    Rüegg, Curzio ; Reis, Corine ; Rafiee, Sarah ; Rodriguez-Lorenzoa, Laura ; List, Jonathan ; Rothen-Rutishauser, Barbara ; Mayer, Michael ; Petri-Fink, Alke

    In: CHIMIA International Journal for Chemistry, 2019, vol. 73, no. 1, p. 63–68

    The main cause of cancer-related death is due to cancer cell spreading and formation of secondary tumors in distant organs, the so-called metastases. Metastatic cancer cells are detectable in the blood of cancer patients as circulating tumor cells (CTC) and may be exploited for prognostic and monitoring purposes, including in breast cancer. Due to their very low frequency, however, their...

    A rational and iterative process for targeted nanoparticle design and validation

    Rodriguez-Lorenzo, Laura ; D.Rafiee, Sarah ; Reis, Corine ; Milosevic, Ana ; L.Moore, Thomas ; Balog, Sandor ; Rothen-Rutishauser, Barbara ; Ruegg, Curzio ; Petri-Fink, Alke

    In: Colloids and Surfaces B: Biointerfaces, 2018, vol. 171, p. 579–589

    The lack of understanding of fundamental nano-bio interactions, and difficulties in designing particles stable in complex biological environments are major limitations to their translation into biomedical clinical applications. Here we present a multi- parametric approach to fully characterize targeted nanoparticles, and emphasizes the significant effect that each detail in the synthetic...
