Abstract: The invention relates to the use of nanoparticles of acrylic copolymers as antineoplastic agents due to their cytotoxic effect on different types of cancerous cells. The nanoparticles have diameters of between 6 and 100 nm and and on their surfaces they carry carboxyl groups from the acrylic acid units intercalated in the polymer chain. This size permits the nanostructures to enter the malignant cells and penetrate the nucleus where the carboxyl groups interfere in the DNA replication, with which they cause the death of the cell. The nanoparticles of acrylic copolymers are prepared by the semi-continuous heterophase polymerisation method, developed by our group and for which there are patents pending [patent applications MX/a/2014/015574 and MX/a/2016/017041].
