Zernike Seminar - Olga Koshkina - Tailor-Made Nanocarriers: from the Bench to Clinic

When:Mo 08-02-2021 14:30 - 15:30

Personalized therapies with theranostic nanocarriers promise to solve major public health problems. Equipped with a therapeutic and diagnostic function, these nanocarriers transport the therapeutics precisely to the site of disease and provide imaging contrast for diagnostics. Yet, no theranostic nanocarrier has reached the clinical use. My overall goal is to develop efficient polymeric nanocarriers for imaging and therapy. To achieve this goal, it is crucial to produce functional nanoparticles, understand their physicochemical properties, and to correlate them to function. In my presentation, I am going to address several aspects that are important for the development of nanocarriers, including:

1) Surface functionalization of nanoparticles. I will focus on the modification with the thermoresponsive poly(2-oxazolines) that enables control of the interactions between nanoparticles and serum using temperature as a stimulus. 1

2) Development of nanoparticles loaded with perfluorocarbons for multimodal imaging with 19F Magnetic Resonance Imaging and ultrasound.2,3 Here, I will show, how polymeric nanoparticles that display an unusual fractal structure can overcome several challenges, including the long organ retention.

3) Scaling up the production of nanoparticles for clinical use with microfluidics.4

4) Production of anisotropic supraparticles via the evaporation-driven assembly of colloidal building blocks.5

Overall, my talk will cover several stages in the development of functional nanoparticles from the bench to clinic, highlighting the physicochemical aspects that govern the function of nanocarriers.
