癌症的检测一直是困扰医生的方法之一,检测过程不仅复杂,还会对患者造成伤害,近日,来自URV的研究人员开发出一种无机化学专利便携设备,可以检测出血液中的肿瘤细胞,这种设备可以计算血液样本中肿瘤细胞的数量,因此可以实时高效的提高监测,治疗和诊断的癌症的效率。



研究人员开发出检测血液中肿瘤细胞的新设备】癌症的检测一直是困扰医生的方法之一,检测过程不仅复杂,还会对患者造成伤害,近日,来自URV的研究人员开发出一种无机化学专利便携设备,可以检测出血液中的肿瘤细胞,这种设备可以计算血液样本中肿瘤细胞的数量,因此可以实时高效的提高监测,治疗和诊断的癌症的效率。

该系统已经成功测试各阶段的乳腺癌病人,也可以通过分析血液样本中存在的不同抗体来确定其他癌症。

癌症患者在治疗期间需要不断监控评估疾病的发展,目前,医生通常使用成像技术和侵入性活检,新设备的开发具备高度敏感的特性,不需要手术,也不涉及任何辐射,因此在临床方面非常有用,因为它提高了病人的生活质量,免去了通过移除更多侵入性传统程序的必要性。

该设备可以准确地确定患者的健康水平,并可以快速的监测癌症,便宜,有效,而且无创。此外,它可以协助疾病的早期诊断,监测肿瘤的方式更有效,对患者的负面影响更小。

新设备使用两个系统的缩影:分别为流系统和光学系统,第一个使血细胞流动对齐,而第二个使用两个光学纤维分析,来计算癌细胞和非癌细胞。通过两者之间的比率,来揭示癌症是如何进展的。这个复杂系统的研究结果发表在《自然组织》科学报告中。
