Using molecular dynamics simulations, we study the effect of the brush grafting density and degree of polymerization of the side chains on conformations of brush layers made of charged bottle-brush macromolecules. The thickness of the brush layer first decreases with increasing brush grafting density; then, it saturates and remains constant in the wide interval of the brush grafting densities. ...

BACKGROUND AND STUDY AIMS Endoscopic retrograde cholangiopancreatography (ERCP) with a cytological sample is a valuable tool in the diagnosis of the aetiology of biliary stricture. Our aim was to evaluate whether a more dense Infinity® cytological brush is more sensitive in diagnosing malignancy than the regularly used brush.
