Classically, cellular signalling is investigated measuring different optical or elec. properties of either single cells or microliter vols. of suspensions of live cells. Here we show how ligand binding to cell surface receptors and subsequent signalling re ...
In order to predict metal bioavailability by microorganisms in natural waters, analytical speciation techniques such as the permeation liquid membrane (PLM) are required. A planar sheet PLM has been characterized by measuring Pb fluxes in the absence and p ...
The GABA-synthesizing enzyme GAD65 is synthesized as a soluble cytosolic protein but undergoes post-translational modification(s) to become anchored to the cytosolic face of Golgi membranes before targeting to synaptic vesicle membranes in neuroendocrine c ...
We have previously shown that labelling intensities for synaptic proteins vary strongly among synaptic boutons. Here we addressed the questions as to whether there are heterogeneous levels of integral membrane synaptic vesicle proteins at distinct active r ...
Patterning of micro- and nanometer scale structures by means of nanostencils (shadow masks) is increasingly being used as a simple, clean and low-cost alternative to photolithography. It can be shown, that sub-100-nm scale features can be fabricated throug ...
The goal of this work was to produce water-soluble fluorescent semiconductor nanocrystals suitable to interact specifically with biomolecules and thereby creating hybrid supramolecular structures composed of nanocrystals and proteins. Hydrophobic TOPO-coat ...
Spatial compartmentalisation is a prerequisite for the creation of living matter. Without the existence of clearly defined borders, differentiation and diversity at the cellular level would not be possible. Most scientific disciplines that deal with dissol ...
We present a method that allows the on-demand release and mixing of zepto- to femtoliter vols. of solns. in the interior of vesicular nanoreactors. The reactors comprise a nested system of lipid vesicles, part of which release their cargo in the interior o ...
This paper discusses the self-assembly of block copolymers into vesicular morphology. After a brief state of art of the field, a system based on an amphiphilic poly(butadiene)- b-poly(-L-glutamic acid) (PB- b-PGA) diblock copolymer in aqueous solution is d ...
Systems for positioning and/or analyzing samples such as cells, vesicles, cellular organelles, and fragments, derivs., and mixts. thereof, for elec. and/or optical anal., esp. relating to the presence and/or activity of ion channels. [on SciFinder (R)] ...
