Using MR Imaging to track the distribution and delivery of cargo from liposomes
August 2019
Light-responsive drug delivery systems have been around for years now. But how do we know if they reach their destination in human body? And if they do, how do we know if we deliver enough light to release the drug?

Purines substituted in 6 position form an important class of bioactive compounds. While these structures seem like perfect candidates for azologisation in photopharmacological approach, they were elusive due to the low reactivity of the 6-amino group in purines. Now Dusan shows in our new paper how a serendipitous discovery lead to a general synthetic method that conveniently yields the title compounds in good yields. And yes, they also switch with green light!

Just in the news: Ben received the Nobel Prize in Chemistry! We are honored to be able to work with such esteemed scientist. What a day for all the group! See us cheering here
Red-shifted azobenzenes made easy
September 2016
Tetra-ortho-substituted azobenzenes, with red-shifted spectra, can be operated using visible and NIR light. They were introduced in seminal papers by the groups of Prof. Woolley (Toronto) and Prof. Hecht (Berlin). We believe that these compounds are the future of photopharmacology, since low energy photons penetrate deeper into the tissues and are scattered less. However, until now their synthesis was very challenging. In our new paper, Mickel shows an easy way to synthesize tetra-ortho-substituted azobenzenes with high yields!
Photoactivated Chemotherapy
September 2016
