Characterization of Surface Modifications by White Light Interferometry: Applications in Ion Sputtering, Laser Ablation, and Tribology Experiments

White light microscope interferometry is an optical, noncontact and quick method for measuring the topography of surfaces. It is shown how the method can be applied toward mechanical wear analysis, where wear scars on tribological test samples are analyzed; and in materials science to determine ion beam sputtering or laser ablation volumes and...

Electroplating is a process that uses electric current to reduce dissolved metal cations so that they form a thin coating on an electrode. Other thin film deposition techniques include chemical vapor deposition (CVD), spin coating, dip coating, and sputter deposition among others. CVD uses a gas-phase precursor of the element to be...

Biolayer Interferometry Technology to Detect Interactions between Ligand and Analyte

Biolayer Interferometry Technology to Detect Interactions between Ligand and Analyte

In this video, we demonstrate biolayer interferometry (BLI) technology to detect the intermolecular interactions between ligands and target analytes in real-time. BLI measures changes in the interference pattern of white light reflected off a layer of immobilized ligands on a biosensor surface as they interact with analytes in...
