Poly(anilineboronic acid) (PABA) nanofibers with U‐shaped and ring‐shaped morphologies have been synthesized successfully by chemical polymerization of 3‐aminophenylboronic acid (APBA) in the presence of cetyltrimethylammonium bromide (CTAB) and NaF. The morphologies and sizes of PABA nanofibers can be controlled by adjusting the synthetic parameters, such as the concentrations of CTAB and APBA. The U‐shaped PABA nanofibers exhibit excellent electrochemical redox activity and high sensitive detection of D ‐glucose in phosphate‐buffered saline stock solution (pH 7.4) because of their high effective surface area as well as the high density of boronic acid groups.
