Programme

Unfurtunately the monastery Irsee has been closed by the Bavarian government due to the corona virus.

Therefore we have decided to offer the conference as a web conference only.

In those unpredictable times, protecting our participants’ health has the highest priority for us!

The scientific exchange must not come to a complete standstill and we believe that with this web solution we have found a way to keep the scientific community going.

In order to participate in the livestream of the conference as easy as possible and to give your presentation, we recommend the use of the web browsers Google Chrome or Microsoft Edge.

Here you can find detailed instructions for using the livestream.

As a participant of the Bioinspired 2020 you have received an e-mail containing the login data for the web conference.

The login data for the sessions are provided daily.

In order to allow all conference participants access to the posters, we ask you to upload your poster by login on the conference homepage and clicking on the button "My Submission" in the upper right corner of the conference homepage. Then select the submission to which you want to upload the poster and upload the poster at the bottom of the page.

Furthermore we would like to ask all poster authors to prepare 4 PowerPoint slides to present your poster to the audience.
Please also include your contact details on the digital poster to allow participants to reach you with questions.

Please note that your poster will be pictured publically.

As poster author you can upload your poster similar to the way you submitted your abstract.
Click on "My Submissions" in the upper right corner at the homepage.

Poster documents can be found by opening the respective abstract in the online programme.
If a poster document has already been uploaded for the abstract, it can then be opened and downloaded.

Please note that your poster will be pictured publically.

You can ask your questions via chat already during the presentations!
Please use for this the Q&A (F&A) button!

For further scientific exchange we implemented a discussion forum on the homepage of the DGM.
Please visit discussion.dgm.de and use your DGM or Bioinspired user credentials to login.

Special Poster Session Biofabrication

Improved Printability of a Novel Thermoresponsive Hydrogel Bioink by Nanoclay Addition

Tuesday (17.03.2020)
18:04 - 18:07

As a promising biofabrication technology, extrusion-based bioprinting has gained significant attention in the last decade. However, materials that offer an "ideal" combination of printability, shape fidelity, suitable crosslinking mechanism and cytocompatibility are rare. Poly(2-oxazoline)s based biomaterials have been discussed as a potential alternative to the more established polyethylene glycol biomaterial system, due to their facile synthesis, physicochemical versatility and good cyto-/biocompatibility. Although a few different POx-based block copolymers that undergo thermogelation were described recently, it's not possible to print the real 3D constructs at this point. Herein, we describe a hybrid system of nanoclay and a thermoresponsive hydrogel as a novel bioink, and discuss its critical properties relevant for extrusion-based bioprinting, including viscoelastic properties, printability and cytocompatibility. The hybrid hydrogel retains its thermogelling properties but is strengthened by the added clay (G’= 5 kPa). Importantly, the shear-thinning character is further enhanced, which, in combination with very rapid structure recovery (~2 s) is highly beneficial for 3D printing. Accordingly, various 3D patterns are printed with high-resolution and greatly enhanced shape fidelity compared to the bioink without added clay. Results from in vitro cytocompatibility and cell-laden printing suggests its feasibility for cell printing. Overall, a novel ideal bioink is proposed in this study which will expand the options available to researchers in 3D bioprinting biofabrication, and lead to more complex and biomimetic structures in the future. In addition, it may provide a new promising material platform for controlled delivery and release, sacrificial material templates in fabrication of microfluidic devices and thermoresponsive self-protection.
