Book excerpt: Small things add up: trillions of dollars of products applying nanotechnology have been marketed to consumers promising new medicines, strong packaging to protect goods from contamination, stronger eyelash mascara and long-lasting lipstick, construction materials for housing, cheaper energy, and new drugs to fight cancer. Nanotechnology applications to consumer products represent a huge slice of daily economic life, heralding a revolutionary age for science and technology. How can the benefits of nanotechnology be realized while protecting public health? Global Health Impacts of Nanotechnology Law: A Tool for Stakeholder Engagement fills a major void in legal, scientific policy discourse about nanotechnology for people who are curious about nanoscience, bioethics, and law. The pioneering, plain-language text of Dr. Ilise L. Feitshans, international health law scholar and former international civil servant, enables readers to move comfortably across disciplines and explore how nanotechnology can reshape both commerce and public health to improve daily life worldwide.
