distribution of ligands on the surface more specifically. Often cell signaling events require clustering of ligand receptors on the surface of cells, and that's what we hope to induce by mixing comb polymers modified with multiple ligands with those ...

and temporal scales at which these waves operate, one can not think of biology as a functional block separate from physics. If you want to guess what the productivity will be at a given location and time in the future, you can not use a purely biolog...
