Abstract
We herein present a simple, fast, efficient and environmentally friendly method for preparing silver nanoparticles (AgNPs) using the solution plasma method in the presence of extracts from Paramignya trimera (P. trimera). The effects of P. trimera extract concentrations and the applied voltage on the formation of AgNPs were investigated. Surface plasmon resonance spectra show a strong peak at 413 nm for the prepared samples. The Fourier-transform infrared spectroscopy measurement results indicated the presence of possible functional groups in the prepared AgNPs. Morphological analysis revealed that the AgNPs were spherical with an average size of 8 nm. The prepared AgNPs exhibited good stability in solution compared to that of AgNPs prepared by the solution plasma technique without P. trimera extract. The formation mechanism of AgNPs is also proposed. The prepared AgNPs exhibited high antibacterial ability against Gram (+) Staphylococcus aureus, Gram (-) Pseudomonas aeruginosa bacteria and strong anticancer activity for the AGS gastric cancer cell line. The obtained results demonstrated that this is a simple, rapid, environmentally friendly method for preparing AgNPs instead of conventional methods using chemical reducing agents for potential applications.

Abstract
The synthesis, characterization and application of biologically synthesized nanomaterials have become an important branch of nanotechnology. In the present study, we report the synthesis of silver nanoparticles from fresh leaf extract of Centella asiatica (LEC). UV-Vis spectrum for silver colloids contains a strong plasmon band near 425[Formula: see text]nm, which confirms the formation of nanoparticles. The experimental results show that the silver nanoparticles are formed easily in the extract at ambient temperature. The resulting silver nanoparticles (AgNPs) were in the spherical form and the average size of the nanoparticles was in the range from 3[Formula: see text]nm to 30[Formula: see text]nm. From the above silver nanoparticles, we were taken up to investigate the effects of various concentrations of AgNPs on growth, development and yield of peanut plants. The results of the present experiment showed that the optimized concentration of AgNPs of the good germination, growth and pod yield of peanut plant is 5[Formula: see text]ppm.

Enhanced external quantum efficiency in GaN-based vertical-type light-emitting diodes by localized surface plasmons. Sci Rep 2016; 6:22659.

Abstract
Enhancement of the external quantum efficiency of a GaN-based vertical-type light emitting diode (VLED) through the coupling of localized surface plasmon (LSP) resonance with the wave-guided mode light is studied. To achieve this experimentally, Ag nanoparticles (NPs), as the LSP resonant source, are drop-casted on the most top layer of waveguide channel, which is composed of hydrothermally synthesized ZnO nanorods capped on the top of GaN-based VLED. Enhanced light-output power and external quantum efficiency are observed, and the amount of enhancement remains steady with the increase of the injected currents. To understand the observations theoretically, the absorption spectra and the electric field distributions of the VLED with and without Ag NPs decorated on ZnO NRs are determined using the finite-difference time-domain (FDTD) method. The results prove that the observation of enhancement of the external quantum efficiency can be attributed to the creation of an extra escape channel for trapped light due to the coupling of the LSP with wave-guided mode light, by which the energy of wave-guided mode light can be transferred to the efficient light scattering center of the LSP.

Abstract
Determination of hydrogen peroxide (H2O2) with high sensitivity and selectivity in living cells is a challenge for evaluating the diverse roles of H2O2 in the physiological and pathological processes. In this work, we present novel surface enhanced Raman scattering (SERS) nanosensors, 4-carboxyphenylboronic acid (4-CA) modified gold nanoparticles (Au NPs/4-CA), for sensing H2O2 in living cells. The nanosensors are based on that the H2O2-triggered oxidation reaction with the arylboronate on Au NPs would liberate the phenol, thus causing changes of the SERS spectra of the nanosensors. The results show the nanosensors feature higher selectivity for H2O2 over other reactive oxygen species, abundant competing cellular thiols and biologically relevant species, as well as excellent sensitivity with a low detection limit of 80 nM, which fulfills the requirements for detection of H2O2 in a biological system. In addition, the SERS nanosensors exhibit long term stability against time and pH, and high biocompatibility. More importantly, the presented nanosensors can be successfully used for monitoring changes of H2O2 levels within living biological samples upon oxidative stress, which opens up new opportunities to study its cellular biochemistry.

Abstract
A comparative adsorption kinetics, isotherms, dissolution and surface complexation of 3,4-dihydroxybenzoic acid (3,4-DHBA) and 1,2-dihydroxybenzene (catechol) at the hematite/electrolyte interface were investigated. The kinetics at pH 10 and 298.15K suggested that the adsorption behaviour of 3,4-DHBA and catechol onto hematite surface is similar and attain same equilibration time of 60 min. The adsorption kinetics data of 3,4-DHBA and catechol fit the pseudo-second-order kinetic equation of nonlinear form best. The adsorption density of 3,4-DHBA at pH≥9 increases and thereby mimics the behaviour of catechol. The solubility of hematite depends on both pH of the suspension and concentration of adsorbate. The inner-sphere complex is formed by 3,4-DHBA and catechol onto hematite surface but the mode orientation is likely to be different in the pH range 5-8 and 9-10. The advance microscopic scanning in conjunction with the vibration spectroscopy would provide better pictorial presentation of the mode of orientation of 3,4-DHBA and catechol onto hematite surface at different pH.

Abstract
We propose a large-area SERS device with efficient fluorescence quenching capability. The substrate is based on anodic porous alumina templates with various pore size and wall thickness as small as 15 and 36 nm, respectively. The nano-patterned SERS substrate, with excellent control and reproducibility of plasmon-polaritons generation, shows very efficient enhanced Raman signal in the presence of intrinsically fluorescent molecules such as cresyl violet, rhodamine, and green fluorescent protein. This work demonstrates that, when the nanostructures are properly designed and fabricated, Raman and fluorescence spectroscopy can be used in combination in order to obtain complementary molecular informations. Theoretical simulation shows excellent agreement with the experimental findings. The enhancement factor is found to be 10(3)-10(4), with respect to flat gold surface when the molecules are supposed to be closely packed, with considerable fluorescence suppression, showing a promising disposable biosensor.

