DNA-Based Enzyme Reactors and Systems
2016
During recent years, the possibility to create custom biocompatible nanoshapes using DNA as a building material has rapidly emerged. Further, these rationally designed DNA structures could be exploited in positioning pivotal molecules, such as enzymes, with nanometer-level precision. This feature could be used in the fabrication of artificial biochemical machinery that is able to mimic the complex reactions found in living cells. Currently, DNA-enzyme hybrids can be used to control (multi-enzyme) cascade reactions and to regulate the enzyme functions and the reaction pathways. Moreover, sophisticated DNA structures can be utilized in encapsulating active enzymes and delivering the molecular…
Unraveling the interaction between doxorubicin and DNA origami nanostructures for customizable chemotherapeutic drug release
2021
We thank Dr H. Häkkänen for technical assistance and S. Julin for the 24HB DNA origami design. We acknowledge the provision of facilities and technical support by Aalto University Bioeconomy Facilities and OtaNano – Nanomicroscopy Center (Aalto-NMC). The research was carried out under the Academy of Finland Centres of Excellence Programme (2014–2019).

Here and for the first time, we show that the organometallic compound [Ru(&eta
Recombinant nanocapsid for targeted theranostic delivery
2017
Developments in diagnostic and therapeutic delivery are trending towards molecular level targeting with nano-platforms. Targeted delivery reduces generalized distribution by localizing diagnostic and/or therapeutic (theranostic) molecules to an intended target site. The first section of this thesis proposes Hepatitis E Virus (HEV) nanocapsids as a vector to stabilize and target theranostic delivery. Derived from the capsid protein of HEV, a feco-orally transmitted virus, HEV-like particles self-assemble in to non-infectious, nanocapsids that can withstand harsh protease and pH conditions in the mucosal system. The flexible nanocapsid surface protrusion domain is amenable to substantial modi…
