Enhanced Exiton-Plasmon Interaction Enabling Observation of Near-Field Photoluminescence in a WSe2-Gold Nanoparticle Hybrid System

Figure 2 from Anastasia Romashkina et al.2025, “Enhanced Exciton–Plasmon Interaction Enabling Observation of Near-Field Photoluminescence in a WSe2–Gold Nanoparticle Hybrid System”, Near-field optical microscope. Excitation and detection scheme in s-SNOM for the investigation of near-field photoluminescence. The s-SNOM is based on a tapping-mode atomic force microscope and uses a gold coated NANOSENSORS AdvancedTECTM ATEC-NCAu tip-view AFM probe.

Monolayer transition metal dichalcogenides, such as tungsten diselenide, have recently attracted considerable attention due to their reduced dielectric screening and direct bandgap, which result in… Read More »Enhanced Exiton-Plasmon Interaction Enabling Observation of Near-Field Photoluminescence in a WSe2-Gold Nanoparticle Hybrid System

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
