当外科医生不能确定肿瘤的边缘时,问题出现了。切除过多,他们面临伤害病人的风险;切除过少,他们可能会留下一些癌细胞。现在,研究人员开发出一种外科手术刀,可以在切除组织时根据产生的烟,立即断定该细胞是癌变的还是健康的。这一改装的手术刀是通过分析脂质进行工作的,细胞膜大部分由脂肪细胞构成。在过去几年中,化学家表示,特定脂质的比例可用于判定多 The problem arises when the surgeon can not pinpoint the edge of the tumor. Excessive resection, they face the risk of injury to the patient; less resection, they may leave some cancer cells. Now researchers have developed a surgical scalpel that instantly determines whether the cell is cancerous or healthy based on the smoke it produces when the tissue is removed. The modified scalpel works by analyzing lipids, the majority of which are made up of fat cells. In the past few years, chemists said that the proportion of specific lipids can be used to determine more
