The rheology of molecular brushes remains challenging to control due the multiple length scales and relaxation processes involved lack direct observation conformation during flow. We use dynamics simulations determine shear thinning unentangled bottlebrush polymers with varying architecture, from linear chains combs, densely grafted bottlebrushes, star-like star polymers. find exponents in line...

The effect of a cationic-neutral diblock polypeptide on the conformation of single DNA molecules confined in rectangular nanochannels is investigated with fluorescence microscopy. An enhanced stretch along the channel is observed with increased binding of the cationic block of the polypeptide to DNA. A maximum stretch of 85% of the contour length can be achieved inside a channel with a cross-se...
