A2780 ovarian carcinoma cells were kindly donated by Dr. Darren Griffith, Department of Pharmaceutical and Medicinal Chemistry, Royal College of Surgeons in Ireland. Funding derived from the Health Research Board in Ireland under grant number PHD/2007/11 and from Enterprise Ireland under project number CFTD/2009/0127. E. R-H. is supported by the European Union FP7 under a Marie Curie Intra-European Fellowship for Career Development (project NanoSmart). † Dr. A. López-Noriega and Dr. C. L.

A novel drug delivery system, enabling an in situ, thermally triggered drug release is described, consisting of an injectable thermoresponsive chitosan hydrogel containing doxorubicin-loaded thermosensitive liposomes. The design, fabrication, characterization, and an assessment of in vitro bioactivity of this formulation is detailed. Combining on-demand drug delivery with in situ gelation results in a promising candidate for local chemotherapy.