Abstract
Surface-enhanced Raman scattering (SERS) has recently been investigated extensively for chemical and biomolecular sensing. Multilayer silver (Ag) nanofilms deposited on glass slides by a simple electroless deposition process have been fabricated as active substrates (Ag/GL substrates) for arsenate SERS sensing. The nanostructures and layer characteristics of the multilayer Ag films could be tuned by varying the concentrations of reactants (AgNO3/BuNH2) and reaction time. A Ag nanoparticles (AgNPs) double-layer was formed by directly reducing Ag+ ions on the glass surfaces, while a top layer (3rd-layer) of Ag dendrites was deposited on the double-layer by self-assembling AgNPs or AgNPs aggregates which had already formed in the suspension. The SERS spectra of arsenate showed that characteristic SERS bands of arsenate appear at approximately 780 and 420 cm-1, and the former possesses higher SERS intensity. By comparing the peak heights of the approximately 780 cm-1 band of the SERS spectra, the optimal Ag/GL substrate has been obtained for the most sensitive SERS sensing of arsenate. Using this optimal substrate, the limit of detection (LOD) of arsenate was determined to be approximately 5 μg·l-1.

J Colloid Interface Sci 2009; 344:482-91.

Abstract
The influence of inorganic anions (NO(3)(-), I(-), Br(-), Cl(-), SO(4)(2-), and S(2)O(3)(2-)) and of divalent cations (Ca(2+) and Mg(2+)) on the zeta potential and on the isoelectric point of alpha-alumina in aqueous medium has been studied. The effect of the anions is highly ion specific even at salt concentrations as low as 5x10(-4) M. This unexpected finding is in line with a recent report [Böstrom et al., J. Chem. Phys. 128 (2008) 135104]. It is also in agreement with an earlier theoretical prediction [B.W. Ninham, V.V. Yaminsky, Langmuir 13 (1997) 2097]. The results are consistent with the classical Hofmeister series, except for the case of NO(3)(-). Divalent anions (SO(4)(2-) and S(2)O(3)(2-)) decrease the magnitude of the zeta potential of alpha-alumina in aqueous medium, more precisely; S(2)O(3)(2-) produced large negative zeta potential (approximately -12 to -47 mV) within the pH range of the study without the isoelectric point (IEP) of alpha-alumina. However, the SO(4)(2-) decreased the zeta potential of alpha-alumina of different magnitudes (maximum approximately 25 mV at both ends of the experimental acidic and basic pH scale) with a minor shift of the IEP (approximately 0.5 unit) toward lower pH. Ca(2+) and Mg(2+) produce zeta potentials of alpha-alumina roughly equal to that of neat alpha-alumina but slightly higher than that of Na(+) at both sides of the IEP. We have shown further that the same ion specificity or equivalently competitive ion effects occur with the adsorption density of p-hydroxybenzoate onto alpha-alumina surfaces. The sequence of anions (with common cation) for the adsorption density of p-hydroxybenzoate on the alpha-alumina surfaces follows the Hofmeister series sequence: S(2)O(3)(2-) < SO(4)(2-) < Cl(-) > Br(-) > I(-) > NO(3)(-). The divalent cations (Ca(2+) and Mg(2+)) exhibit a roughly equivalent effect on the adsorption of p-hydroxybenzoate onto alpha-alumina surfaces. Using the frequency shifts of nu(as)(-COO(-)) and nu(s)(-COO(-)) in the DRIFT spectra of p-hydroxybenzoate after adsorption and other characteristic peaks, we have demonstrated that p-hydroxybenzoate forms outer-sphere complexes onto alpha-alumina surfaces at pH 5 and 6 and inner-sphere complexes at pH 7, 8, and 9 in the presence of 5x10(-4) M NaCl(aq).

Abstract
Surface-enhanced Raman Spectroscopy (SERS), surface-enhanced infrared absorption spectroscopy (SEIRA), temperature-programmed desorption (TPD), and density functional theory were used to characterize the adsorption properties of the hydroxybenzoic acid (HBA) isomers including ortho-hydroxybenzoic acid (OHA), meta-hydroxybenzoic acid (MHA), and para-hydroxybenzoic acid (PHA) using various deposition solvents with different polar properties. SERS typically enhances the Raman shifts of the monolayer, while SEIRA is a longer range effect, often providing vibrational enhancement to both the monolayer and multilayer. TPD analysis showed that OHA adsorption to silver is weaker than MHA/PHA, most likely as a result of the strong OHA intramolecular hydrogen-bonding. SERS and SEIRA demonstrated that OHA ionized efficiently in the monolayer and multilayer independent of the solvent polarity because of OHA's low pK(a) (2.98). MHA/PHA ionized better than OHA in the multilayer in less polar deposition solvents, and a decrease in the polarity of the deposition solvent created additional ordering in the MHA monolayer while inducing stronger adsorption in the PHA monolayer. It is believed that a lower level of solvation with less polar deposition solvents allowed for more adsorbate/substrate interaction and more intermolecular attraction. The addition of more MHA to a multilayer resulted only in stronger SEIRA peaks. As a PHA multilayer thickened there was significant structural changes represented by new bands and spectral peak shifts with greater intermolecular attraction as the multilayer approached bulk properties. Due to the range of applications involving HBA isomers, these studies could find significant applications in biochemistry, medicine, nanotechnology and environmental science.
