摘要：
The mechanistic role of template in the enzymatic synthesis of conducting polyaniline has been investigated using micelles and DNA as ionic templates. These studies show the existence and importance of a molecular local environment where the pH and charge density near the template molecule is different form that of the bulk solution. This local environment serves as a type of "nanoreactor" that ultimately controls the type of polyaniline that is produced enzymatically. When DNA is used as the template, an electro-responsive polyaniline/DNA complex is formed where the conformation of the DNA may be controlled through the electronic state of the polyaniline.
