  Mapping out the eight main nodes of nanotechnology discourse that have
emerged in the past decade, we explore how various scientific, social, and
ethical islands of discussion have developed, been recognized, and are being
continually renegotiated. We do so by (1) identifying the ways in which
scientists, policy makers, entrepreneurs, educators, and environmental groups
have drawn boundaries on issues relating to nanotechnology; (2) describing
concisely the perspectives from which these boundaries are drawn; and (3)
exploring how boundaries on nanotechnology are marked and negotiated by various
nodes of nanotechnology discourse.
