The meson-meson interaction in the scalar sector in the presence of a nuclear medium is studied with particular attention to the change of the properties of the f 0 (980) and a 0 (980) resonances. By using a chiral unitary approach which generates the f 0 and a 0 resonances and reproduces their free
