3.3 Slit Confinement - Chain in Uniaxial Confinement

The blob length scale is set by the size of the slit, D. The polymer chain executes a random walk within the slit, with a radius (2-dimensional) given by

≈ D(N∕g)1∕2 ≈ bN 1∕2
(11)

That is, the result is as above. We will see later that for real chains which make a self-avoiding random walk/possess excluded volume interactions, this will not be the case.
