Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>The first direct probing</bold> 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‐<sc>L</sc>‐tryptophan (PTrp) and poly‐<sc>L</sc>‐lysine (PLL) with a 100 times higher sensitivity relative to the K⁺ ion (PS=polystyrene, PTyr=poly‐L‐tyrosine, and ACh=acetylcholine).<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1x47k4d8" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
