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

Fig. 7 from “Cerosomes as skin repairing agent: Mode of action studies with a model stratum corneum layer at liquid/air and liquid/solid interfaces” by F. Strati et al: AFM scans of a) SC model monolayer transferred via LB method onto mica support, b) SC model monolayer after injection of cerosomes, c) SC model monolayer after injection of cerosome + S75-3 formulation, and d) SC model monolayer after injection of S75-3 liposomal formulation. All samples were transferred via the LS method onto glass substrate. Each experiment was performed at 20°C and the subphase used for a) was Millipore water while for b), c), and d) the same aqueous solutions have been used as for the formulation of the liposomes. Topographical images were recorded in liquid state using NANOSENSORS uniqprobe qp-BioT AFM probes in a standard liquid cell containing the needed buffer.

The human skin is the second largest organ of the human body. The stratum corneum (SC) is the outmost layer of the human skin and… Read More »Cerosomes as skin repairing agent: Mode of action studies with a model stratum corneum layer at liquid/air and liquid/solid interfaces

Figure 3 from “Supercritical carbon dioxide decellularization of plant material to generate 3D biocompatible scaffolds AFM imaging and spectrometry measurement” by Ashlee F. Harris et al.: They used AFM surface topography measurements to confirm that the structures such as plant vasculature were preserved after the scSO2 process and used AFM force curves to calculate the Young’s Modulus (YM) of the scCO2 decellularized scaffold. NANOSENSORS uniqprobe qp-BioAC AFM probes were used for the described AFM measurments. (a) Representative false colored three-dimensional surface mapping images and (b) Young’s modulus of scCO2 and chemically decellularized scaffolds (data as mean ± SEM; n = 5).

Biocompatible scaffolds that can be repopulated with human cells have many uses such serving as replacement organs and tissues. Therefore there is an increasing interest… Read More »Supercritical carbon dioxide decellularization of plant material to generate 3D biocompatible scaffolds
