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 ...

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 ...

A complete, ready-to-teach GCSE Biology lesson exploring diffusion and the movement of substances across cell membranes. Students develop their understanding of diffusion, concentration gradients and ...

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