A platform for functionalization of cellulose, chitin/chitosan, alginate with polydopamine: A review on fundamentals and technical applications Hasselt University
Nature provides concepts and materials with interesting functionalities to be implemented in innovative and sustainable materials. In this review, it is illustrated how the combination of biological macromolecules, i.e. polydopamine and polysaccharides (cellulose, chitin/chitosan, alginate), enables to create functional materials with controlled properties. The mussel-adhesive properties rely on the secretion of proteins having ...
Remote functionalization University of Antwerp
A protocol for the Pd-catalyzed C5(sp3)-H arylation of readily available 1-Boc-3-(picolinoylamino)piperidine with iodo(hetero)arenes is reported. The substrate can be obtained from a biorenewable feedstock, namely l-arginine. The use of the right N1 protective group is decisive to get arylation. The addition of a catalytic amount of 2,6-dimethylbenzoic acid and performing the reaction at high concentration are important to achieve a high ...
Luminescence of Nanodiamond Driven by Atomic Functionalization: Towards Novel Detection Principles Hasselt University
High biocompatibility, variable size ranging from 5 nm, stable luminescence from its color centers, and simple carbon chemistry for biomolecule grafting make nanodiamond (ND) particles an attractive alternative to molecular dyes for drug-delivery. A novel method is presented that can be used for remote monitoring of chemical processes in biological environments based on color changes from photoluminescent (PL) nitrogen-vacancy (NV) centers in ...
In situ monitoring and optimization of CuAAC-mediated protein functionalization of biosurfaces Hasselt University
With the current trend to miniaturize bioactive surfaces to micro-or nanometer scale, the strategy of immobilization becomes more important. Therefore, there is a growing need for protein immobilization techniques that create both stable and homogeneously covered surfaces in a reproducible way. One of the most promising methods to achieve this is the combination of biological receptors with 'click' chemistry, like the Copper catalyzed Alkyne ...
Surface functionalization of 4D printed substrates using polymeric and metallic wrinkles Ghent University
Surface functionalization with polyethylene glycol and polyethyleneimine improves the performance of graphene-based materials for safe and efficient intracellular delivery by laser-induced photoporation Ghent University
Nanoparticle mediated laser-induced photoporation is a physical cell membrane disruption approach to directly deliver extrinsic molecules into living cells, which is particularly promising in applications for both adherent and suspension cells. In this work, we explored surface modifications of graphene quantum dots (GQD) and reduced graphene oxide (rGO) with polyethylene glycol (PEG) and polyethyleneimine (PEI) to enhance colloidal stability ...
End-group functionalization of poly(2-oxazoline)s using methyl bromoacetate as initiator followed by direct amidation Ghent University
Poly(2-alkyl/aryl-2-oxazoline)s (PAOx) are an alluring class of polymers for many applications due to the broad chemical diversity that is accessible for these polymers by simply changing the initiator, terminating agent and the monomer(s) used in their synthesis. Additional functionalities (that are not compatible with the cationic ring-opening polymerization) can be introduced to the polymers via orthogonal post-polymerization modifications. ...
Studies on functionalization of N,O-chelated isoquinoline-enol boron complexes Ghent University KU Leuven
Cellulose Nanofibers: Fabrication and Surface Functionalization Techniques Hasselt University
Cellulose fibers which consist of a bundle of stretched cellulose chain molecules with cellulose fibril are the smallest structural unit of plant fiber. These elementary fibrils or nanofibers are about 2–20 nm in diameter and a few micrometers in length. Cellulose nanofiber (CNF) is the world’s most advanced bio-nanomaterial. As the cellulose is the most abundant, renewable, and sustainable biopolymer on earth, it creates low environmental impact in ...
