The control of the morphology, as well as the physical and chemical properties, of nanopores is a key issue for many applications. Reducing pore size is important in nanopore-based sensing applications as it helps to increase sensitivity. Changes of

Robust 'one-component' chitosan-based ultrathin films fabricated using layer-by-layer technique

Autor: Szczepan Zapotoczny, Maria Bulwan, Maria Nowakowska

Publikováno v: Soft Matter. 5:4726

“One-component” chitosan-based multilayer films have been formed and characterized for the first time. Two derivatives of chitosan containing oppositely charged strong ionic groups were synthesized for that purpose. Low molecular weight chitosan
