Abstract

Způsob enkapsulace substance v biokapsli zahrnuje přivedení roztoku do biokapsle a potom provedení změny systému biokapsle-roztok takovým způsobem, že substance zůstane enkapsulovaná, zatímco rozpouštědlo unikne. Substancí může být kyselina, např. aminokyselina histidin. Změnou systému biokapsle-roztok může být např. zvýšení koncetrace roztoku v kapsli. ŕ
