ibiTea - A Scientific Get Togheter - Bioprinting and Tissue Engineering

We are pleased to invite you to 10th ibiTea meeting. Join us for an informative webinar presented by leading scientists in the field of Bioprinting. Learn more about different printing techniques, their applications in tissue engineering and organ-on-chip solutions, and the future potential of new approaches in this fascinating research field.

Andreas Blaeser and Bastian Kreidl will discuss their new ideas and approaches in Bioprinting.

3D-Bioprinting Meets Microfluidics – A Versatile Approach for the Automated Bioproduction of Vascularized Organ-on-a-Chip Systems

Organ-on-a-chip systems (OOCs) are in vitro tissue models of complex organs, such as the heart, liver, or kidney, which can be cultivated dynamically on microfluidic carriers. In contrast to animal experiments, OOCs allow new active substances or toxins to be tested on humanized samples. This improves the clinical translation of obtained research results. In addition, OOCs represent a sustainable alternative to animal experiments. Furthermore, they can be personalized to enable tailored patient therapy.

However, due to the labor intensive biofabrication of OOCs, their industrial use is still limited. To overcome these hurdles, the group merges 3D-bioprinting technology and laboratory robotics to enable a fully automated OOC bioproduction process and thereby increase their industrial applicability.

Femtosecond Bioprinting of Micro-Organisms

Femtosecond Bioprinting (FsB) is a laser-assisted printing technique, originated from Laser Induced Forward Transfer (LIFT). It enables the precise deposition of various generic biomaterials and the selection, isolation, and transfer of micro-organisms while maintaining high survival rates of up to 98,5 %.

In FsB, near-infrared femtosecond laser pulses are tightly focused into a non-/weakly absorbing bioink. This leads to a series of events, generating a thin laminar bioink jet propagating towards a target substrate. Coupled with controllable XYZ-stages, this enables the creation of bioink and/or micro-organism patterns, even down to single cell resolution.

We invite you to participate in the meeting!
