The potential to isolate and regulate the biodynamics of single cells is significant in drug design and screening. However, pre-existing experimental reports in single-cell drug screening must yet ...

As the gradient decays, the position of this threshold value moves at varying speed along the membrane, depending on the cell shape. Thus, via this hierarchy of protein concentration profiles, the ...

a) A classical morphogen (pink) elicits differential gene expression (represented by the black, red and blue bars) by activating different genes at different concentrations. b) One example of such a ...

A morphogen gradient is an important concept in developmental biology, because it describes a mechanism by which the emission of a signal from one part of an embryo can determine the location, ...

Scientists designed autonomous nanovesicles capable of following glucose concentration gradients, even through the blood brain barrier in rats. Brain-computer interface technologies help people regain ...

Active transport is a process that is required to move molecules against a concentration gradient. The process requires energy. For plants to take up mineral ions, ions are moved into root hairs, ...

The transport of ions is essential to maintain electrophysiological balance on either side of the membrane, called osmotic balance, which is needed for signals to be transduced from their chemical ...

Biophysicists at Ludwig-Maximilians-Universitaet (LMU) in Munch have developed a new theory, which accounts for the observation that cells can perceive their own shapes, and use this information to ...

Watch this video to see how living things use active transport to move substances against a concentration gradient. Active transport is a process that is required to move molecules against a ...
