Recent work relevant to heavy metal determination by inhibition-enzyme electrochemical biosensors and by selected biomimetic sensors based on molecularly imprinted polymers has been reviewed. General features and peculiar aspects have been evidenced. The replace of biological component by artificial receptors promises higher selectivity and stability, while biosensors keep their capability of producing an integrated response directly related to biological toxicity of the samples.
本文综述了近期通过抑制酶电化学生物传感器以及基于分子印迹聚合物的特定仿生传感器测定重金属的相关工作。已阐明了其一般特征和独特方面。用人工受体取代生物成分有望实现更高的选择性和稳定性,而生物传感器仍保持其产生与样品生物毒性直接相关的综合响应的能力。
