Research focus

Intracellular delivery of exogenous molecules into cells has become a crucial step for many therapeutic applications and fundamental biological research. However, to reach the cytosolic compartment, the cell membrane barriers need to be overcome, which is considered a major hurdle for biological macromolecules often exhibiting unfavorable characteristics like size, charge and stability. Over the years, several strategies have been developed ranging from nanocarrier-mediated to membrane disruption-based methods. Especially for in vitro and ex vivo settings, physical delivery methods are most interesting as they present fast, efficient and safe delivery featuring a broad applicability.
One of these emerging membrane disruption-based techniques is vapor nanobubble (VNB)-mediated photoporation, which makes use of photothermal nanoparticles and pulsed laser light. More specifically, upon laser irradiation the nanoparticles rapidly heat up leading to the evaporation of their surrounding water. Fast expanding VNBs emerge around the nanoparticles that, upon their collapse, impose significant mechanical stress on the cell membrane leading to transient pore formation. Interestingly, the laser diameter can be fine-tuned to such extent that highly-selective single-cell delivery is possible as well.
The research project of Jana employs VNB-mediated photoporation for several applications. More specifically, this technique is used as foundation to answer research questions in the field of cancer biology and extracellular vesicles. Secondly, VNB-mediated photoporation is explored for its applicability in the treatment of melanoma cancers.
