“…The fruit juice (Figure A(a)) is colorless and has no absorption at wavelength in the range 800–300 nm, instead a steady increase occured at 425 nm. The aqueous solution of HAuCl 4 (Figure A(b)) is light yellow and exhibits no absorption peak at high concentration (5 mM), but it has an absorption band at 290 nm in very dilute form (not shown in Figure ) which is attributed to the ligand to metal charge transfer (LMCT) band . The initial mixture (Figure A(c)) of these two has also no noticeable band in the range of 800–300 nm.…”

“…The aqueous solution of HAuCl 4 ( Figure 1A(b)) is light yellow and exhibits no absorption peak at high concentration (5 mM), but it has an absorption band at 290 nm in very dilute form (not shown in Figure 1) which is attributed to the ligand to metal charge transfer (LMCT) band. [38] The initial mixture ( Figure 1A(c)) of these two has also no noticeable band in the range of 800-300 nm. Once the mixture reached a temperature at 45-50 0 C, after sometimes, the color of the solution started developing wine-violet, indicating the formation of particles.…”

Citrus macroptera (CM) fruit juice was used to reduce gold ions (Au3+) and to stabilize as‐formed gold nanoparticles (AuNPs). CM‐AuNPs exhibit surface Plasmon resonance (SPR) peak at 544 nm. Transmission Electron Microscope (TEM) study reveals that they are multi‐shaped, predominantly pseudo‐spherical with a diameter 20 nm. They have surface charge −30 mV and possess FCC lattice pattern. Particles could effectively inhibit the biofilm formation of Pseudomonas aeruginosa bacteria. Experimental study shows that CM‐AuNPs make the bacteria cripple to generate EPS and pyocyanin. AFM images of the structure of biofilm reveal that CM‐AuNPs indeed efficiently disrupt the biofilm structure. CM‐AuNPs in combination with Sub‐MIC dose of gentamicin against P. aeruginosa bacteria exhibit quite high efficiency. The cytotoxic effect of CM‐AuNPs against three human cancer cell line show that they are comparatively more efficient to regulate the growth of HepG2 (liver cancer cell line) than that of A 549 (adenocarcinogenic human alveolar basal epithial cell) and MDA‐MB 468 (breast cancer cell). Thus, the CM‐AuNPs could be treated as a potential anti‐biofilm and anti‐cancer agent.

The goal of this project is to obtain poly(vinyl alcohol) (PVA)/TiO2‐bovine serum albumin (BSA) nanocomposite (NC) films in different weight percentages of modified TiO2. For this purpose, to prevent the accumulation of nanoparticles (NPs) in the PVA matrix, the surface of the TiO2 NPs was treated with the BSA molecules. To achieve this aim, ultrasonic waves were used as an environmentally friendly and green process that decrease the time of reactions, help better spreading of TiO2 NPs and maintain dimensions of TiO2 NPs in the nanoscale range. In the end, the features of the PVA/TiO2‐BSA NC films were considered with a variety of techniques. The Fourier transform infrared spectroscopy, energy dispersive X‐ray, and X‐ray diffraction showed that the BSA was well placed on the surface of TiO2 NPs. The thermal gravimetric analysis and UV‐visible results demonstrated that all the PVA/TiO2‐BSA NC films have better thermal and optical properties than the pure PVA. © 2018 Wiley Periodicals, Inc. J.

“…In a quite different scenario, to stabilize thermodynamically unstable metal, nanoparticles in aqueous medium-different types of anionic as well as cationic surfactants have been widely used (Lee and Meisel, 1982;Misra et al, 2010;Huynh and Chen, 2011). Of the surfactants anions especially citrate ions are mostly used in preparation of metal nanoparticles (Lee and Meisel, 1982;Huynh and Chen, 2011).…”

In this report, we have studied the recognition of citrate anions adsorbed on the surface of silver nanoparticles (cit-Ag-NPs), by macrocyclic polyammonium cations (MCPACs): Me6 [14]ane-N4 H8 (4+) (Tet-A/Tet-B cations) and [32]ane-N8 H16 (8+) , which are well reputed anion recognizers and are treated as to mimic of biological polyamines. The study was monitored on ultraviolet-visible spectroscopy by performing a titration of the aqueous dispersion of the cit-Ag-NPs by the aqueous solution of MCPACs. The ultraviolet-visible time-scan plots over the reduction of the absorption band of surface plasmon resonance of cit-Ag-NPs at 390 nm are well fitted with fourth-order polynomial equation and are employed to determine the initial aggregation rate constants. It has been stated that the aggregation is the result in electrostatic attraction followed by H-bond formation between the surface-adsorbed citrate anions and added MCPACs. The atomic force microscopy results have evidenced aggregation of cit-Ag-NPs in presence of MCPACs. The evaluated H-bonded association constant (Kasso ) using Benesi-Hildebrand method reveals that [32]ane-N8 H16 (8+) cations form stronger association complex, as expected, with the citrate anions than the Me6 [14]ane-N4 H8 (4+) cations. The study would thus provide the insight of molecular interactions involved in nanoparticle surface-adsorbed anions with biological polyamines. Copyright © 2016 John Wiley & Sons, Ltd.
