The Isoniazid concentration in the expanded brush is ~ 14 % higher than in the bulk solution , and the concentration nearly doubles in the collapsed polymer , suggesting stronger binding between Isoniazid and the polymer compared to water , even at temperatures below the lower critical solution temperature ( LCST ) where the polymer is hydrophilic .
