Selective porous gates made from colloidal silica nanoparticles
Beilstein J. Nanotechnol. 2015, 6, 2105–2112, doi:10.3762/bjnano.6.215
- were obtained, suggesting possible applications of these nanoporous films as selective gates for controlled transport of chemical species in solution. Keywords: block copolymers; coatings; colloidal nanoparticles; silica; sol–gel synthesis; Introduction The development of smart nanoporous devices for
- proved to generate a variety of well-ordered materials by self-assembling processes [31][32][33][34][35]. Here, we describe the synthesis, deposition and physicochemical characterization of silica coatings, obtained by spin-coating deposition of soft-templated silica colloidal nanoparticles onto
Characterization of nanostructured ZnO thin films deposited through vacuum evaporation
Beilstein J. Nanotechnol. 2015, 6, 971–975, doi:10.3762/bjnano.6.100
- , Benemérita Universidad Autónoma de Puebla, Ciudad Universitaria Avenida San Claudio y 14 Sur, 72570, Puebla, México 10.3762/bjnano.6.100 Abstract This work presents a novel technique to deposit ZnO thin films through a metal vacuum evaporation technique using colloidal nanoparticles (average size of 30 nm
- was chosen because is easy to handle and only the deposition time is considered a control parameter. Another reason is the use of colloidal nanoparticles with well-controlled size, which were synthesized at the laboratory of the authors [13]. Experimental The proposed thin film deposition is a novel
- The authors successfully deposited worm-shaped nanostructured thin films by vacuum evaporation using colloidal nanoparticles as the source. The transmittance for annealed thin film is up to 80%, and this result is directly correlated with the annealing. The obtained thin films have a thickness between
SERS and DFT study of copper surfaces coated with corrosion inhibitor
Beilstein J. Nanotechnol. 2014, 5, 2489–2497, doi:10.3762/bjnano.5.258
- SERS activation was ensured by the deposition of silver colloidal nanoparticles on the copper substrate where the organic molecules were already stable and present due to chemisorption [9][10][11]. Regardless, it must be taken into account that the deposited silver particles, in addition to promoting
Biopolymer colloids for controlling and templating inorganic synthesis

- nanoparticles [7]. In a different approach, biopolymers can also be applied to modify surfaces and induce the deposition of nanoparticles. For instance, Nochomovitz et al. [8] described the deposition and patterning of gold colloidal nanoparticles and carbon nanotubes on surfaces previously modified with
Current state of laser synthesis of metal and alloy nanoparticles as ligand-free reference materials for nano-toxicological assays
Beilstein J. Nanotechnol. 2014, 5, 1523–1541, doi:10.3762/bjnano.5.165
- particle properties, e.g., by inducing aggregation processes in the presence of biomolecules [20], and hence complicating bio-response studies. The removal of surfactants or residual ligands from colloidal nanoparticles is possible, e.g., by centrifugation [21], diafiltration [22] or tangential-flow
- made with nanocomposites and do not necessarily apply to colloidal nanoparticles. Furthermore, it could be demonstrated that the cytotoxicity of AuAg alloy nanoparticles is likewise affected by the presence of surface ligands [148]. Here, citrate reduced cytotoxic and antimicrobial effects, while they
- filtration [23]. However, this process is very time consuming and often results in particle aggregation. Hence, pulsed laser ablation in liquids (PLAL) has proven to be a promising alternative for the synthesis of nanoparticles applicable in toxicity assays as it provides totally ligand-free colloidal

- as a base for the subsequent modification with D-mannose, thus hindering the agglomeration of the particles when stored for long time. The coating of iron oxide colloidal nanoparticles was achieved by a post-synthesis modification with D-mannose [12]. D-mannose-coated nanoparticles were prepared at a
