台大生物產業機電工程學系碩士生賴昱廷發展農藥殘留檢驗試紙技術,不僅方便快速,更具備與手機結合進行即時檢測的潛力,今年11月研究成果榮登《micromachines》科學期刊。

    生機系表示,這項技術是由賴昱廷創意發想與執行,並與生機系教授盧彥和昆蟲系教授許如君的團隊進行跨領域合作。此項技術是藉由ELISA反應原理,從試紙上生物標誌與檢體中抗原結合時造成的顏色變化,來判斷農藥殘留量。由於紙張具有易取得、低成本、具生物相容性的優點,同時利用紙張的毛細作用,可以不須外在壓力即能直接運送流體。而賴昱廷所發展的關鍵技術,可以控制流體在紙張上的流動方向、流速、反應時間等,解決了利用試紙為檢測基材時,無法使用於較複雜處理步驟的生化反應的限制,同時具有與手機結合進行即時檢測的潛力。

The Department of Biomechatronics Engineering has developed a testing paper for the detection of residual pesticides. The related research outcomes were published in the journal Micromachines on November 2019. This technology was creatively developed and implemented by the master’s student Yu-Ting Lai, and cross-disciplinary cooperation with the team of Professor Yan Lu of the Department of Biomechatronics Engineering and Professor Ru-Jun Xu of the Department of Entomology.This technology uses the principle of ELISA reactions to determine the amount of residual pesticide based on the color change caused by the combination of the biomarker on the testing paper with the antigen in the sample.The developed testing paper has the advantages of easy availability, low cost, and biocompatibility. The capillary action of the paper can directly transport fluids without external pressure, which overcomes the limitations of previous testing paper that required complicated processing steps. Furthermore, the newly developed technology can be combined with mobile phones for real-time pesticide detection.
