据外媒报道,来自大阪城市大学的一组研究人员通过跟国际合作伙伴合作利用量子技术创造出了一种可靠且精准的、基于显微镜温度计。 这个温度计非常精确,它可以测量微观动物的温度。该技术可以检测温度依赖性的量子自旋和荧光纳米金刚石。

量子传感技术利用了极其脆弱的量子系统对周围环境的敏感性。七年前,研究人员使用了一种类似的技术来量化培养细胞内的温度。这项新技术可以感知积极参与生物过程的热量和温度。

为了打造这种设备,研究小组使用聚合物结构装饰纳米金刚石的表面并将其注射到秀丽隐杆线虫体内,线虫是生物学中最流行的模型动物之一。研究人员想要了解蠕虫的基本健康温度。在纳米金刚石进入生物体内之后其移动得非常快。不过即便如此,量子监控算法仍能跟踪纳米金刚石并稳定地测量温度。

研究人员通过药物治疗刺激线粒体,他们让蠕虫体内发烧,而量子温度计成功地观察到了这一温度的上升。研究人员表示,看到量子技术在活体动物身上很好地工作令人感到兴奋。

一位研究人员表示,研究小组从不相信小于一毫米的小蠕虫会偏离正常温度继而发展成发烧。研究人员称,他们的测试结果是一个重要的里程碑,它将指导量子传感跟生物学相关的未来方向。研究人员将在未来继续完善和改进他们的技术。
