title: Fast pH-assisted functionalization of silver nanoparticles with monothiolated DNA.
abstract: Attaching monothiolated DNA to silver nanoparticles has been achieved at pH 3.0 in 30 minutes and difficulties associated with DNA attachment to AgNPs at neutral pH have been revealed by studying DNA adsorption kinetics.
