答案与题解：
1．B 本题选项A在第一段第三句提到，选项C在第二段倒数第二句和第四段第一句提到，选项D则在第四段第二、三、四句提到，只有选项B全文均未提及。

2．C 第三段最后两句说到，如果存在靶分子的话，量子点就会发光，以此辨认疾病，这正是本题答案。

3．A 第四段全段都在讲纳米技术如何提高药物疗效，而中心就在于纳米技术能使药物对准疾病病灶(文章中实际是举已经研发的治癌药为例)从而提高药物疗效。

4．C 第五段第二句已经说得很清楚，其中并没有Iran。

5．D 第五段第三、四句说到，纳米材料的颗粒在体内和在体外环境中作用可能不太一样，因此可能存在某种危险性。

其实言外之意还存在未知数，所以后一句才说需要更多投入以便搞清它们的危险性。
