Abstract
The rapid development of metal nanoparticles capped by an organic monolayer offers the possibility to create a whole new variety of products with novel characteristic, functions and applications. Among these, nanoparticles covered with carbohydrates (glyconanoparticles) constitute a good bio-mimetic model of carbohydrate presentation at the cell surface and are currently centered on many glycobiological and biomedical applications. In this study, a series of novel D-xylose gold nanoparticles (AuNPs) with linkages of alkyl or polyethylene glycol have been synthesized via D-xylosethiols, forming self-assembled monolayers on gold nanoparticles. The nano-gold solution, two carbohydrate derivatives and modified nano-gold solution were tested for cytotoxicity to check the biocompatibility. The MTT assay on NIH 3T3 cell lines confirmed that all the test materials showed no toxicity with the more than 90 % of cell viability in both low concentration (1 μM) and high concentration (100 μM), compared with the control.
