  This research maps the knowledge translation process for two different types
of nanotechnologies applied to cancer: liposomes and metallic nanostructures
(MNs). We performed a structural analysis of citation networks and text mining
supported in controlled vocabularies. In the case of liposomes, our results
identify subnetworks (invisible colleges) associated with different therapeutic
strategies: nanopharmacology, hyperthermia, and gene therapy. Only in the
pharmacological strategy was an organized knowledge translation process
identified, which, however, is monopolized by the liposomal doxorubicins. In
the case of MNs, subnetworks are not differentiated by the type of therapeutic
strategy, and the content of the documents is still basic research. Research on
MNs is highly focused on developing a combination of molecular imaging and
photothermal therapy.
