Miniaturization of an Osmotic Pressure-Based Glucose Sensor for Continuous Intraperitoneal and Subcutaneous Glucose Monitoring by Means of Nanotechnology.

The Sencell sensor uses glucose-induced changes in an osmotic pressure chamber for continuous glucose measurement. A final device shall have the size of a grain of rice. The size limiting factor is the piezo-resistive pressure transducers inside the core sensor technology (resulting chamber volume: 70 µL.

Inhibitory inputs to an inhibitory interneuron: Spontaneous postsynaptic currents and GABA receptors of A17 amacrine cells in the rat retina.

Amacrine cells constitute a large and heterogeneous group of inhibitory interneurons in the retina. The A17 amacrine plays an important role for visual signalling in the rod pathway microcircuit of the mammalian retina. It receives excitatory input from rod bipolar cells and provides feedback inhibition to the same cells.
