Synthesis is based on the reduction of AgNO 3 in aqueous SDS solution by hydrogen. These nanoparticles are ...
The formed nanoparticles were characterized through UV spectroscopy, XRD, TEM particle size analysis and TGA. Fig. 4 depicts the TEM images of the biosynthesized silver nanoparticles with the extracts of blueberry and blackberry. The XRD patterns shows the definite peaks of silver indicating the ...
Nanoscale particles 1–100 nm in size are known as nanoparticles (NPs). NPs exhibit unique physical, chemical, and biological properties compared to bulk materials and possess crystal structures, higher surface-to-volume ratios, and controlled targeting and release properties. The fields of drug deli...
UV-vis spectra were measured with a type UV-2450 spectropho- tometer (Shimadzu, Suzhou, China). Fourier transform infrared (FT-IR) spectra were recorded on the Nicolet 170SX instrument (Madison, WI) in the transmission mode using KBr pellets of the sample. Thermogravimetric (TG) data were ...
The present investigation explores the adaptability of a microwave assisted route to obtain silver nanoparticles by the reduction of AgNO 3 with vanillin, an environmentally benign material. Anionic surfactants such as AOT and SDS were used separately for encapsulating AgNPs and their role was compared...
Silver nanoparticles (Ag. NPs) have shown a biological activity range, synthesized under different environment-friendly approaches. Ag. NPs were synthesized using aqueous crude extract (ACE) isolated from Plantago lanceolata. The ACE and Ag. NPs were cha
nanoparticles. The Ag nanoparticles synthesized in each extract solution was analyzed using UV–Vis spectroscopy. Reduction of Ag ions using BO-leaf extract is confirmed by the UV spectrum which exhibited a strong absorption peak at ~ 415 nm, which ultimately confirmed the formation of BO-AgNPs...
The UV-visible absorption spectra were recorded using V-630 UV/VIS spectrophotometer in the range of 1000–200 nm. The shape and particle size distribution of the nanoparticles were determined by using transmission electron microscope JEOL-JEM-1011, Japan. Thin film thickness was measured using ...
Silver nanoparticles dispersed into a resin are deposited on silica glasses by the spin coating method and heated around 100掳C. UV-VIS measurements show high stability of the optical spectra after heat treatment, suggesting that the morphology of the silver nanoparticles are stable. The transmission...
To further verify the results, the biosynthesized AgNPs were subjected to UV–vis spectroscopy analysis to confirm the formation and stability of nanoparticles. The absorption spectra which produced a maximum absorption peak at λ max 412 nm, 425 nm, and 430 nm revealed biosynthesized AgNPs...
