2019年8月，我校莊松林院士團隊超精密光學制造課題組張大偉教授、戴博副教授、鄭璐璐老師、萬新軍老師、焦子傲同學的最新成果論文《Colour compound lenses for a portable fluorescence microscope》在國際光學頂尖期刊《Light: Science & Applications》（影響因子14.098）上發(fā)表。戴博、焦子傲和鄭璐璐為第一作者，張大偉和Tony Jun Huang為通訊作者。
該成果與美國杜克大學、美國戴頓大學、復旦大學、復旦大學附屬腫瘤醫(yī)院合作，主要研制了一種彩色液滴透鏡器件，并實現(xiàn)了基于智能手機的便攜式熒光顯微成像應用。
熒光顯微成像技術是實現(xiàn)生物樣品觀測與生化指標檢測的重要方式之一，傳統(tǒng)的熒光顯微檢測只能在實驗室利用昂貴的熒光顯微鏡實現(xiàn)，為了解決設備昂貴、攜帶不便等問題，研究人員受到“葡萄酒濾光現(xiàn)象”的啟發(fā)，利用蒽醌染料對高分子聚合物和高折射率硅油進行染色，通過光流控技術，創(chuàng)新制作了多款彩色復合液滴透鏡，該透鏡可同時實現(xiàn)圖像放大及光學濾波的功能。并且，通過將透鏡安裝于手機上，實現(xiàn)了細胞觀察、細胞計數(shù)、腫瘤組織切片熒光檢測、質粒轉染表達檢測、細胞凋亡超氧化物生成檢測等應用，得到了同行專家的高度認可。該研究成果可廣泛用于生物醫(yī)學即時檢測的應用環(huán)境，為醫(yī)療資源匱乏地區(qū)以及戰(zhàn)場醫(yī)學提供有效技術保障。
該研究項目得到了國家重點研發(fā)計劃、國家自然科學基金、上海市科學技術委員會項目的資助。

Editorial Summary
Fluorescence microscopy: Smartphone solutions for seeing cells
A method of turning a smartphone into a fluorescence microscope, developed by researchers in the US and China, enables complex biomedical analyses to be performed rapidly and inexpensively. Conventional fluorescence microscopes are vital for detecting specific cell types and proteins, but are bulky and inconvenient for point-of-care diagnoses. Tony Jun Huang at Duke University, Dawei Zhang at USST and co-workers used liquid polymers to create miniature lenses comprising two droplets, one inside the other, dyed with colored solvents. The lenses, which are compatible with several different smartphone cameras, allowed the researchers not only to observe and count cells, but also to monitor the expression of fluorescently-tagged genes, and to distinguish between normal tissue and tumors. This ingenious use of easily-accessible and affordable smartphone technology will lead to better on-site personalized medicine, especially for developing countries.
