Paula T. Hammond, PhD

Research Summary

The Hammond Laboratory uses electrostatics and self-assembly of polymers to create drug delivery systems that convey high degrees of spatial and temporal control and target cells of interest via multiple modes. They develop nanoparticles capable of delivering combination therapies that include siRNA, proteins, and small molecule drugs for ovarian cancer, as well as brain and other intractable cancers. Additional cancer applications include vaccine generation and delivery of immunostimulatory agents to the tumor microenvironment.    

The group’s signature layer-by-layer (LbL) nanoparticle delivery platform possesses great translational potential and several desirable features, including nanoscale size, combinatory therapeutics with high loading capacity, staged cargo release, enhanced stability in vivo, and tunable surfaces for targeting tumor or immune cells¬. These nanoparticles can incorporate therapeutics such as RNA, proteins, or small molecule drugs in nanolayers wrapping a charged colloidal core containing a chemotherapy such as doxorubicin or cisplatin. Further, the LbL platform can introduce different polymeric surface chemistries to target tumor tissues’ slight acidity, and present specific ligands that bind to known receptors highly expressed on the surfaces of several aggressive tumor cell types.

Hammond uses these same polymeric materials for drug releasing biomedical implants, growth factor and siRNA release for wound healing, bone regeneration, and vaccines.
