Research efforts are increasingly focused on the development of portable devices for the on‐site evaluation of pesticide residues in food. In article 1900076, Jimena S. Tuninetti and co‐workers develop a chemi‐impedimetric sensor of imazalil using metal–organic frameworks (MOFs) incorporated into a conductive PEDOT composite film. The high affinity of the pesticide for the MOF crystallites allows for outstanding sensitivity to imazalil in the range of 15 ppb to 1 ppm.

用于阻抗式农药传感器的MOF @ PEDOT复合膜（全球挑战2/2020）

研究工作越来越集中在便携式设备的开发上，该设备用于现场评估食品中的农药残留。在1900076条中，Jimena S. Tuninetti及其同事使用结合在导电PEDOT复合膜中的金属有机骨架（MOF）开发了咪唑的化学阻抗传感器。农药对MOF晶体的高亲和力使其对咪唑的突出敏感性达到15 ppb至1 ppm。
