Nanometric Micelles for Drug Delivery and Catalysis2022.05.04 15:03 - Katarzyna Kuźniar
Medicine has been a field where nanotechnologies have shown great promise for diagnosis and drug delivery applications. The challenge of nanomedicine consists in carrying active molecules through the different biological barriers and reaching specific targets in an efficient and non-toxic way. With the advent of nanotechnologies, different carrier systems are now available. However, the development of small biocompatible carriers with high loading capacity, extended circulation time, and favorable biodistribution has several unanswered issues.
This talk will give an overview of our findings regarding polymerized micelles obtained from original diacetylene-containing amphiphiles. Their chemical synthesis, assembly and characterization will be presented as well as some biomedical applications such as tumor imaging and drug delivery.
Micelles were also valorized by our group for synthetic applications such as the promotion of the Huisgen 1,3-dipolar cycloaddition (“click” reaction) between alkynes derivatives and azido compounds in water. Some examples illustrating the potential of the micelles in the catalysis of the “click” reaction will be presented.
