DESCRIPTION:Prof. Henrik Birkedal\, University of Copenhagen\, Denmark\nBi
 ology makes a wealth of advanced functional materials such as bone\, that 
 is stiff yet tough\, and blue mussel byssus that possesses abilities for u
 nderwater adhesion and self-healing. We investigate structural aspects of 
 biological materials\, bioinspired crystallization and bioinspired synthes
 is of soft materials. I will discuss our work on synthesis of bioinspired 
 responsive and self-healing materials. These are inspired by the self-heal
 ing coating of the blue mussel byssus that features proteins rich in catec
 hols\, through the amino acid DOPA\, and amines\, through the amino acid l
 ysine. By combining catechols\, catechol-analogues and plant polyphenols l
 ike tannic acid with synthetic amine containing polymers\, we have made mu
 ltiresponsive hydrogels whose properties depend on pH but also on the pres
 ence of trivalent metal ions. The catechol-metal coordination bonds are re
 versible\, which imbues the materials with rapid self-healing properties.\
 n\nBio: Henrik Birkedal is Associate Professor of chemistry at Aarhus Univ
 ersity\, Denmark. Following a master’s degree in chemistry from Universi
 ty of Copenhagen\, he obtained his PhD (with the Félicitations du Jury) f
 rom Université de Lausanne\, Switzerland in 2000. Following postdoctoral 
 stays in Lausanne and at University of California\, Santa Barbara\, he obt
 ained career grants from the Danish Research Councils for an assistant pro
 fessorship (2004) and associate professorship (2007) and transitioned into
  his current position in 2009.\nAt Aarhus University he is an integral par
 t of the interdisciplinary nanoscience center (iNANO) and part of the lead
 ership of the new cross-departmental Aarhus University Center for Integrat
 ed Materials Research (iMAT). His research focusses on biological and bioi
 nspired materials and combines high end characterization of materials stru
 cture by advanced synchrotron scattering\, diffraction and imaging studies
  with synthesis of bioinspired materials.\n
