Cientistas da Universidade Northwestern (EUA) desenvolveram uma versão do antigo quimioterápico 5-fluorouracilo (5-FU), utilizando nanotecnologia para reestruturá-lo em Ácidos Nucleicos Esféricos (SNAs). Esta inovação permite que o medicamento seja entregue de forma altamente seletiva diretamente às células cancerígenas (como as de Leucemia Mieloide Aguda), tornando-o até 20.000 vezes mais eficaz em testes com animais e eliminando os efeitos colaterais detectáveis associados ao 5-FU tradicional, ao mesmo tempo que retarda a progressão do câncer em 59 vezes.
