Welcome to BörnerLab

Research Overview

  1. Synthesis and design of functional hybrid polymers (bioconjugates)
  2. Bio-mimetic formation of structure and function in synthetic polymers (peptide-guided organization and structure based functions)
  3. Pseudopeptides and precision polymers for biomedical applications (integrated polymer systems for gene or drug delivery)
  4. Bio-functionalization of surfaces (bioactive polymer fibers, scaffolds and material interfaces; Bio-inspired adhesion segments in block copolymers, (bio)-functional coatings, crystal growth modifiers)

Objectives: Controlling interactions in synthetic polymers as precisely as in proteins would have a strong impact on polymer science. Advanced structural and functional control can lead to rational design of, integrated nano- and microstructures. To achieve this, properties of oligopeptides were exploited. By incorporating these as monodisperse segments into synthetic polymers we show how to program structure formation in polymers, control inorganic-organic interfaces in fiber composites, induce structure in biomacromolecules for biomedical applications and generate bioactive surfaces to control biological systems.

08.06.2015 - Generic biocombinatorial strategy to select tailor-made stabilizers for sol-gel nanoparticle synthesis.
New Paper in Small has been published.
 
A generic route toward de novo design of tailor-made stabilizers for sol-gel nanoparticle synthesis is described. By exploiting phage display biopanning to select stabilizers from large peptide libraries, a significantly larger chemical space (~ 109 different compounds) is explored, compared to commonly used knowledge-based or empiric strategies. The approach is demonstrated on the fluorolytic sol-gel synthesis of MgF2 nanoparticles from Mg(OCH3)2 precursors. Peptide sequences are selected, showing sequence-specific adsorption onto MgF2 particle surfaces.

19.03.2015 - Synthesis of conjugates combining macromolecular brushes and rigid macrocycles.

New Paper in Polymer has been published.
 
On the occasion of the 65th birthday of Krzysztof Matyjaszewski (Link) a synthesis route to a conjugate comprised of two macromolecular brushes and a central shape persistent macrocycle utilizing ATRP is presented. As a result of the properties of the combined structure elements a functional macromolecule is obtained that regulates accessibility to a central shape persistent macrocycle via reversible brush-coil transitions.

01.09.2014 - Revealing the impact of poly(ethylene oxide) blocks on enzyme activable coatings from peptide-polymer conjugates
New Paper in European Polymer Journal has been published.
 
Peptide-polymer conjugates composed of a poly(ethylene oxide) (PEO) block and a precursor segment from mussel foot protein-1 (mefp-1) are enzymatically oxidized by tyrosinase. A functional transition from weak/reversible binders to strong/irreversible adsorption onto aluminum oxide surfaces is observed. To elucidate effects of PEO-block length on the enzyme activable formation of antifouling coatings on aluminum oxide surfaces, a set of mefp-1-block-PEO bioconjugates with PEO-block lengths of 850, 3200 and 5200 g/mol is synthesized and investigated.


01.09.2014 - A direct biocombinatorial strategy towards next generation, mussel-glue inspired saltwater adhesives.
New Paper in Journal of the American Chemical Society has been published.
 
Biological materials exhibit remarkable, purpose-adapted properties that provide source of inspiration for designing new materials to meet the requirements of future applications. For instance, marine mussels are able to attach to a broad spectrum of hard surfaces under hostile conditions. Controlling wet-adhesion of synthetic macromolecules by analogue processes promises to strongly impact materials sciences by offering advanced coatings, adhesives and glues.



28.08.2014 - Hans Börner and Stefan Hecht (Humboldt-Universität zu Berlin, Berlin) organized the 2nd ERC-Grantees Conference on „Frontiers in Chemistry - The Basis for Advanced Materials“


It is our great pleasure to invite you the 2nd European meeting of ERC grantees in chemistry to be held in Berlin on August 28 & 29, 2014. The meeting Frontiers of Chemistry continues a tradition started in Strasbourg two years ago.
The aim of the conference is to gather some of the leading European experts in the field of chemical materials research, showcase their latest achievements, and discuss about future trends.

25.05.2014 - J.-F. Lutz (Institut Charles Sadron, UPR22 CNRS, Strasbourg) and H. G. Börner (Humboldt-Universität zu Berlin, Berlin) organized the EUPOC 2014 on precision polymers.



The objective of this conference will be to discuss a new side of macromolecular research: “Precision Polymers”. In particular, this conference will highlight new directions in polymer synthesis. Indeed, we believe that the polymer chemists of the 21st century have to explore options, which are beyond conventional macromolecular engineering. For instance, the control over polymer architectures is nowadays not a challenge anymore. Recent tools such as controlled radical polymerizations or “click” chemistry allow a fine control of polymer architectures.
