The purple phototrophic bacteria synthesize an extensive system of intracytoplasmic membranes (ICM) in order to increase the surface area for absorbing and utilizing solar energy. Rhodobacter sphaeroides cells contain curved membrane invaginations. In order to study the biogenesis of ICM in this bacterium mature (ICM) and precursor (upper pigmented band -(More)
The capillary filling speed of wetting liquids of varying viscosity and surface tension in hydrophilic nanochannels with an elastic capping layer has been analyzed. The channels, with a height just below 80 nm, are suspended by a thin flexible membrane that easily deforms due to the negative pressure which develops behind the moving meniscus. In the(More)
We show an approach based on a combination of site-directed mutagenesis, NIL and multivalent host-guest interactions for the realization of engineered ordered functional arrays of purified components of the photosynthetic system, the membrane-bound LH2 complex. In addition to micrometer-scale patterned structures, we demonstrated the use of nanometer-scale(More)
In this paper we analyze the characteristic shape of the liquid meniscus at the fluid air interface in nanochannels of less than 80 nm height capped by a flexible membrane. Because of the induced negative pressure difference between the liquid pressure and the pressure outside, the 0.18 microm thin membrane on top of the channels bends downward. This(More)
This data article contains seven figures and two tables supporting the research article entitled: spatiotemporal proliferation of human stromal cells adjusts to nutrient availability and leads to stanniocalcin-1 expression in vitro and in vivo[1]. The data explain the culture of stromal cells in vitro in three culture systems: discs, scaffolds and scaffolds(More)
