  Innovando desde lo nano
Usando láseres y nanopartículas, científicos encontraron una nueva técnica para ubicar células malignas individuales y destruirlas por medio de explosiones de nanoburbujas. El método consiste en introducir nanopartículas de oro (de aproximadamente un millonésimo de milímetro) en la célula cancerosa e iluminarlas con un láser para
generar «nanoburbujas» que las destruyen.
