Example Cards​
​
Card 1: Nano-drug Delivery
Description: Using nanoparticles to deliver drugs directly to diseased cells, improving the efficiency of drug delivery and minimizing side effects.
Benefits: Targeted treatment, reduced drug waste, minimized side effects.
Drawbacks: Possible unforeseen reactions in the body, high costs.
Ethical Considerations: Could such treatments be accessible to everyone given the high costs? What happens if nanoparticles don't degrade and remain in the body?
Card 2: Nano-filters for Clean Water
Description: Using nanotechnology to create filters that can remove the tiniest contaminants from water, ensuring safe drinking water.
Benefits: Access to cleaner and safer drinking water, potential for use in crisis areas or regions without access to clean water.
Drawbacks: Production costs, potential accumulation of nanoparticles in the environment.
Ethical Considerations: Can these be deployed in regions without access to clean water without exploiting the region or its resources?
Card 3: Nano-enhanced Solar Cells
Description: Integrating nanotechnology into solar cells to improve their efficiency and energy capture.
Benefits: More efficient solar energy, reduced reliance on fossil fuels, environmentally friendly.
Drawbacks: Manufacturing costs, potential environmental impact if not disposed of properly.
Ethical Considerations: Should governments subsidize such technologies for the greater good? How to ensure responsible disposal?
Card 4: Nano-wearables for Health Monitoring
Description: Wearable devices that use nanosensors to monitor vital signs, detect health abnormalities, and even administer basic first aid.
Benefits: Continuous health monitoring, early detection of health issues, convenience.
Drawbacks: Privacy concerns, potential for false positives, reliance on technology for health.
Ethical Considerations: Who has access to the data? Could this lead to discrimination by insurance companies based on health data?
Card 5: Nano-food Packaging
Description: Food packaging that uses nanoparticles to detect contamination or spoilage, ensuring food safety.
Benefits: Reduction in foodborne illnesses, longer shelf life for products, reduced food waste.
Drawbacks: Long-term implications of nanoparticles in contact with food not fully known, environmental impact of disposal.
Ethical Considerations: How to ensure that nanoparticles don't end up in the food? Is it ethical to prioritize longer shelf life over potential health implications?
Participants would use these cards to evaluate, discuss, and prioritize the nanotechnologies based on their values and the potential societal impacts.
