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 ult racompact waveguiding film of amorphous TiO2 prepared by low-temperatu re microwave plasma-impulse chemical vapor deposition.
