How do you envision the nano city? Does it excite or frighten you? What actions must we take today to achieve the desired future and prevent the worst from happening?

Visions of nano-enhanced cities are laden with utopian images of shiny buildings, soaring architectures, and symbiotic human-environmental systems. However, there also are more troubling scenarios of ‘grey goo’ and robotic spiders that will devour humankind. Join us at this month's Science Café as we explore a variety of nanotechnologies applicable to city environments with respect to benefits, risks, sustainability, and governance.

Science Cafés are free, informal discussions that bring together members of the community and university scientists to discuss how science and technology can change the future. In the typical café, a scientist speaks for 5-15 minutes on a topic and the rest of the time is open to the public for questions.
