In this paper we review the use of the E<SUB>p,i</SUB>-E<SUB>iso</SUB> correlation of Gamma-Ray Bursts to measure Ω<SUB>M</SUB>. We show that the present data set of GRBs, coupled with the assumption that we live in a flat universe, can provide indipendent evidence, from other probes, that Ω<SUB>M</SUB>~0.3. We show that current (e.g., Swift, Fermi/GBM, Konus-WIND) and next GRB experiments (e.g., CALET/GBM, SVOM, Lomonosov/UFFO, LOFT/WFM) will allow us, within a few years, to constrain Ω<SUB>M</SUB> and the evolution of dark energy with time, with an accuracy comparable to that currently exhibited by SNe-Ia.STAMPAenConference paper10.1142/9789814623995_00382-s2.0-85045384951https://www.worldscientific.com/doi/abs/10.1142/9789814623995_00382015mgm..conf..769AFIS/05 - ASTRONOMIA E ASTROFISICA
