Injection of ligand-free gold and silver nanoparticles into murine embryos does not impact pre-implantation development
Beilstein J. Nanotechnol. 2014, 5, 677–688, doi:10.3762/bjnano.5.80
- , AgNP injected, sham injected, handling control. Blastocysts were pooled in groups of ten. Per treatment group, 7 pools were examined. Pools were lysed in 40 µL of lysis-binding buffer, then 1 pg of rabbit globin mRNA (BRL, Gaithersburg, MD) was added as an external standard. Poly(A)+-RNA was prepared
Apertureless scanning near-field optical microscopy of sparsely labeled tobacco mosaic viruses and the intermediate filament desmin
Beilstein J. Nanotechnol. 2013, 4, 510–516, doi:10.3762/bjnano.4.60
- and might give insight in the patho-mechanism. The tobacco mosaic virus (TMV) is a tubular shaped plant virus with a length of 300 nm and a diameter of 18 nm. It is composed of 2130 identical capsid protein subunits helically arranged on a single RNA strand thereby enclosing an inner longitudinal
Size variation of infrared vibrational spectra from molecules to hydrogenated diamond nanocrystals: a density functional theory study
Beilstein J. Nanotechnol. 2013, 4, 262–268, doi:10.3762/bjnano.4.28
- sometimes used in solid-state physics and nanocrystals [21][24]. It is also used in large molecules, such as RNA [25][26]. Conclusion As concluding remarks, we can note that the present theory can adequately reproduce many of the experimental data of infrared vibrational frequencies. This includes the 330
Electrospinning preparation and electrical and biological properties of ferrocene/poly(vinylpyrrolidone) composite nanofibers
Beilstein J. Nanotechnol. 2013, 4, 189–197, doi:10.3762/bjnano.4.19
- , there are a series of chemical reactions between Fc and the enzymes, DNA and RNA in the cell due to the penetration of Fc, leading to cell death [32]. The Fc conveys many unique properties such as low toxicity, stability, lipophilicity, aromaticity and easy access to one-electron oxidation potential
FTIR nanobiosensors for Escherichia coli detection
Beilstein J. Nanotechnol. 2012, 3, 485–492, doi:10.3762/bjnano.3.55
- 1402–1457 cm−1, bands due to carbohydrates, glycoproteins, lipids and their characteristic C–O–H in-plane bending peaks and C(CH3)2 symmetric stretching were present. Finally, in the range 900–1100 cm−1, peaks due to the DNA/RNA backbone and phosphate groups of nucleic acids due to the symmetric and
Distinction of nucleobases – a tip-enhanced Raman approach
Beilstein J. Nanotechnol. 2011, 2, 628–637, doi:10.3762/bjnano.2.66
- the respective nucleobases is possible, and this eventually led to successful TERS measurements on a single RNA strand of a cytosine homopolymer [19]. The dependency of the electromagnetic field enhancement of TERS on the composition of the substrate, amongst other parameters, was shown in three
- , and hence in this case the effect relies on an isolated tip, resulting in a much smaller enhancement [20][21]. Prerequisites for a metal substrate suitable for TERS experiments on single stranded DNA or RNA are an almost atomic flatness of the surface and, as the used TERS setup is operated in back
- performing TERS experiments on native DNA [14]. In contrast, TERS measurements on calf thymus DNA presented here clearly show that specific contributions of all four nucleobases can be determined. Hence, with the chosen samples poly(A), poly(U) and calf thymus DNA typical molecules covering DNA, RNA and
