Graphical Abstract

Biogerüst funktionalisiert: Ein Verfahren wird vorgestellt, um feine Biokieselsäurestrukturen mit funktionellen Oxiden zu belegen. Durch dendritische Amplifikation von Oberflächen-Hydroxygruppen und anschließende Sol-Gel-Behandlung lassen sich dünne Schichten von SnO2 auf die Kieselsäure-Valven von Diatomeen aufbringen (siehe Bild). Die SnO2-bedeckten Valven fungieren als empfindliche Detektoren für NO-Gas.
