C’est essentiellement dans le domaine du diagnostic que l’on attend les avanc\u00e9es les plus importantes, dans la cr\u00e9ation d’instruments de diagnostic in\u00e9dits par exemple: une seule goutte de sang suffit (plus de tube capillaire) et en l’espace de quelques minutes, le m\u00e9decin peut d\u00e9celer, \u00e0 l’aide d’une puce, si le patient souffre d’un infarctus du myocarde, d’une infection ou de toute autre maladie grave telle qu’un cancer. Il ne s’agit l\u00e0 que d’une projection dans le futur mais les premiers instruments qui pourraient concr\u00e9tiser au moins une partie de cette vision sont d\u00e9j\u00e0 en voie de d\u00e9veloppement. Comme ces nouveaux instruments utilis\u00e9s dans le diagnostic auront besoin d’une plus petite quantit\u00e9 de r\u00e9actifs, les co\u00fbts d’analyse seront donc r\u00e9duits. Ces instruments, de format miniature, pourront prendre place dans une poche et ce, non seulement \u00e0 l’h\u00f4pital ou dans un cabinet mais \u00e9galement dans des r\u00e9gions plus retir\u00e9es de par le monde. Ces puces pourraient \u00e9galement \u00eatre b\u00e9n\u00e9fiques dans la lutte contre le paludisme en offrant  un d\u00e9pistage rapide et \u00e9conomique de la maladie dans les pays les plus pauvres.<\/p>\n\n\n\n

Les chercheurs tentent actuellement de d\u00e9velopper de meilleurs nano-nez (voir illustration 2): des instruments de diagnostic qui pourraient d\u00e9celer de fa\u00e7on extr\u00eamement rapide et pr\u00e9cise des quantit\u00e9s infimes d’une substance d\u00e9termin\u00e9e et ce, m\u00eame sous forme gazeuse. De tels instruments pourraient \u00eatre utilis\u00e9s \u00e0 des fins diverses comme par exemple dans l’examen de l’haleine du patient. L’haleine fournit de multiples renseignements relatifs \u00e0 d’\u00e9ventuelles maladies telles que diab\u00e8te ou dysfonctionnements r\u00e9naux.<\/p>\n\n\n\n
