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

Fiber reinforced hydrogels – a new platform technology in biofabrication

Tuesday (17.03.2020)
17:52 - 17:55

Hydrogels display highly attractive properties for their use in the field of biofabrication and tissue engineering. With a water content above 80%, they form 3D network structures that can resemble parts of the extracellular matrix of native tissue and are therefore predestined to be used as bioinks in 3D printing processes including living cells. They can be prepared from various polymers, either synthetic or biological, to match the requirements of the targeted tissue that must be replaced. To enable sufficient resolutions in the printing process, high polymer concentrations are generally required resulting in increased shear forces on the incorporated cells upon printing. Unfortunately, this is commonly known to be at the expense of cell viability. To simultaneously enable good printing resolutions and maintain high cell viability, it is important to trigger the rheological properties of bioinks towards low internal shear forces upon-, and high shape fidelity after printing. Filler materials such as fibers and spheres provide a widely used strategy to change rheological properties of solutions and melts and can further be applied to reinforce matrix materials. In this work, we developed a systematic approach to adapt the flow behavior of bioinks upon printing and increase the mechanical performance of the printed constructs. Electrospinning was applied to produce micro-fiber fragments made from poly-ε-caprolactone (PCL), providing good mechanical properties and biodegradability. Thermo-responsive gelatin methacrylate (GelMa) hydrogels were used as the matrix material promoting cell adhesion and proliferation. Pluronic was applied as an additional test system to systematically investigate the influence of fragment concentration in a shear thinning system. The resulting composite systems should provide adjustable rheological properties that can be triggered by particle size and filling density. This systematic study includes electrospinning of PCL fiber fragments and SEM analysis thereof, surface modification of PCL particles by plasma treatment and oscillatory rheology to determine the effects of size, concentration and surface modification on the rheological properties of the resulting composite hydrogels.
