HAVANA, Dec. 26 (Xinhua) -- Cuban scientists are designing treatment plans and medicines by using nanotechnology to fight cancer, an official said Sunday.
Marlene Porto, Director of the state-run Center for Investigation and Development of Medicines, told local newspaper Juventud Rebelde that Cuban scientists "are working on important pharmacological designs on a nanotechnological scale."
Porto talked about targeted medicines, which are used in cancer treatment. "When they are introduced in the body, they will act directly and exclusively in the place where the therapeutic result is needed."
Porto said nanotechnology allows doctors to "improve the quality and effectiveness of medicines and use a treatment that is more effective, but less invasive and toxic."
The island state has a Center for Advanced Studies in Cuba (CEAC), which is dedicated to the development of nanotechnology. CEAC was opened for Latin American scientists in September by nuclear physicist Fidel Castro Diaz-Balart, the oldest son of former leader Fidel Castro.
Cuba has developed a solid industry of research and production of biotechnology, including vaccines and medicines and technology for export. The industry is an important pillar of the Cuban economy, earning revenues totalling about 400 million U.S. dollars a year.
