were purified/functionalized by the using acid treatment method.
Fourier transform infrared (FTIR) spectroscopy (Nicolet IR200, Thermo Scientific, USA) was used to confirm the alkylation of the neat GNPs
. KBr powder was mixed with a GNPs
sample at 99:1 weight ratio then a disc-shaped pellet was prepared for the FTIR analysis.
Figure 3 shows the photoluminescence spectra of GNPs
doped homogeneous planar NLCs, where the concentrations of GNPs
are 5*[10.sup.9] particles/ml, 9*[10.sup.9] particles/ml, 1.3*[10.sup.10] particles/ml, 1.8*[10.sup.10] particles/ml, and 2.5*[10.sup.10] particles/ml, respectively; and the gold nanoparticle size is 13 nm in diameter.
The enhancement of the MacEtch process achieved using photoillumination was attributed to the trapping of light by the GNPs
on the Si substrate surface, which improved the etching efficiency.
Gold Nanoparticles (GNPs
) are amongst one of the most extensively studied areas since the first report of gold colloids by Faraday dates back to more than 100 years ago (2).
To determine the cytotoxic effects of 5-ALA, GNPs
and their combination, experiments were performed in four groups.
Morphological and Spectroscopy Characterization of GNPs
Considering the fact that GNPs
are relatively stable and nontoxic, we explored the antibacterial activity of the synthesized GNPs
against gram positive and gram negative bacteria.
In fact, malpractice litigation is at a very low rate for NPs and particularly for GNPs
, as indicated by the low insurance premiums for GNPs
-- approximately $200-$300 per year.
Nursing homes typically employ GNPs
primarily to improve care to patients.
The aim of the present study was to assess the potential of three grades of GNP
, differing in their preparation processing and resulting sizes, on PP/GNP composites properties.
The as-prepared GNPs
were characterized by transmission electron microscopy (TEM, Tencai F20).
