Abstract
A plasmonics-active gold nanostar results from the following process: adding citrate stabilized gold seeds to a solution of tetrachloroauric acid (HAuCl4) under acidic conditions; and mixing a silver salt compound and a weak reducing agent simultaneously into the solution of HAuCl4 under conditions such that the plasmonics-active gold nanostar is produced. The plasmonics-active gold nanostar has a size of at least about 30 nm and up to about 80 nm, comprises a plasmon peak in the near-infrared region, comprises an optical label and a bioreceptor, and is a nucleic acid.
