This book presents mechanics miniaturization trends explored step by step, starting with the example of the miniaturization of a mechanical calculator. The ultra-miniaturization of mechanical machinery is now approaching the atomic scale. In this book, molecule-gears, trains of molecule-gears, and molecule motors are studied -one molecule at a time- on a solid surface, using scanning probe manipulation protocols and in solution as demonstrated in the European project "MEMO". All scales of mechanical machinery are presented using the various lithography techniques currently available, from the submillimeter to the nanoscale. Researchers and nanomechanical engineers will find new inspirations for the construction of minute mechanical devices which can be used in diverse hostile environments, for example under radiation constraints, on the surface membrane of a living cell or immersed in liquid. The book is presented in a format accessible for university students, in particular for those at the Master and PhD levels.

Les nanotechnologies ont le vent en poupe. On nous promet des nanorobots étonnants et des matériaux révolutionnaires, tandis que de farouches opposants invoquent le fantôme de Big Brother et agitent l'épouvantail des OAM (organismes atomiquement modifiés). Entre marketing médiatico-scientifique et angoisses immaîtrisées, la voie de la sagesse, prônée ici, rappelle que le champ des nanotechnologies est plus étroit qu'on ne se plaît à le dire, qu'il ne s'est élargi que pour des raisons de politique intérieure états-unienne, et que les enjeux éthiques restent encore très surévalués. Sous la plume d'un chercheur à l'origine de cette saga, ce petit livre apporte des réponses claires et factuelles.

Ce livre est une critique du consensus autour d'une sorte d'indéfinissabilité des « nanotechnologies » qui autoriserait chaque acteur à forger sa propre définition. C'est pourquoi, dans cet ouvrage, l'auteur s'est engagé à faire ressortir les débats autour de l'histoire du concept, de l'étymologie et de la prolifération des définitions influencée par les rivalités économiques, les enjeux stratégiques et les intérêts hétérogènes des acteurs. L'auteur cherche à dépasser ce relativisme convenu en mettant l'accent sur les instruments technologiques qui nous ont permis de contrôler physiquement les réalités à l'échelle nanométrique et de privilégier la prise en compte des changements de propriétés inhérents à l'échelle quantique où se déroule toute activité véritablement nano. Ce livre s'adresse à la fois aux chercheurs, aux étudiants et aux curieux désireux d'en savoir un peu plus sur cette technoscience révolutionnaire et les débats qui en ponctuent le développement.
