產(chǎn)品特點

1984 年，康奈爾大學 Lucas 教授S次提出了用緩慢振動的離子選擇性電極來無損測定凈離子流的想法，其主要理論是: 通過微電極測定溶液中生物組織兩個位置間的離子濃度梯度( 嚴格來說是電化學勢差) ，進而根據(jù)梯度計算目標離子的跨膜凈通量．之后，該理論在玉米根系 H+ 和 K+ 通量的化學計量測定上得到了S次實踐證明． 1995 年，美國伍茲霍爾研究所DY次將振動探針設備進行改造，使其具備離子流能力．與此同時，澳大利亞塔斯馬尼亞大學的 Newman在前人的理論基礎上對非損傷性微測技術進一步發(fā)展，發(fā)明出微電極離子流技術( MIFE，microelectrode ion flux estimation) ．
能準確地測定單細胞或完整植株特定微區(qū)細胞內(nèi)外離子濃度與流動方向．它具有高靈敏度、實時、非損傷性、分辨率高、噪值小等特點，而且還可以在電腦控制下不間斷測定與自動監(jiān)測，實現(xiàn)了生物體內(nèi)外離子或分子信息的同步測定．
