Un nano-ordinateur constitué de 17 molécules




Il contient 16 molécules périphériques et une molécule centrale. C'est en stimulant celle-ci à l'aide d'un microscope à effet tunnel que l'on peut lancer un calcul, qui sera effectué en parallèle par les molécules périphériques. Chaque molécule pouvant être dans quatre états différents, le système offre 4,3 milliards de combinaisons.

Il est parvenu à piloter un nano-ascenseur capable de bouger d'un nanomètre.

Les applications, encore lointaines, sont néanmoins nombreuses, prometteuses et effrayantes. Des nanorobots autonomes (c'est bien le cerveau de ces petites bêtes qui pourrait découler de ces rercherches) pourraient pénétrer sans problème dans le corps humain et y effectuer les tâches pour lesquelles il a été programmé : destruction d'une tumeur ; nettoyage des artères ; ou bien à l'inverse section du nerf périphérique ; infection par un virus ; ou plus lointain, sous réserve que le nanorobot sache construire un émetteur, géolocalisation ; ou même en connaissant mieux le cerveau effacement de souvenirs, contrôle de la pensée...

En savoir plus.
