The electrodes can be modified with a specific membrane for the selective detection of histamineintegrated with a separation device to perform high selective detection of multi-analytes.
Market Potential Analysis 本團隊以簡單、快速的方法製作出便宜化與可拋式磷酸銅複合電極,以該技術為基礎開發出可量測20種α-胺基酸與生物胺的免標定式感測器。該感測器可藉由表面修飾技術,提升組織胺的選擇性,可以非酵素之電化學檢測技術直接量測生物樣本中的組織胺濃度。配合手持式電化學分析儀,可類似血糖IVD檢測裝置達到單次性可拋式的量測,適合非訓練人員對食品鮮度品質鑑定。此外,該薄膜型磷酸銅複合材料感測試片,利於與流動式注入分析系統整合,可發展出兼顧精準、高通量與低價的分析平台,相當適合大型食品加工進出口商或是飼料製造商建立高通量的自我管理品質監控實驗室。此可拋式磷酸銅複合電極試片已驗證可與高效能液相層析儀或是可攜式紙基層析晶片整合,可利於現有商業化儀器直接進行多工與高選擇性的胺基酸分析,可當作官方實驗室或醫院確認血液內胺基酸失衡的檢測利器。 該高電催化性磷酸電極可減少樣本前處理程序,加速檢測效率。此磷酸銅複合電極的製作與量測技術,可取代現有酵素型試紙或是免疫抗體反應試片的不穩定性與價格昂貴等缺點,可被廣泛應用於食品安全、魚肉鮮度、飼料品質或是臨床藥物敏感性(組織胺釋出)測試…等需求。
Industrial Applicability The sensor can be used for the determination of bioamines in fishes, meat products, cheeseswines to estimate the effect of productionstorage conditions on the food freshness.
