Theranostic nanosystems

The primary advantage of theranostics is that they are not limited to therapy or imaging, but allow for combinations, to give coincident diagnostic information plus delivery of therapeutics. Nanoscopic objects provide domains for high capacities of therapeutic loading and sites for labeling, while also having high surface areas for the presentation of targeting ligands. Cancer is one our societys most common diseases, increasing in prevalence as our society ages. To combat and ensure better treatment and diagnostic tools the medical community needs both better chemotherapeutics as well as smart and specific ways of delivering them to the patients. This interdisciplinary project's overall aim in to develop new therapeutic devices for delivery and diagnostic imaging of breast cancer. These nanodevices are termed "theranostics", a combination of therapy and diagnostics in the same device, to treat and image efficacy with one single tool. Theranostic devices represent the most recent development within the area of nanomedicine and have high future potential in being the primary tool for personalized medicine. The novelty of this work lies in how we can combine these features in a novel way utilizing properties of the polymer systems that have not been investigated previously.

This work is conducted in collaboration with Prof Eva Malmström at The Royal Institute of Technology (KTH).
