae and is closely related to the deadly nightshade of Europe and North Africa used in the treatment of various diseases. Objectives: The main objective is to investigate the antidiabetic potential of silver nanoparticles of Atropa acuminata. Methods: In this study green synthesis of silver nanoparticles was carried out. The current study engross the green synthesis of A. acuminata roots by reducing silver ions, where ultraviolet (UV) spectral analysis and transmission electron microscopy confirmed nanoarchitecture. The optimized silver nanoparticles were characterized for shape, size and morphological features by various techniques viz., SEM, TEM EDXA and XRD. The optimized formulation was further subjected for lipid peroxidation assay and in vitro antidiabetic assay in order to understand the antidiabetic potential of formulated silver nanoparticles. Results: The Silver nanoparticles of Atropa acuminata roots was successfully prepared by optimizing different concentration of plant extract at different temperatures and stirring speed. The Resultant optimized nanoparticles showed a particle size around 20 nm and -28 mv zeta potential. Further the characterization of optimized AgNPs was carried out. SEM provides the shape, size, and morphological features, whereas EDXA confirms the compositions and distribution of nanoparticles through spectrum and elemental mapping. XRD diffraction analysis revealed the crystalline structure of nanoparticles. Further, Nanoparticles showed a maximum scavenging potential of 82.633±0.116 for superoxide anion free radicals at 100 µg/mL concentration. Among two anti- diabetic assays, the αamylase assay shows a better result of percent inhibition 63 ± 1.32 at 75 μg/ml concentrations. Lastly, in vitro, drug release study revealed a 101.50% cumulative release from Ag- NPs formulation up to 1 hour, which was better than the standard one. Conclusion: This study explores the novel technology of green synthesis for various biomedical applications.

“…There is currently a large volume of scientific literature related to methods for the synthesis of metallic nanomaterials and metal oxides. In this sense, metal oxide nanoparticles have been generating great interest in the scientific community because they are considered non-toxic and of low cost, besides being versatile to be designed in various types of nanostructures, not being alien to the zinc oxide nanoparticles (ZnO NP) [ 1 , 2 ], where diversity of applications are being explored due to their photocatalytic properties, in photo-electronics, photovoltaic cells and sensors [ 3 ], besides being biodegradable and having the capacity to be absorbed by the body because they can be dissolved in ions, becoming elements applied to the nutritional cycle, as well as being applied in in-vivo bio-detection, although there are still many questions to address and investigate about biodegradability and the consequences on the nutritional cycle [ 4 ]. Thus, and considering the intrahospital contamination at the level of bacteria, fungi, and viruses, research is being carried out on the application of ZnO NPs in different formats, being textile impregnation the most developed because they would prevent the transmission of dangerous pathogens that remain on textile surfaces for long periods [ 5 ].…”
