As an illustration of the complexities involved in connecting physics and molecular biology at the nanoscale, in this paper I discuss two case studies from nanoscience. The first examines the use of a biological structure to build nanostructures in a controlled way. The second discusses the attempt to build a single molecular wire, and then decide whether such a wire is indeed conducting. After presenting the central features of each case study, I examine the role played in them by microscopic (...) imaging, the different styles of reasoning involved, and the various theoretical, methodological, and axiological differences. I conclude by arguing that, except for the probe microscopes that are used, there is very little in common between the two cases. At the nanoscale, physics and molecular biology seem to meet in a non-unified way. (shrink)

Images from the nanoworld are not at all disorienting or bewildering, as one might expect from contemplating the strange and surprising features that arise where classical physics comes to an end and quantum effects begin to appear. Instead, we see the traces of explorers in a world that appears to be infinitely malleable. The paper shows that the capability to visualize processes and phenomena at the nanoscale is a matter not only of research technologies and the advancement of observational techniques, (...) but also a matter of developing a visual setting that exhibits knowledge and practice, surprise and control. The surface is such a stage and so is the landscape: they invite us to become immersed and move around like someone who goes for a walk. In order to appreciate this pictorial, as well as discursive, setting we turn to “strollology” as a method of reconstructing the world that is experienced in the manner of walking. With the notion of imagescape this method is applied to the modes of partaking in the nanoworld and its specific features. Rather than articulate theoretical or metaphysical presuppositions these nanoscapes serve to validate the very idea of nanotechnology. (shrink)

Nanotechnologies produce many different types of images but are characterized by the ones that allow us to ‘see the atoms’ despite the fact that objects at the nanoscale are smaller than the wavelength of light and hence are ‘invisible’. Images from scanning probe microscopy (SPM), like ‘The Beginning’, have played an emblematic role in the constitution of the field and are also more likely to be used in communication outside the scientific field. These images are made, selected, modified and evaluated (...) with respect to the information that they communicate. The ‘life cycle’ of these images implies the transduction of this information. Outside of the scientific field, however, they are no longer defined by this information, nor according to technical and scientific criteria, but by their aesthetic power, and they become associated with other images from other fields (art, advertisement, entertainment). This process creates a psycho-social ‘halo’ about ‘nano’ in the public perception, and raises ethical issues about nanotechnological communication via images. We will analyze the halo of the nano in this respect and propose a strategy for a reflexive ‘accommodation’ to the images at the nanoscale. (shrink)
