Molecular recognition induced mechanics: isotope effects in the interaction between gas phase substances and polymer-coated microcantilevers
Abstract
A novel Porous-Silicon-Over-Silicon (PSOS) chemomechanical microcantilever sensor for the isotope discrimination of gas phase substances is presented. A strong isotope effect is observed in the guest induced PSOS microcantilever bending curves of novel poly-4-vinylpyridine (P4VP) coated microcantilevers. Isotopologues of
