Résumé

A simple method to prepare. at gold terraces on mica for atomic force microscopy biomolecular characterisation is described. The procedure includes preheating of the substrate, metal deposition and an annealing step. All of these steps are at elevated temperatures (300-420 degrees C). This approach allows one to prepare large. at gold terraces (200-500 nm), which constitute ideal substrates for visualisation and characterisation of a self-assembly monolayer of biomolecules at the nanoscale. The authors illustrated this potential of characterisation with the reconstitution of a protein monolayer.
