Description

一种金-上转换纳米粒子三聚体的制备方法及其应用
技术领域
本发明涉及一种金-上转换纳米粒子三聚体的制备方法及其应用,属于分析化学技术领域。
背景技术
甲胎蛋白(α-fetoprotein,AFP),是一种致癌糖蛋白,是诊断原发性肝癌的特异性肿瘤标志物,具有确立诊断、早期诊断、鉴别诊断的作用。大量的临床发现,70%-95% 的原发性肝癌患者的AFP 升高。粘蛋白-1(Mucin-1)发生在许多腺癌,包括胰腺癌、肺癌、乳腺癌、卵巢癌、结肠癌和其它组织。粘蛋白也过度表达在肺疾病,如哮喘、支气管炎、慢性阻塞性肺病或囊性纤维化。Mucin-1正诊断标记为恶性肿瘤和其他疾病过程中,通常会过度或错误表达。
传统检测癌症标志物的方法有:酶联免疫法、电化学和基于仪器的液质联用、高效液相色谱等。酶联免疫法检测肿瘤标志物时,因蛋白质容易热变性,所以很难检测蛋白类肿瘤标志物,另外酶联免疫法的灵敏度较低,而且耗力耗时;电化学对样品的基质要求较高,很难实施;而用仪器检测时成本很高,并且对操作人员的操作技能有很高的要求。
所以,本发明提出了一种新型的、简便的、灵敏的检测方法,把纳米材料作为一种新型探针,进行AFP和Mucin-1的超灵敏检测。
通过 DNA 杂交将20nm粒径的金纳米粒子和20nm粒径的上转换纳米粒子组装成三聚体结构。目标物AFP和其适配体部分互补序列修饰的上转换纳米粒子竞争结合,荧光信号增强;而目标物Mucin-1和其适配体部分互补序列修饰的金纳米粒子竞争结合,拉曼信号减弱。将荧光信号与目标物AFP的浓度建立标准曲线,拉曼信号与目标物Mucin-1的浓度建立标准曲线,以此来定量检测癌症标志物甲胎蛋白及粘蛋白-1。
发明内容
本发明的目的是提供一种金-上转换纳米粒子三聚体的制备方法及其应用,其提供的新型的、简便的、灵敏的检测方法,把纳米材料作为一种新型探针,进行AFP和Mucin-1的超灵敏检测。
