Bi-layer sandwich film for antibacterial catheters
Beilstein J. Nanotechnol. 2017, 8, 1982–2001, doi:10.3762/bjnano.8.199
- , silver is also toxic. 5. The whole film may not deteriorate the qualities of conventional catheters, in particular, it must remain biocompatible with materials that are admitted by the FDA regulations. Our answers to these challenges are: 1. We consider necessary a double-sided coating for optimum impact

- chromosomes repositioning [276]. Some different gene regulations were attributed to these changes in chromosomes positions [276]. In a different work, a dramatic drop of SMC proliferation on micropillars was reported and was argued that the deformation of the nuclear lamin was responsible of this change in
Unraveling the neurotoxicity of titanium dioxide nanoparticles: focusing on molecular mechanisms
Beilstein J. Nanotechnol. 2016, 7, 645–654, doi:10.3762/bjnano.7.57
- investigate the relationship between brain damage and TiO2 NPs-mediated autophagy dysfunction. Epigenetics Another potential mechanism of TiO2 NPs is epigenetic regulations. Epigenetic changes were reported to be implicated in nanotoxicity [10][11]. Epigenetics refers to all heritable alternations in gene

Beilstein J. Nanotechnol. 2015, 6, 1769–1780, doi:10.3762/bjnano.6.181
- Classification, Labeling, and Packaging (CLP) regulations when those are classified by the Commission as hazardous chemical substances [15]. The Biocidal Products Regulation (BPR) has special provisions for biocidal materials that consist of nanoparticles, aggregates, or agglomerates in which at least 50% of
Gas sensing properties of nanocrystalline diamond at room temperature
Beilstein J. Nanotechnol. 2014, 5, 2339–2345, doi:10.3762/bjnano.5.243
- devices to improve the environmental and safety regulations of toxic gases in particular within buildings, underground structures, and airports. Semiconducting solid-state gas sensors can be considered as the most promising, portable, miniaturized gas sensors because of their minimal power requirements

- 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

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

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
