Nanotechnologies : le débat tourne court

Abstract:
Une réunion publique sur les nanotechnologies a été perturbée hier soir par des opposants qui dénoncent « une mascarade ». Les « nanos », qu'on présente comme une révolution, suscitent bien des inquiétudes.

À l'échelle du nanomètre, un milliardième de mètre, les propriétés de la matière changent. La nanoscience a déjà des applications concrètes ou fait l'objet de recherches avancées dans l'industrie textile, l'électronique ou la cosmétique. Mais certains s'inquiètent d'un développement incontrôlé aux conséquences inconnues, dangereuses peut-être.
