As a part of a pan-European task force in the field, our team has developed a series of innovative theranostic systems which proven to be excellent agents in cancer imaging and therapeutics in vivo. Specifically, exploiting the quintessence of nanotechnology, i.e., the self-assembling process of small, amphiphilic molecules, in the last decade we created a series of high-performance, non-toxic nanosized micelles that, depending on the specific chemistry, are able to (e.g.):
• encapsulate anticancer drugs with high loading capacity, enhance drug potency and combat drug resistance by promoting cellular uptake whilst decreasing drug efflux;
• perform specific and effective gene silencing via targeted small interfering RNA (siRNA) delivery;
• provide PET images with significantly superior imaging quality relating to sensitivity, specificity and accuracy when compared to the clinical standard [18F]FDG.
In this contribution we will report in details the full pathways leading to these three types of nanosystems, from their computer assisted molecular design to their in vivo performance.
