Summary:	量子點的螢光穩定性常被應用於生物學上做為標示使用，而取代了傳統的螢光染劑。抗體包覆量子點外層去標定抗原的方式與使用分子拓印技術製備類似抗體位子去吸附目標分子的方式相似，因此，利用分子拓印高分子包覆量子點亦可具有模版孔洞與選擇性，本研究以聚乙烯-乙烯醇（poly(ethylene-co-vinyl alcohol), EVAL）混合不同放射波長的量子點加入沉澱槽，利用相轉換的方式進行快速製備分子拓印高分子複合奈米微粒，進行型態、再吸附性質分析，並藉由量子點的螢光穩定性變化檢測尿液中肌酸酐、白蛋白、溶菌酶分子濃度，與醫院生化檢測濃度做準確率之比較。 The high stability of quantum dots (QDots) with photoluminescence has led to their increase use as imaging approaches in biological systems to replace conventional fluorescence labels. The antibodies are generally coated on the surface of QDots to the targeting site, and molecular imprinting polymers are designed to mimic the antibodies. Hence, quantum dots can be incorporated into molecularly imprinted polymers, which provide shape and selectivity, and then respond to template rebinding by emitting quenched photoluminescence. In this study, poly(ethylene-co-ethylene alcohol) creatinine-, albumin- and lysozyme-imprinted polymers nanoparticles are synthesized via phase inversion of poly(ethylene-co-ethylene alcohol) with various ethylene mole ratios when target molecules and hydrophobic quantum dots are mixed within the polymer solution. Finally, those particles were prepared for the detection of creatinine, human serum albumin and lysozyme in real sample (urine) and compared with commercial ARCHITECT ci 8200 system.Keywords: poly(ethylene-co-ethylene alcohol); creatinine; albumin; lysozyme; molecular imprinting; urine.
