“…Based on this strategy, Au NPs functionalized with monosaccharides (glucose), disaccharides (maltose), and tetrasaccharides (Le y ) were prepared and applied to the studies of various biological interactions 43, 44. Later, several other research groups utilized a similar strategy to produce Au and Ag glyconanoparticles using thiolated carbohydrates 45–51. Furthermore, thiolated carbohydrate derivatives have been adopted in the preparation of glyco‐quantum dots (GQDs) 52–54.…”

Glyconanomaterials, nanomaterials carrying surface-tethered carbohydrate ligands, have emerged and demonstrated increasing potential in biomedical imaging, therapeutics, and diagnostics. These materials combine the unique properties of nanometer-scale objects with the ability to present multiple copies of carbohydrate ligands, greatly enhancing the weak affinity of individual ligands to their binding partners. Critical to the performance of glyconanomaterials is the proper display of carbohydrate ligands, taking into consideration of the coupling chemistry, the type and length of the spacer linkage, and the ligand density. This article provides an overview of the coupling chemistry for attaching carbohydrate ligands to nanomaterials, and discusses the need for thorough characterization of glyconanomaterials, especially quantitative analyses of the ligand density and binding affinities. Using glyconanoparticles synthesized by a versatile photocoupling chemistry, methods for determining the ligand density by colorimetry and the binding affinity with lectins by a fluorescence competition assay are determined. The results show that the multivalent presentation of carbohydrate ligands significantly enhances the binding affinity by several orders of magnitude in comparison to the free ligands in solution. The effect is sizeable even at low surface ligand density. The type and length of the spacer linkage also affect the binding affinity, with the longer linkage promoting the association of bound ligands with the corresponding lectins.

“…Therefore, their synthesis and stabilization are very difficult tasks. A number of methods have been reported for the synthesis of metal nanoparticles in aqueous solution using stabilizing agents such as citrate, [14][15][16] starch, [17][18][19] gum arabic, [20][21][22] and polymers. [23,24] The size-dependent properties of nanomaterials make them interesting and technologically important.…”

“…(1), in which the Eu complex should contain the functional group which has strongh interaction with noble metal. So the ligand structure is very important to obtain the SEF function as reported in previous works [32,39,40]. The interaction of different molecules (Rhodamine B and Rhodamine 6G) with noble metallic spheroids leads to a different photophysics and photochemistry than that found in homogeneous phases.…”

Recent theoretical progress in understanding the effect of noble metal nanoparticles on the luminescent properties of europium complex was reviewed. The observed enhancement fluorescence results from surface-enhanced fluorescence (SEF) based on the surface plasmon resonance (SPR) of noble metal nanoparticles. And the observed quenching fluorescence is attributed to the re-absorption of surface plasmon resonance and noble metal nanoparticles scattering. And then the enhancing and quenching effects strongly depend on size, shape, concentration, surrounding medium of noble metal nanoparticle and the structure of europium complex. Furthermore, the mechanism of surface-enhanced fluorescence, and physical process between noble metal nanoparticles and europium complex were also discussed in detail. These discussions are very important to further improve enhancement factor, which is key to application in optical materials for the surface-enhanced fluorescence phenomenon of noble metal nanoparticles.
