title: Nanoscale porosity in pigments for chemical sensing.
abstract: Porous pigments in which chemically responsive dyes have been immobilized in a matrix of organically modified siloxanes (ormosils) have been prepared and characterized by AFM, TEM, EDS, and optical analysis. In typical chemical sensing applications, an array of 36 different porous ormosil pigments are deposited on polyethylene terephthalate (PET) film.
