Molecular self-assembly

Molecular self-assembly and nanoscience

Although the vast bulk of reported work involves biological molecules, the use of the OWLS grating coupler sensor is by no means confined to them. Due to the high precision with which an assembly process can be followed, the OWLS grating coupler sensor became an essential tool for investigating the fundamentals of self-assembly.
