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

Model for the graphite electrode Interface analysis between a model for the graphite electrode and solvent for electrolytes of lithium-ion batteries. An example of the interface observation between highly oriented pyrolytic graphite (HOPG) as a model for graphite electrodes and tetraglyme, which has been studied as a solvent of electrolytes for lithium ion batteries. The AFM cantilever oscillation frequency and amplitude during the experiments were 92 kHz and 0.3 nm, respectively. The temperature was maintained at 298 K under an argon atmosphere throughout the experiment to prevent the dissolution of contaminants from the air, which could affect the interface structure. The topographic image revealed an ordered structure at Δf = 1000 Hz, obtained with tetraglyme adsorbed on an HOPG surface.
