Ethical Frameworks in Nanotech

• Consequentialism evaluates the morality of nanotechnology based on its outcomes and consequences for society
  • Utilitarianism, a form of consequentialism, seeks to maximize overall well-being and minimize harm
• Deontology focuses on the inherent rightness or wrongness of actions, regardless of their consequences
  • The precautionary principle, often applied in nanotechnology, emphasizes caution and risk assessment before the implementation of new technologies
• Virtue ethics emphasizes the importance of moral character and the cultivation of virtues (honesty, compassion) in the development and application of nanotechnology
• The principle of autonomy respects the right of individuals to make informed decisions about the use and exposure to nanotechnology
• Distributive justice considers the fair allocation of benefits and risks associated with nanotechnology across different segments of society
• The principle of beneficence obligates researchers and developers to prioritize the well-being and interests of individuals and society
• The principle of non-maleficence requires the avoidance of harm and the minimization of risks in the development and application of nanotechnology
