Facile Preparation of a Bacteria Imprinted Artificial Receptor for Highly Selective Bacterial Recognition and Label-Free Impedimetric Detection

The effective identification and quantification of pathogenic bacteria is essential for addressing serious public health issues. Here, we demonstrate a simple and universal impedimetric sensor for highly selective and sensitive detection of pathogenic bacteria based on the recognition by a bacteria-imprinted polypyrrole (BIP) film. The BIP film was facilely prepared via one-step electro-polymerization followed by in situ removal of the bacterial...
