In this paper, filamentous fungi have been used as biotemplates to integrate gold nanoparticles (Au-NPs) into the cell wall. A new chemical mechanism has been proposed to elucidate the assimilation of Au-NPs by fungi, considering the ionic current that arises in the function of fungal metabolism. After biological components were eliminated, mycelium-like gold microtubes have been obtained using different fungal species as precursors.

- Two biosystems utilizing filamentous fungi and palladium (Pd) nanoparticles were developed and examined, revealing distinct accumulation patterns of Pd-NPs on fungal cells.
- One fungal species demonstrated the internalization of Pd-NPs, indicating potential for further catalytic research.
- A novel method for creating palladized biohybrids was introduced, showcasing their effectiveness in the hydrogenation reaction of 3-methyl-2-buten-1-ol, with high Pd content enhancing catalytic activity.
This communication describes a general method for templating fungal filaments with gold nanoparticles that results in a gold replica of filaments after calcination of the biological template.
