We showed that the binding of BLG to AG is accompanied by refractive index changes, in relation with optical properties and structural changes of the complexes formed. %G English %L hal-02296790 %U https://utt.hal.science/hal-02296790 %~ CIRAD %~ CNRS %~ UNIV-MONTP2 %~ UNIV-TROYES %~ INRA %~ IATE %~ AGREENIUM %~ BA %~ UNIV-MONTPELLIER %~ UTT %~ MONTPELLIER-SUPAGRO %~ INRAE %~ INRAEOCCITANIEMONTPELLIER %~ UM1-UM2 %~ UM-2015-2021 %~ INSTITUT-AGRO
