Abstract: Organic nanoscale science and technology relies on the control of phenomena occurring at the atomic level. Lately, nanoparticles and self-assembled monolayers have been used in biosensing and biolabeling applications; however, understanding of elementary nanoscopic processes in molecular film growth is in its infancy. Here we use real-time in-situ extremely sensitive capacitive detection of molecular growth process and combine it with ex situ ellipsometry and contact angle measurements. We determine the effective thickness of a completed monolayer for different molecules: (3-Aminopropyl)triethoxysilane (APTES), (3-Glycidyloxypropyl)trimethoxysilane (GPTES), (3-Mercaptopropyl)trimethoxysilane (MPTES) and 3-(Ethoxydimethylsilyl)propylamine (APDMES). We demonstrate, that our method provides a relatively simple and at the same time very precise in-situ method to monitor and optimize growth of molecular layers.
