dc.description | Gold nanoparticles (AuNPs), multi-branched gold nanoparticles (MBGNs), and silica-coated MBGNs (MBGNs-silica) were studied for rhodamine B (RB) and a-glucose detection at low concentration. The MBGNs SPR band in the NIR, which is tunable, is useful for SERS that was demonstrated using rhodamine B and a-glucose as probe molecules with detection limits of 50 pM and 5 mM (90 mg dL1),
respectively, much lower than that using regular AuNPs. The SERS signals of RB and a-glucose using MBGNs-silica are further enhanced with respect to AuNPs and MBGNs, which is attributed to the aggregation of the MBGNs and a stronger interaction. In the case of a-glucose, the functionalization process performed to both, a-glucose molecules and MBGNs, improves the interaction and allows
measurements at low concentration. | |
