Abstract

original image

Groß und klein, kurz und lang: Mit einem pH-sensitiven Polymer beschichtete Nanopartikel (NPs) gehen ein reversibles Kettenwachstum ein, das von der pH-abhängigen elektrostatischen Interpartikelabstoßung bestimmt wird. Durch stufenweise Änderung des pH-Wertes konnten unterschiedlich große NPs zu linearen Ketten gekuppelt werden, die an Blockcopolymere erinnern (siehe Bild).
