需要权衡纳米粒子的毒性和纳米医学的潜力。2010年,亚利桑那州艺术史教授伊夫林·索伦森(Evelyn Sorensen)成为一名II期宫颈癌患者,当时癌细胞已经扩散到淋巴结。由于她的生命只有一年时间了,医生告诉她说:告别家人,去度假吧。就像在报纸上的报道中所描述的那样,索伦森不甘心接受这个令人沮丧的预测,坚持要查看临床试验清单,结果她了解到马萨诸塞州坎布里奇的一项试 There is a need to weigh the toxicity of nanoparticles and the potential of nanomedicine. In 2010, Evelyn Sorensen, a professor of history in Arizona, became a stage II cervical cancer patient at a time when cancer cells had spread to the lymph nodes. Because of her life only one year, the doctor told her: goodbye family, go on holiday. As described in the newspaper article, Sorensen was unwilling to accept this depressing prediction and insisted on reviewing the list of clinical trials, and as a result she learned of a test at Cambridge, Mass.
