Nanoscale: a new era for health sector

Two decades ago, Meirelles wrote a doctoral dissertation in which he analyzed the miniaturization of devices, evolution of human productive processes, and its association with the reduced need for socially necessary work2. Devices that are smaller, lighter, and easier to transport and that have more ingenious and particular characteristics have enabled gradual distancing from the sources of raw materials. Miniaturization has followed and partly induced the development of transformations in production, namely through changes in labor and social functional aspects. Device miniaturization has had an important role in increasing productivity of human labor throughout the centuries
