    About Yusuke

    Yusuke Sakai, PhD is one of the youngest awardees of POLONEZ programme, a regional Marie Curie Fellowship co-funded by Polish National Science Centre (NCN) and Horizon 2020. Since 2016 he has been running his own project as a semi-independent postdoc researcher in the group of Prof. Jonathan Heddle at the Malopolska Centre of Biotechnology, Jagiellonian University in Krakow. Before moving from Japan to Poland, he investigated the mechanism of tRNA modification involved in bacterial decoding system and took a doctorate at the Department of Chemistry and Biotechnology, the Graduate School of Engineering, the University of Tokyo. At MCB, he expanded his field to DNA nanotechnology and is developing DNA based nanorobot aiming at smart drug delivery. After the POLONEZ programme, he is drawing a plan to bridge DNA nanotechnology and molecular biology by e.g. offering useful DNA/RNA based nano-tools those enable to elucidate challenging issues in basic science.

    About the Project

    DNA is not only the blueprint of genetic information as all knows, but also can be material which has self-assembling nature. Once designing and synthesising a set of short oligo DNAs, a long scaffold DNA is folded to form multiple pattern of crossovering, forming single defined shape. This method, called DNA origami methodology has enabled us to design arbitrary shape of nanostructure efficiently. Here we are developing DNA origami based nanocapsule which can separate the hollow from surrounding. The structure can be connected or dissociated to each other, open and close by external signal, eventually have potential to be a component of novel and smart carrier for drug delivery.
