Influence of gold, silver and gold–silver alloy nanoparticles on germ cell function and embryo development
Beilstein J. Nanotechnol. 2015, 6, 651–664, doi:10.3762/bjnano.6.66
- applied in extremly small sizes in conjuction with high dosages (<2 nm, 1014 NP per embryo). (iii) Concerning oocytes and embryos silver nanoparticles are considerable more toxic than gold nanoparticles, with a clear dependency on the applied dosage. A clearly defined toxic threshold is difficult to
Functionalized polystyrene nanoparticles as a platform for studying bio–nano interactions
Beilstein J. Nanotechnol. 2014, 5, 2403–2412, doi:10.3762/bjnano.5.250
- resistance and cannot be applied orally. Such drugs could be encapsulated within nanoparticles protecting the drug, generating a new hydrophilic surface, improving pharmacokinetics and targeting the drug to distinct cells and tissues This would enable a reduction of the drug dosage thereby improving the
Nanobioarchitectures based on chlorophyll photopigment, artificial lipid bilayers and carbon nanotubes
Beilstein J. Nanotechnol. 2014, 5, 2316–2325, doi:10.3762/bjnano.5.240
- largely used as drug delivery vehicles, showing potential in targeting specific cancer cells [18] with a necessary dosage lower than conventional drugs, without harming healthy cells and significantly reduced side effects. Another interesting property of carbon nanotubes is their antioxidant activity
Influence of surface-modified maghemite nanoparticles on in vitro survival of human stem cells
Beilstein J. Nanotechnol. 2014, 5, 1732–1737, doi:10.3762/bjnano.5.183
- drugs to specific types of cells in a body, in order to greatly reduce both the needed dosage and the side effects of the drug [6][7][8]. At the same time, the long-term fate of the particles and their possible cytotoxic effects on cells of the human body have to be taken into account to evaluate
Precise quantification of silica and ceria nanoparticle uptake revealed by 3D fluorescence microscopy
Beilstein J. Nanotechnol. 2014, 5, 1616–1624, doi:10.3762/bjnano.5.173
- nanoparticles. The flow is generated by a novel microfluidic reactor that can be combined with live-cell imaging and is able to cover the entire physiological range of shear rates [31]. Comparison to other methods Customary techniques performed for achieving the dosage of particles taken up by cells include
Mimicking exposures to acute and lifetime concentrations of inhaled silver nanoparticles by two different in vitro approaches
Beilstein J. Nanotechnol. 2014, 5, 1357–1370, doi:10.3762/bjnano.5.149
- in epon [71]. From the embedded cells, ultrathin sections were cut parallel to the vertical axis of the inserts, mounted on copper grids and stained with uranyl acetate. Imaging was done with a Philips CM12 TEM (FEI Co Philips Electron Optics). Estimation of NP dosage in dispersion over time The in
Electron-beam induced deposition and autocatalytic decomposition of Co(CO)3NO
Beilstein J. Nanotechnol. 2014, 5, 1175–1185, doi:10.3762/bjnano.5.129
- brightness of the deposits and the cluster growth mode are in line with the autocatalytic growth of EBID deposits upon dosage of additional Co(CO)3NO. The samples were further characterized at the PolLux soft X-ray STXM beamline [28] at the Swiss Light Source using a zone plate with a nominal resolution of
- autocatalytic decomposition upon further precursor dosage. The two precursors show very different growth characteristics under the applied reaction conditions. Structure fabrication by using Co(CO)3NO is strongly affected by the applied electron dose in the EBID step and subsequent autocatalytic growth time
- deposits at an enlarged photon energy scale, along with the spectrum of a Co layer produced by PVD as reference (grey). Evaluation of the X-ray absorption data for the growth of Co-containing deposits by EBID plus autocatalytic growth upon Co(CO)3NO dosage. a) Optical density (left vertical axis) and
Antimicrobial properties of CuO nanorods and multi-armed nanoparticles against B. anthracis vegetative cells and endospores
Beilstein J. Nanotechnol. 2014, 5, 789–800, doi:10.3762/bjnano.5.91
- deadly B. anthracis spores and vegetative cells. However the limited work still underscores the potential of a nanomaterial-mediated decontamination of BW agents. Prasad et al. [13] have reported some degree of deactivation of B. anthracis cells by UV light assisted TiO2 nanoparticles at a dosage ranging
- first 30 min of exposure to CuO nanoparticles (P5). Interestingly even 0.5 mg/mL dose of the NPs was capable of killing over 99% of B. anthracis vegetative cells. Afterward, up to 4 h the rate of decrease was not that high, even for higher dosage up to 6 mg/mL P5 NPs. In terms of absolute data after
Spontaneous dissociation of Co2(CO)8 and autocatalytic growth of Co on SiO2: A combined experimental and theoretical investigation
Beilstein J. Nanotechnol. 2012, 3, 546–555, doi:10.3762/bjnano.3.63
- injection system for 30 min, causing a pressure increase to 3 × 10−5 mbar, which dropped within ten minutes to about 6 × 10−6 mbar. The gas injection system employs a stainless-steel precursor capsule with a fine-dosage valve. The precursor temperature was set by the ambient conditions to 27 °C. From the

- the high-energy yield for the simulated film curve; and (3) the maximum height hmax of the silver nanoparticles by comparing the low-energy tail of silver with that of the homogenous silver film. In order to study the surface density and the total particle number (i.e., the dosage) of silver in the
