The femtoscopy technique consists in the analysis of the correlation function in momentum space for a pair or triplet of hadrons of interest and its application to pp and p-Pb collisions measured at LHC can be employed to study final state interactions among the hadrons.The ALICE collaboration recently showed that such technique can be used also to study charmed hadrons to investigate their strong residual interaction with non-charmed hadrons.A possible extension of this technique to pairs of charmed hadrons could provide a novel and conclusive methodology to understand the structure of hadronic states such as the χc1(3872) or the Tcc+.In this talk the state of the art of such studies and the future perspectives will be discussed.
