Nanoscopic surfactant behavior of the porin MspA in aqueous media
Beilstein J. Nanotechnol. 2013, 4, 278–284, doi:10.3762/bjnano.4.30
- strength and especially the temperature on the size of the MspA-vesicles and their zeta potentials, ζ. The influence of temperature on the 3D-aggregation behavior of peptides is rarely discussed, because the temperature is well defined in many living organisms and only a few proteins do not denature at
Controlled deposition and combing of DNA across lithographically defined patterns on silicon
Beilstein J. Nanotechnol. 2013, 4, 72–76, doi:10.3762/bjnano.4.8
- stretching of various DNA–peptide conjugates. These nanomaterials have been recently prepared by our team and are composed of a dsDNA core and peripheral coating layer of self-assembled cationic peptides [21][22]. Results and Discussion As was mentioned above, DNA molecules acquire a relatively compact
- –peptide conjugates, while the original recipe was proven to be ineffective for combing these materials [11]. Figure 3 represents the topography of combed dsDNA conjugated with various peptides. Combing across nanoelectrodes was also possible for DNA–peptide conjugates (Figure 3e). The gas-phase deposition
- , Sigma Aldrich) was used as a buffer in all the procedures described here. The DNA solution was buffer exchanged to ammonium acetate before use, to guarantee that only “volatile” ions are present on the substrate. The following peptides were used to form DNA–peptide conjugates: indolicidin, abbreviated
Self-organizing bioinspired oligothiophene–oligopeptide hybrids
Beilstein J. Nanotechnol. 2011, 2, 525–544, doi:10.3762/bjnano.2.57
- of amyloidogenic peptides to self-assemble and form extremely stable and tough nanostructures has been realized, and thus they are now actively probed as building blocks for various nanotechnology applications by covalently binding them to synthetic moieties [7][8][9][10], and engineering fusion
- peptides to other molecular compounds. Conjugates of synthetic and natural macromolecules are of great current interest because of their promising biomedical, microelectronic, and other advanced technological applications [7][8][9][10][14][15]. Covalent attachment of synthetic polymer blocks to
- of particular interest. The conjugation of oligothiophenes and amyloidogenic peptides may result in new compounds that supplement the potentially semiconducting, optical, and electroluminescent properties of oligo- and polythiophenes with the self-assembling, specific binding, and stimuli responsive
Detection of interaction between biomineralising proteins and calcium carbonate microcrystals
Beilstein J. Nanotechnol. 2011, 2, 222–227, doi:10.3762/bjnano.2.26
- this mechanism, it would be advantageous to characterise the different proteins purified from bio-composites by their ability to bind to different minerals selectively. Such a characterisation assay or protocol is even useful for the design of peptides mimicking the biomineralisation process. It would
- be possible to evaluate the synthesis results of different peptides in terms of their mineral or ceramic binding capability. Turning to proteins purified from nacre from a marine shell or of a shell forming animal, it would be helpful to determine which proteins are involved in nacre or shell
Magnetic nanoparticles for biomedical NMR-based diagnostics
Beilstein J. Nanotechnol. 2010, 1, 142–154, doi:10.3762/bjnano.1.17
- spontaneous aggregation, which could mimic target-induced clustering; 3) have high magnetization and transverse relaxivity (r2) to induce pronounced T2 changes; and 4) have good surface chemistry to simplify conjugational procedures for attaching affinity molecules, such as antibodies and peptides.
