Anticancer efficacy of a supramolecular complex of a 2-diethylaminoethyl–dextran–MMA graft copolymer and paclitaxel used as an artificial enzyme
Beilstein J. Nanotechnol. 2014, 5, 2293–2307, doi:10.3762/bjnano.5.238
- regulations for animal experiments and related activities at Oita University (license no. N009001). To evaluate the antitumor effect of the DDMC/PTX complex, tumor-bearing mice were prepared by inoculating B16F10 melanoma cells subcutaneously in the back of C57BL/6 female mice (2.0 × 106 cells/mouse). On
A reproducible number-based sizing method for pigment-grade titanium dioxide
Beilstein J. Nanotechnol. 2014, 5, 1815–1822, doi:10.3762/bjnano.5.192
- of forthcoming national and international regulations concerning the classification of nanomaterials. Scientific efforts towards standardized number-based sizing methods have so far been concentrated on model systems, such as spherical gold or silica nanoparticles. However, for industrial particulate
- example, and therefore allows reliable classification of this material according to forthcoming regulations. Keywords: electron microscopy; particle size; pigment; sizing; titanium dioxide; Introduction Titanium dioxide is among the ten most abundant materials on the Earth [1]. In the form of a fine
- for the characterization of particulate materials is triggered by the prospect of forthcoming national and international regulations concerning the classification of nanomaterials [3][4][5][6]. Scientific efforts to establish standardized methods for determining number-based size distributions have so
Applicability and costs of nanofiltration in combination with photocatalysis for the treatment of dye house effluents
Beilstein J. Nanotechnol. 2014, 5, 476–484, doi:10.3762/bjnano.5.55
- and finally disposed according to local regulations. The permeate stream, which is already reduced in colour and in dissolved organic compounds, is post-treated in the photocatalysis, which can again be classified as a polishing step. A more sophisticated concept is shown in Figure 4. A submerged UF
- , which is required, even if the membrane plant is not in operation. As for the amortization period, we have generously taken a 10-year period, which might not be generally applicable depending on local situations or financial regulations. Figure 5 is a compilation of empirical data of realized membrane
- out in large-volume tanks. Secondly various residual dyes from different sources have to be separated or oxidized more or less at the end of the pipe after a biological treatment step to fulfil regulations or to achieve an almost colourless effluent. The treatment of diluted systems after the
Near-infrared dye loaded polymeric nanoparticles for cancer imaging and therapy and cellular response after laser-induced heating
Beilstein J. Nanotechnol. 2014, 5, 313–322, doi:10.3762/bjnano.5.35
- VEGF amount was normalized to SRB value and the calculated results were normalized to controls. In vivo optical imaging Animal studies were performed following the regulations of the Institutional Animal Care and Use Committee. Twenty-four Nd4 Swiss Webster mice (25–30 grams, 9 weeks old) were
FTIR nanobiosensors for Escherichia coli detection
Beilstein J. Nanotechnol. 2012, 3, 485–492, doi:10.3762/bjnano.3.55
- comply with the safety regulations of the food and water supply chain. In addition, these methods are expensive, complicated, time-consuming, and require skilled personnel with expertise in molecular biology. To overcome these problems, devices that can be used in situ, and that are simple, highly
