    Notizen: Abstract.  We have combined a home-built capacitance sensor with a commercial scanning force microscope to obtain a Scanning Capacitance Microscope (SCM). The SCM has been used to study Nitride–Oxide–Silicon (NOS) heterostructures which offer potential applications in charge storage technology. Charge writing and reading on a submicrometer scale is demonstrated with our SCM setup. In addition, SCM appears to be very useful for the characterization of subsurface defects in semiconductor devices which are inaccessible by most of the other scanning probe microscopies. Finally, we introduce a novel spectroscopic mode of SCM operation which offers combined voltage-dependent and spatially resolved information about inhomogeneous charge distributions in semiconductor devices.

    Notizen: Summary We describe insulin binding and insulin-mediated RNA synthesis on seven human fibroblasts strains in culture initiated from skin biopsies in the presence of three oral antidiabetic agents, Metformin, Gliquidone, and a non-sulfonylurea antidiabetic drug (B × DF 591 ZW), which belong to different chemical classes. At least at a nontoxic pharmacologic concentration of 1 µg/ml these drugs did not influence the number and affinity of insulin receptors, nor did they increase the insulin-mediated RNA synthesis. We conclude that cultured fibroblasts do not represent the proper target for an evaluation of an extrapancreatic action of oral antidiabetic drugs.
