Architecture and dimensions of lubricin-mimetic (mimLUB). (A) Structure of the pAA-graft-PEG bottlebrush polymer mimLUB. In our study, x ≈ 185, y ≈ 650, m ≈ 45, and MW ≈ 1,400 kDa. (B) Atomic force microscopy height micrograph of mimLUB chains spin-coated onto freshly cleaved mica, scale bar = 50 nm. (C) Number-average contour length lN and number-average molecular diameter dN. Images = 6, molecules = 875. (D) Schematic representations of mimLUB with lN, dN, and DH.
