Covalently Reinforced Alginate Gels

Scaffolds for Tissue Engineering / Hydrogels

Heterobifunctional linear polyethylene glycol (PEG) was utilized to functionalize alginate’s polymeric backbone with multiple alkyl azide end groups. In the presence of PEG and alginate-based crosslinkers, ionically-cro...

Dendritic Conformal Coating of Pancreatic Islets

Conformal Coating / Layer-by-Layer

Highly branched and spatially restrictive polymeric materials were utilized to deposit conformal coatings on pancreatic islets or other surfaces via the layer-by-layer film deposition technique. The Staudinger ligation was ut...

Enzyme-Quantum Dot Conjugate

Molecular Recognition / Diisopropyl Fluorophosphate

Organophosphorus acid anhydrolase was used as matrix for direct synthesis and functionalization of CdS quantum dots in aqueous solutions. This enzyme-quantum dot system was effective at fluorometrically detecting micromolar l...

Layer-by-Layer Deposition of Enzyme

Molecular Recognition / Paraoxon

A multilayer film of chitosan, 3.5 nm negatively charged CdSe quantum dots, and organophosphorus hydrolase was deposited onto quartz slide via the layer-by-layer deposition technique of polyelectrolytes. Concentration of para...

Peptide-Coated Quantum Dots

Molecular Recognition / Copper(II)

It was observed that the photoluminescence intensity of cadmium chalcogenides quantum dots (QDs) was altered by some biological relevant metallic ions in aqueous solutions. In particular, copper(II) usually had a significant ...
