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.
