Abstract

original image

In Reih und Glied: Die einzigartige molekulare Architektur eines selbstorganisierten Polypeptidtemplats ermöglicht das elektrostatische Abscheiden von Nanopartikeln mit einheitlichem Partikelabstand. Die hierarchisch ablaufende Selbstorganisation des Polypeptids führt zu einer periodischen Anordnung geladener Flecken entlang der Fibrillenarchitektur (siehe Bild).
