Lipoplex-Functionalized Thin-Film Surface Coating Based on Extracellular Matrix Components as Local Gene Delivery System to Control Osteogenic Stem Cell Differentiation

Figure 5 from Catharina Husteden et al. 2023 “Lipoplex-Functionalized Thin-Film Surface Coating Based on Extracellular Matrix Components as Local Gene Delivery System to Control Osteogenic Stem Cell Differentiation”: A–D) Topography images [Cs/Col]4Cs (A), [Cs/Col]4Cs/LPX (B), [Cs/Col]4Cs/LPX/Cs (C), and [Cs/Col]4Cs/LPX/Cs/Col determined by AFM [Scale bar 1 µm] (D). E) Distribution curves of Young's modulus (E0) with a force map of a defined area (see also Figure S4, Supporting Information of the cited article). NANOSENSORSTM uniqprobe triangular qp-BioT AFM probes were used for the quantitative imaging to investigate the surface roughness and topography (in a standard liquid cell of a commercially available atomic force microscope) and force mapping. The uniqprobe qp-BioT AFM probe types offer an alternative to silicon nitride probes, with the advantage of taller AFM tips with smaller opening angles and reduced thermal drift.

The development of smart multifunctional biomaterials with the ability to control the behavior of stem cells on demand has become a powerful strategy in regenerative… Read More »Lipoplex-Functionalized Thin-Film Surface Coating Based on Extracellular Matrix Components as Local Gene Delivery System to Control Osteogenic Stem Cell Differentiation

Rapid access to discrete and monodisperse block co-oligomers from sugar and terpenoid toward ultrasmall periodic nanostructures

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
