- What part of this talk was most surprising to you? Why?
- What questions do you have about this TED talk for the presenter? What led you to these questions and/or why do you think they are important to ask?
- Dr. Smith tells us this technology should be available in the near future: “The idea here is that the separation process for screening could be as simple as processing a sample of urine, blood or saliva, which is a near-term possibility within the next few years. Ultimately, it could be used to isolate and detect target exosomes associated with a particular type of cancer, sensing and reporting their presence within minutes.” What obstacles do you expect they still may need to overcome? And using your knowledge of cell biology and research techniques, how do you think they might determine where the cancer is located based on the exosomes from a urine, blood, or saliva sample?
- Dr. Smith imagines a future in which one of these machines is in every home. What questions, concerns, or thoughts does this possibility raise for you?
