\"\"Apr\u00e8s le test \u00e0 base de particules d\u2019or<\/a> pour d\u00e9tecter pr\u00e9cocement le VIH et le cancer \u00e0 l’\u0153il nu, voici les nanoparticules d’or<\/a> radioactives contre le cancer. L’utilisation de la radioactivit\u00e9 pour lutter contre le cancer n’est pas une nouveaut\u00e9, sauf que cette m\u00e9thode est aussi nocive pour les cellules canc\u00e9reuses que pour les cellules saines. En effet, les rayons alpha, utilis\u00e9s pour d\u00e9truire les cellules malades, endommagent \u00e9galement les autres cellules et peuvent parfois causer encore plus de d\u00e9g\u00e2ts. C’est l\u00e0 qu’intervient la relique barbare \u00e0 l’\u00e9chelle nanom\u00e9trique.<\/span> Les nanoparticules d’or<\/a> sont d’ores et d\u00e9j\u00e0 utilis\u00e9es pour d\u00e9truire les tumeurs car l’or<\/a> poss\u00e8de une bonne biocompatibilit\u00e9. Concr\u00e8tement, les nanoparticules d’or<\/a> ciblent les cellules canc\u00e9reuses et y d\u00e9livrent des substances curatives, notamment gr\u00e2ce aux anticorps qui recouvrent le m\u00e9tal pr\u00e9cieux<\/a>. Cette strat\u00e9gie du cheval de Troie int\u00e9resse fortement les chercheurs, qui y voient une chance de cibler les cellules d\u00e9fectueuses. Cela reviendrait \u00e0 faire p\u00e9n\u00e9trer dans l’organisme des nano sources de rayon alpha \u00e0 l’int\u00e9rieur des cellules canc\u00e9reuses. Les nanoparticules d’or<\/a> joueraient alors le r\u00f4le de \u00ab transporteur<\/em> \u00bb des substances contenant les noyaux d’actinium radioactif.<\/span> On peut facilement imaginer les r\u00e9percussions de cette d\u00e9couverte dans le monde scientifique et m\u00e9dical ainsi que dans la finance. L’or<\/a> qui ne cesse de gagner du terrain sur le march\u00e9 des mat\u00e9riaux pr\u00e9cieux et qui repr\u00e9sente une s\u00e9rieuse alternative \u00e0 un dollars chancelant, verrait ses cours<\/a> progresser encore plus vite gr\u00e2ce \u00e0 ses propri\u00e9t\u00e9s curatives.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
