Research on nanothermometry continues (new paper from the team)

By -

Prof. Ruslan Dmitriev and PhD candidate Angela Debruyne collaborated with TU Graz (Prof. S. Borisov) and University of Tubingen on the design of new type of the nanothermometer, based on organic Zr complexes and exhibiting long emission decay times. These materials open a new framework for microsecond-range emitting temperature-sensitive materials, providing better resolution and potential applications in imaging temperature gradients in multicellular spheroids, as we have demonstrated in the study.

The research has been published in Advanced Optical Materials journal.

Affordable microscopy of spheroid oxygenation (video protocol)

Our lab has published a new protocol paper, this time with the video, in the Journal of Visualized Experiments (JoVE)! In this research method paper, we report the use of red/ near-infrared emitting biocompatible nanosensors to monitor oxygenation of the live multicellular spheroids (made of one or more cell types), together with the tracers of cell death. While this methodology is typically available only for users with 'high-end' PLIM microscopes and alike, we show that using of ratiometric readout with the red and near infrared emitting fluorescent nanosensors makes this possible on broadly available 'widefield' fluorescence microscope platforms. This method helps comparing oxygenation of spheroids, assessing this in a long-term and kinetic assays, comparing their variability and viability, essential in follow-up 3D printing applications. This is the first article in our collection ' Quantitative live cell imaging of 3D models' , guest-edited together with

Together with Prof. Margarida Barroso (Albany Medical College), we guest edit a collection of video protocols, hosted by the Journal of Visualised Experiments ( JoVE ), and  dedicated to the quantitative live cell imaging in 3D .  We expect bringing together some leaders and innovators in various aspects of the quantitative live fluorescence microscopies applied to ex vivo animal models, organoids and 3D engineered tissue blocks. The collection, which just has been started, can be assessed here .
