On 17 March 2022, Ineke Malsch discussed Ethics of Nanomedicine during the course on ethics of biomedical research organised by the VISION project. Nanomedicine is applied in e.g., mRNA COVID-19 vaccines, and enables digital twins, organ on chip and wearables. Introducing nanomaterials in the body raises nanosafety issues. Ethical issues are e.g., related to freedom, equality, data protection and biosecurity. Researchers should contribute to Responsible Research and Innovation, Dr Malsch explained during the session. The principles inclusiveness, anticipation, openness and responsiveness are leading. The preparation of the lecture was supported by the RiskGONE project.
