Welcome to the Ulijn Group website. We develop molecular materials and systems using simple biological building blocks with unique properties, such as adaptability, transient responsiveness and molecular recognition. These properties open up new applications in wide ranging areas ranging from biomedicine to nanotechnology. [Group Members and Full Biography]
Sequence Adaptive Peptide-Polysaccharide Nanostructures by Biocatalytic Self-Assembly
In Yousef' latest paper published in Biomacromolecules, we show biomaterials that can dynamically adapt their structure and function by biocatalytic co-assembly. This is demonstrated by dynamic exchange of charged peptide sequences, to achieve selective amplification in the presence of cationic (chitosan) or anionic (heparin) biomacromolecules. The dynamic adaptive potential was demonstrated by sequential morphology changes depending on the sequence of polysaccharide addition. These results may pave the way to materials able to undergo dynamic morphogenesis.
Ulijn Group at ASRC
The Strathclyde and New York sections of the Ulijn Group enjoyed an fun and action packed week in New York with our annual large group meeting followed by the Active & Adaptive Materials conference at ASRC.
