Nanomechanics of Cation–π Interactions in Aqueous Solution1. Issue 14 (28th February 2013) - Lu, Qingye
Abstract The first direct probing of the nanomechanics of cation–π interactions in aqueous media was accomplished by using a surface forces apparatus with complementary theoretical simulations. The tetraethylammonium (TEA) ion breaks the adhesion between poly‐L‐tryptophan (PTrp) and poly‐L‐lysine (PLL) with a 100 times higher sensitivity relative to the K+ ion (PS=polystyrene, PTyr=poly‐L‐tyrosine, and ACh=acetylcholine).
