pH- and redox-responsive polysaccharide-based microcapsules with autofluorescence for biomedical applications.

Liang Gao et al.

Chemistry (Weinheim an der Bergstrasse, Germany), 18(11), 3185-3192 (2012-02-22)

Autofluorescent microcapsules were assembled by covalent cross-linking of polysaccharide alginate dialdehyde (ADA) derivative and cystamine dihydrochloride (CM) through a layer-by-layer (LBL) technique. The formulated Schiff base and disulfide bonds render capsules with pH- and redox-responsive properties for pinpointed intracellular delivery

Colloidal stability of gold nanoparticles modified with thiol compounds: bioconjugation and application in cancer cell imaging.

Jie Gao et al.

Langmuir : the ACS journal of surfaces and colloids, 28(9), 4464-4471 (2012-01-27)

Gold nanoparticles (GNPs) are attractive alternative optical probes and good biocompatible materials due to their special physical and chemical properties. However, GNPs have a tendency to aggregate particularly in the presence of high salts and certain biological molecules such as

Mapping of O-GlcNAc sites of 20 S proteasome subunits and Hsp90 by a novel biotin-cystamine tag.

Thorsten Overath et al.

Molecular & cellular proteomics : MCP, 11(8), 467-477 (2012-05-05)

The post-translational modification of proteins with O-GlcNAc is involved in various cellular processes including signal transduction, transcription, translation, and nuclear transport. This transient protein modification enables cells or tissues to adapt to nutrient conditions or stress. O-Glycosylation of the 26
