  • Title: Glyconanoparticles: multifunctional nanomaterials for biomedical applications.
    Author: García I, Marradi M, Penadés S.
    Journal: Nanomedicine (Lond); 2010 Jul; 5(5):777-92. PubMed ID: 20662648.
    Abstract:
    Metal-based glyconanoparticles (GNPs) are biofunctional nanomaterials that combine the unique physical, chemical and optical properties of the metallic nucleus with the characteristics of the carbohydrate coating. The latter characteristics comprise a series of advantages that range from ensuring water solubility, biocompatibility and stability to targeting properties. The selection of suitable carbohydrates for specifically targeting biomarkers opens up the possibility to employ metallic GNPs in diagnostics and/or therapy. Within the vast nanoscience field, this review intends to focus on the advances of multifunctional and multimodal GNPs, which make use of the 'glycocode' to specifically address pathogens or pathological-related biomedical problems. Examples of their potential application in antiadhesion therapy and diagnosis are highlighted. From the ex vivo diagnostic perspective, it can be predicted that GNPs will soon be used clinically. However, the in vivo application of metallic GNPs in humans will probably need more time. In particular, major concerns regarding nanotoxicity need to be exhaustively addressed. However, it is expected that the sugar shell of GNPs will lower the intrinsic toxicity of metal nanoclusters better than other non-natural coatings.
