Abstract
This article outlines a few representative areas of research in nano- and neuroscience and then considers the complex continuum of entangled research practices that results. The point of this review is to give a realistic sense of the distributed, opportunistic character of this research, and to show how such emergent practices challenge conventional assumptions about how ethics and science should be advanced. It evaluates the risk profile of research related to that type as if it designated some discrete project. It turns out that summary judgments dismissing any ethical novelty in nanoscience depend on implicit assumptions about the nature of ethical reflection, and these, in turn, depend on assumptions about the nature of pure and applied science. An ethic of nano/neuro convergence needs to explore how these new models might help us more appropriately to manage the complex possibility space associated with emerging research.
