I wrote a paper about the social and ethical implications of nanomedicine–i.e., the use of nanoscale technologies as applied to medicine–which has just come out in the American Journal of Bioethics. It was featured as a target article, which means that various people wrote responses to the paper and then I got to write a response to the responses. I cannot post their responses, but you can read the response to the responses if you like. For access to the responses to which I responded, you need a subscription to AJOB, which you should have; it’s a fantastic journal! I thank Summer Johnson, Ellen McGee, Ron Sandler, and Tihamer Toth-Fejel for their dialogue, and please pass along any comments on the original paper.
