审稿意见:“The protocol reported for the detection of real samples is not clear. The authors state “the human urine samples were centrifuged for 15 min at 10000 rpm to eliminate the interfering substances within the urine”. Why are the authors removing interfering substances? Which substances? From Figure 6 it seems that the NCs are highly selective, so there is no need for removing interferents. Are there other interferents that tend to react at pH 9.5? Could the authors list them?” 在做尿样分析时,一般文献中都会先离心,做实验的时候也是这么做的,尿样离心的目的是什么呢?去除大的蛋白质吗
