Description
Summary:Gold nanotriangles (Au NTs) with tunable edge length were synthesized via a green chemical route in the presence of the designed consensus sequence tetratricopeptide repeat (CTPR) protein, halide anions (Br − ) and CTPR-stabilized Ag seeds. The well-defined morphologies, tailored plasmonic absorbance from visible-light to the near infrared (NIR) region, colloidal stability and biocompatibility are attributed to the synergistic action of CTPR, halide ions, and CTPR-stabilized Ag seeds. Biocompatible triangular gold nanoprisms with well-defined morphology, tailored plasmonic absorbance, and high colloidal stability are synthesized via seed-mediated biomineralizaton.
