Hydrophilic silver nanoparticles with tunable optical properties: application for the detection of heavy metals in water
Beilstein J. Nanotechnol. 2016, 7, 1654–1661, doi:10.3762/bjnano.7.157
- concentration of 1 ppm at room temperature. Our system showed sensibility mainly to nickel (II) ions. For this type of ion, we tested the sensitivity as a function of the ion concentration in the range 1.0–0.1 ppm and we estimated a limit of detection (LOD) of 0.3 ppm. Results and Discussion Silver nanoparticle
- synthesis AgNPs were synthesized by wet reduction, using sodium borohydride as a reducing agent and 3-mercapto-1-propanesulfonic acid sodium salt as a capping agent. The water solubility of the thiol induces a strongly hydrophilic character with respect to the nanoparticles, which present the sulfonate
pH-Triggered release from surface-modified poly(lactic-co-glycolic acid) nanoparticles
Beilstein J. Nanotechnol. 2015, 6, 2504–2512, doi:10.3762/bjnano.6.260
- stability limits. In particular, we find the stability limits and the released amount of PDADMA to be dependent on the assembly pH of the multilayers. Results and Discussion Nanoparticle coating Successful nanoparticle synthesis can be concluded from measurements of particle size, polydispersity index (PDI

- (C19H19N7O6) were purchased from Sigma-Aldrich. Gold interdigitated electrodes (IDE) were purchased from Dropsens. Gold nanoparticle synthesis and stabilization: Colloidal gold nanoparticles (AuNPs) were synthesized by the aqueous reduction of HAuCl4 with trisodium citrate. An amount of 100 mL of 10−3 M
Synthesis, characterization and in vitro biocompatibility study of Au/TMC/Fe3O4 nanocomposites as a promising, nontoxic system for biomedical applications

- used as the cross-linker during the polymer/Fe3O4 nanoparticle synthesis) [40]. Au/chitosan/Fe3O4 and Au/TMC/Fe3O4 nanocomposites Because of the numerous advantages of nanocomposites containing both Fe3O4 and Au, the synthesis of such hybrid structures has become one of the most quickly advancing
Heterometal nanoparticles from Ru-based molecular clusters covalently anchored onto functionalized carbon nanotubes and nanofibers
Beilstein J. Nanotechnol. 2015, 6, 1287–1297, doi:10.3762/bjnano.6.133
- commercial Pt–Ru/C catalysts. The preparation methods for Pt–Ru/nanocarbon are varied and take inspiration from (i) electrochemistry (electrodeposition) [11][12], (ii) nanoparticle synthesis (polyol procedure) [13][14] or (iii) heterogeneous catalysis (impregnation/reduction). A fixed pH value during the

Experimental Nanoparticle synthesis Monodisperse, oleic acid-stabilized SPIOs were synthesized according to Yu et al. [43]. Briefly, a mixture of 2 mmol FeOOH, 8.0 mmol
Inorganic Janus particles for biomedical applications
Beilstein J. Nanotechnol. 2014, 5, 2346–2362, doi:10.3762/bjnano.5.244
- chemistry, the crucial step of the nanoparticle synthesis is the formation of a metal seed by decomposition of an organometallic precursor prior to the nucleation of the metal oxide. Simultaneous nucleation of both components would have interdiffusion as a limiting factor. Depending on the solvents used for
The impact of the confinement of reactants on the metal distribution in bimetallic nanoparticles synthesized in reverse micelles
Beilstein J. Nanotechnol. 2014, 5, 1966–1979, doi:10.3762/bjnano.5.206
- with three different sets of micelles randomly distributed: micelles carrying Au salt (M-Au), Pt salt (M-Pt) and reducing agent (M-R). The volume fraction occupied by micelles is set at φ = 10%. Each micelle can act as a nanoreactor during nanoparticle synthesis. Thus, although initially each

One pot synthesis of silver nanoparticles using a cyclodextrin containing polymer as reductant and stabilizer
Beilstein J. Nanotechnol. 2014, 5, 380–385, doi:10.3762/bjnano.5.44
- environmental and biological risky reducing agents and solvents such as sodium borohydride, hydrazine or dimethylformamide. Consequently, the interest in a green nanoparticle synthesis using natural reducing agents like saccharides or cyclodextrin (CD) in environmentally benign solvents increased [9][10][11][12
Formation of SiC nanoparticles in an atmospheric microwave plasma
Beilstein J. Nanotechnol. 2011, 2, 665–673, doi:10.3762/bjnano.2.71
- nanoparticle synthesis is that the electrons escaping from the plasma zone are attached to surfaces in contact with the plasma, causing a negative charge at the plasma boundary and a positive bulk plasma potential. A negative charge on the nanoparticle surface suppresses their agglomeration [9][21], making the
- experimental setup [11]. In that experimental work, ten single experiments were presented and the qualitative correlations of the particle size with the process parameters were the same as in the investigation on ZnO. Nevertheless, in the case of the Si nanoparticle synthesis, an approximately five-times
