Fe 3O 4@ polypyrrole core-shell nanohybrid for efficient DNA retrieval

Abstract

Core-shell nanohybrid, Fe 3O 4@PPY, which consists of superparamagnetic Fe 3O 4 core and DNA attractive polypyrrole, was successfully synthesized through the free radical polymerization. The DNA retrieval efficacy of the nanohybrid was found to be very high in DNA solution with low concentration (∼33% uptake in 100 μM).
