etal nanoparticles attached to carbon-based nanostructured materials enable new nanoelectronic solutions for energy
storage (e.g. fuel cells, supercapacitors) [1] as well as in chemical, biochemical [1,2,4] and optical sensors [2,3,4]. A
requirement for electronic sensors is the design of a versatile nanoelectronic transducer. In the ideal case, such a component
can be functionalized with nanoscopic building blocks in a modular manner that allows selective response and tuning of
the sensitivity. Nanoelectronic field-effect transistors (FETs) using individualized single-walled carbon nanotubes (SWCNTs)
have been proposed for this case as FET channel material [5,6]. Recently, we presented a scalable on-chip functionalization
approach for single-walled carbon nanotubes between palladium electrodes in the geometry of a field-effect transistor with
preformed gold nanoparticles [5]. This method is wafer-level compatible and comprises two stages of flow chemistry. In a new
chemical approach, we propose the deposition of SWCNTs by inkjet printing, followed by a microfluidic deposition of the
nanoparticles. The concept for this type of FET channel is shown in the following schematic representation.
