Multilayered polyelectrolyte functionalized gold nanorods (GNRs) are reported for the conjugation of and sensitive detection of bio-molecules. Multilayered polyelectrolyte functionalized GNRs can significantly improve the biocompatibility of cetyltrimethylammonium bromide ( CTAB) coated GNRs in a bio-environment and can diminish the toxicity induced by CTAB. Biotin, bovine serum albumin (BSA)-biotin and streptavidin are conjugated to polyelectrolyte functionalized GNRs, and the conjugates can serve as a platform for many biotin-streptavidin-based biological applications. Through the robust self-assembly effect of GNRs, biotin-conjugated GNRs are also utilized as a very sensitive probe for the detection of a small amount of streptavidin.
