Gold nanoparticles decorated with monosaccharides and sulfated ligands as potential modulators of the lysosomal enzyme N-acetylgalactosamine-6-sulfatase (GALNS)
ending in thiol groups, which enable attachment of the glycoconjugates to the goldsurface, have been prepared. manno‐GNPs with different spacers and variable density of mannose (oligo)saccharides have been obtained and characterized. Surface plasmon resonance (SPR) experiments with selected manno‐GNPs have been performed to study their inhibition potency towards DC‐SIGN binding to gp120. The tested manno‐GNPs

The present invention provides methods and compositions for carbohydrate encapsulated nanoparticle based mass spectrometry. For example, the present invention provides methods of screening samples for carbohydrate binding molecules, methods of characterizing carbohydrate binding epitopes in target molecules, and MALDI matrix compositions comprising carbohydrate encapsulated nanoparticles.
The present invention provides carbohydrate encapsulated nanoparticles. In particular, the present invention provides metallic nanoparticles (e.g. gold nanoparticles) that are encapsulated in biologically important carbohydrate molecules, such as sugars, sugar derivatives, P-blood group antigens and analogues thereof. The present invention also provides methods of employing these carbohydrate encapsulated nanoparticles in diagnostic and therapeutic applications.

Gold nanoparticles decorated with monosaccharides and sulfated ligands as potential modulators of the lysosomal enzyme <i>N</i>-acetylgalactosamine-6-sulfatase (GALNS)
Modulation of N-acetylgalactosamine-6-sulfatase (GALNS) activity is a promising tool for treating metabolic disorders, neuropathic pain, and cancer. Gold nanoparticles coated with sugar and sulfated ligands were prepared and assayed for this purpose.
