PURPOSE: An in vivo selective tumor suppressing method using layered dihydroxide is provided to selectively transfer anti-cancer drug to cancer tissue and prevent reduction of efficiency.;CONSTITUTION: An in vivo selective tumor suppressing method using layered dihydroxide is performed by transferring to cancer cells and increasing residence time in the body compared with administering anti-cancer drug only. A composition of LDH and anti-cancer drug has targeting function of effectively treating cancer without any side effect. The cancer is osteosarcoma. The composite of the LDH and anti-cancer drug is manufactured in 50-450 nm by hydrothermal reaction.;COPYRIGHT KIPO 2010
