Magnetic control of self-assembly and disassembly in organic materials

Figure 3 from You-jin Jung et al. 2023 “Magnetic control of self-assembly and disassembly in organic materials”: a MNP-helix rod-coils containing positively charged amino acid residues, Rx-α10-PEG16 (x = 1–4). The building blocks have two to five positive charges. b A linear plasmid DNA (7.5 kb). c Self-assembled nanostructures of R1-α10-PEG16. d EMSA on agarose gel. e The PD complexes (intermediates). Left: an AFM image, right: a TEM image. The charge ratio (+/−) was 0.7. f The PD complexes (nanoribbons). g The PD complexes (nanoribbons + artificial chromosomes). h The PD complexes (artificial chromosomes). i The molecular mechanism responsible for the formation of the nanoribbon. Atomic Force Microscopy was preformed in non-contact mode using NANOSENSORS PointProbe Plus PPP-NCHR AFM probes.

Magnetically responsive materials are highly valuable for biological and medical uses because the magnetic field is non-invasive, radiation-free, and safe for humans.* DNA and some… Read More »Magnetic control of self-assembly and disassembly in organic materials

Fig. 4 from : Rapid access to discrete and monodisperse block co-oligomers from sugar and terpenoid toward ultrasmall periodic nanostructures by Takuya Isono et al. Thin-film morphologies of Glc3-b-Sol and Glc4-b-Sol. AFM height images (a, b) and corresponding cross-sectional profiles (c, d) indicating the formation of 6–8-nm-thick horizontal lamellae in Glc3-b-Sol (a, c) and Glc4-b-Sol thin films (b, d). Thin-film samples were prepared by spin-coating the BCO solution onto the hydrophilic surface of a silicon substrate followed by thermal annealing at 85 °C for 1 h. NANOSENSORS PointProbe Plus PPP-NCHR standard silicon tapping mode AFM probes and NANOSENSORS SuperSharpSilicon high resolution silicon AFM probes were used

Discrete block co-oligomers (BCOs) can form highly ordered ultrasmall nanostructures which can be used for lithographic templates. These nanotemplates are promising for the low-cost, large-scale,… Read More »Rapid access to discrete and monodisperse block co-oligomers from sugar and terpenoid toward ultrasmall periodic nanostructures

Figure 5 from Yordanova et. al. "Zn2+-triggered self-assembly of Gonadorelin [6-D-Phe] to produce nanostructures and fibrils" - AFM image of the Zn2+: GnRH [6-D-Phe] 10:1 complex. (a,b) Oligomers after preparation with tapping mode in Tris buffer solution (c,d) fibrils with tapping mode in air (z-scale indicates the average size of the formed oligomers and fibrils). NANOSENSORS qp-BioAC AFM probe was used to perform images in buffer solution

For this article the AFM images taken with tapping mode in Tris buffer solution were performed with the NANOSENSORS qp-BioAC (cantilever 3, resonance frequency 30kHz).… Read More »Zn2+-triggered self-assembly of Gonadorelin [6-D-Phe] to produce nanostructures and fibrils
