Investigating organic multilayers by spectroscopic ellipsometry: Specific and non-specific interactions of polyhistidine with NTA self-assembled monolayers

SOLANO, ILARIA CAVALLERI, ORNELLA CANEPA, MAURIZIO

Background: A versatile strategy for protein-surface coupling in biochips exploits the affinity for polyhistidine of the nitrilotriacetic acid (NTA) group loaded with Ni(II). Methods based on optical reflectivity measurements such as spectroscopic ellipsometry (SE) allow for label-free, non-invasive monitoring of molecule adsorption/desorption...

Atomic Force Microscopy and Spectroscopic Ellipsometry combined analysis of Small Ubiquitin-like Modifier adsorption on functional monolayers

Solano, Ilaria Parisse, Pietro Gramazio, Federico

The comprehension of mechanisms of interaction between functional layers and proteins is relevant for the development of sensitive and precise biosensors. Here we report our study which combines Atomic Force Microscopy and Spectroscopic Ellipsometry to investigate the His-Ni-NTA mediated interaction between 6His-tagged Small Ubiquitin-like...
