Treatment of cells for cell-based therapies is a newer form of therapy in which cells are injected in
patient in order to prevent or treat illnesses. A well-known example is usage of a cancer patient’
own immune cells to attack the tumor cells. Vapour nanobubble (VNB) photoporation is
particularly promising for ex vivo preparation of cells for cell-based therapies as it typically
provides high efficiency, high throughput and low toxicity. It is based on usage of plasmonic
nanoparticles, such as gold nanoparticle (AuNP), which can form explosive nanobubbles upon
pulsed laser irradiation. Those tiny explosions can form small pores in cell membranes, allowing
functional molecules and nanoparticles to enter into cells. However, translation of VNB
photoporation to clinical applications is hindered by the fact that current procedure depends on
AuNP that is in close contact with cell membrane. Therefore, in this project we will investigate the
possibility to perform VNB photoporation of cells without AuNP being in contact with cells. Fluid
and molecular dynamics simulations will be used to investigate the conditions at which contactfree
photoporation of cell membrane can be achieved. Next it will be investigated by simulations
and experiments how explosive VNB may influence fluid flow in a microfluidic channel. The final
step is to design microfluidic devices in which the distance between cells and AuNP can be
controlled so as to achieve contact-free VNB photoporation of cells.
