摘要：

Poly(3-hydroxybenzoic acid) (poly(3-HBA)) was produced by the electropolymerization of 3-hydroxybenzoic acid on graphite electrode and characterized by spectroscopic and electrochemical methods. This polymer was used for incorporation of an oligonucleotide as well as detection of the complementary target, by differential pulse voltammetry. The results suggest that graphite electrodes recovered with poly(3-HBA) can be an efficient matrix for immobilization of oligonucleotides in biosensors for DNA.
