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.
在设计的共有序列四肽重复（CTPR）蛋白、卤化物阴离子（Br(-)）和CTPR稳定的Ag种子存在的情况下，通过绿色化学路线合成了具有可调边缘长度的金纳米三角形（Au NTs）。明确的形态、从可见光到近红外（NIR）区域的定制等离子体吸收、胶体稳定性和生物相容性归因于CTPR、卤化物离子和CTPR稳定的Ag种子的协同作用。
