Societal and ethical concerns also pose barriers to the advancement of nanotechnology. The public’s perception of nanotechnology can be a significant impediment. Misinformation and lack of understanding may lead to fear and opposition. Ethical issues, such as privacy concerns related to nanoscale sensors and the potential for job displacement due to automation, also need to be addressed. Moreover, the potential for dual-use of nanotechnology in both civilian and military applications raises important ethical questions.
