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.

Plenary Lecture

Colour Engineering: from nature to applications

Tuesday (17.03.2020)
08:50 - 09:30

The most brilliant colours in nature are obtained by structuring transparent materials on the scale of the wavelength of visible light. By controlling/designing the dimensions of such nanostructures, it is possible to achieve extremely intense colourations over the entire visible spectrum without using pigments or colorants. Colour obtained through structure, namely structural colour, is widespread in the animal and plant kingdom [1]. Such natural photonic nanostructures are generally synthesised in ambient conditions using a limited range of biopolymers. Given these limitations, an amazing range of optical structures exists: from very ordered photonic structures [2], to partially disordered [3], to completely random ones [4].

In this seminar, I will introduce some striking example of natural photonic structures [2-4] and review our recent advances to fabricate bio-mimetic photonic structures using the same material as nature. Developing biomimetic structures with cellulose enables us to fabricate novel photonic materials using low cost polymers in ambient conditions [6-7]. Importantly, it also allows us to understand the biological processes at work during the growth of these structures in plants.
