領(lǐng)域：多倫多大學(xué)士嘉堡分?；瘜W(xué)系助理教授張曉安稱，在活生物系統(tǒng)中實(shí)時(shí)檢測(cè)pH值，對(duì)于探測(cè)和理解pH值失衡導(dǎo)致的相關(guān)疾病至關(guān)重要。如低pH值與囊性纖維化、局部缺血以及癌癥的病理狀況密切相關(guān)。pH值信號(hào)可用于診斷疾病及監(jiān)測(cè)效果，了解人體組織內(nèi)的pH值在何時(shí)何地發(fā)生顯著變化是非常重要的。因此，迫切需要找到一種可進(jìn)行深入、的探查，同時(shí)又確保不入侵組織的新方法。張曉安團(tuán)隊(duì)使用核磁共振光譜技術(shù)開(kāi)發(fā)的微型傳感器，可以非侵入方式在原子水平對(duì)分子進(jìn)行非常詳細(xì)的觀察。
