Abstract
We demonstrate quantitative detection of interfacial mass changes with submonolayer sensitivity during the sorption of a small molecule at a planar surface. The optical transducer consists of a 140‐nm‐thick ultracompact waveguiding film of amorphous TiO2 prepared by low‐temperature microwave plasma‐impulse chemical vapor deposition.Keywords
