Abstract

original image

Mikrogelstrukturen wie kugelförmige Mikrogelhüllen (Bild oben links) und kugelförmige Mikrogelpartikel, die Quantenpunkte, magnetische Nanopartikel und Polymermikropartikel enthalten (übrige Bilder), wurden mit einer Kapillar-Mikrofluidik-Technik hergestellt. Das Volumen der Partikel nimmt bei Temperaturänderungen ab oder zu, was z. B. für Anwendungen im Wirkstofftransport genutzt werden kann.
