The semi permeable lipid bilayer cell membrane separates different ion concentrations (charges) on the inner and outer side of the membrane. Therefore, the cell membrane has the electrical properties ...
Assessing heart cells: The FET sensor array measures electrical signals in a 3D cardiac tissue construct. (Courtesy: Yue Gu) Using a novel electronic sensor array, researchers in the US have captured ...
A new technique creates cell-surface-based glycan arrays that are more lifelike than the usual ones assembled by attaching glycans directly to solid supports. Glycans, carbohydrate oligomers, decorate ...
Scientists at the Scripps Research Institute (TSRI) have described a new technique for adding glycans to cells and screening interactions between glycans and proteins. Their study (“Cell-Based Glycan ...
The circuit described here is a 12-V dc to 5-V dc (±5%) switched-mode power supply (SMPS). The supply uses a 12-V input from an array of four 3-V dc, 40-mA solar cells connected in series. (The cells ...
