    The lung represents the primary entry route for airborne particles into the human body. Most studies addressed possible adverse effects using single (nano)particles, but aerosolic nanoparticles (NPs) tend to aggregate and form structures of several hundreds nm in diameter, changing the physico-chemical properties and interaction with cells. Our aim was to investigate how aggregation might...

    A novel sample holder for 4D live cell imaging to study cellular dynamics in complex 3D tissue cultures

    Septiadi, Dedy ; Bourquin, Joel ; Durantie, Estelle ; Petri-Fink, Alke ; Rothen-Rutishauser, Barbara

    In: Scientific Reports, 2018, vol. 8, no. 1, p. 9861

    Three dimensional (3D) co-cultures to mimic cellular dynamics have brought significant impacts in tissue engineering approaches for biomedical research. Herein, we present a novel sample holder combined with time-lapse fluorescence imaging technique, referred as 4D live cell imaging, allowing direct visualization of various cells up to 24 hours. We further extended our approach to monitor...
