“…The absorption maximum is almost the same, with a little shift. These results are consistent with results by Zou et al [43], where with the increase of stabilizer amount, the position of maximum absorption wavelength slightly shifted towards red. In the high absorption region (where a [ 10 4 cm -1 ), involving interband optical transitions between valence and conduction bands, the absorption coefficient data as a function of wavelength are, determined using the Tauc formula, given by the following equation [44]:…”

In this study, the size-controlled synthesis of silver nanoparticles (Ag NPs) via chemical reduction method by NaBH 4 as a reducing agent and poly(vinyl pyrrolidone) or PVP as a stabilizing agent is reported. Changing of ratios between reducing agent and stabilizing agent relative to AgNO 3 -optimized conditions for synthesis of stable Ag NPs was studied. The formation of Ag NPs was tracked by UV-Vis spectroscopy, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and photoluminescence (PL) spectroscopy. Particle size distribution was studied by particle size analyzer, and the morphology was examined by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The optical properties of the synthesized Ag NPs were also investigated. The optimized Ag NPs were very stable even after 1 month that was due to effective stabilization by PVP molecules. The mechanism of Ag NPs formation and stabilization is discussed in detail.

“…The availability of ionic silver during the second heat treatment (sterilization at 170°C, Fig. 1b) could explain the enlargement of the nanoparticle size, as observed by Zou, Xu, Hou, Wu, and Sun (2007) during hydrothermal treatments. Remarkably, those silver nanoparticles were not aggregated, meaning that a certain interaction between the cellulose molten structure and the nanoparticles has taken place.…”

“…Recently LSPR has been very revalent topic of researcher for its label free bio sensing because of its high sensitivity with change in refractive index. [13][14][15][16][17] In this study we fabricated a fiber optic sensor for detection of tetracycline using silver nanoparticle and molecular imprinted hydrogel. Where tetracycline used as a template molecule.…”

We reported a simple absorption based fiber optic sensor for the detection of tetracycline using LSPR (Ag nanoparticle) and molecular imprinted polymer (MIP). For the fabrication of sensor first we unclad 1cm portion of a 17 cm long fiber. In that portion we coated silver nanoparticles, which are synthesized by hydrothermal process. Then we coated the unclad region by MIP layer that has tetracycline as a template molecule. MIP has nanocavities or binding sites of the template molecule. When template molecule comes to nanocavities then template binds with the polymer and refractive index of polymer changes. With respect to change in concentration of template molecule the light absorbed by Ag nanoparticles which has been recorded simultaneously with the spectrometer assembly
