“…36,37 By simply adding an extra cysteine to a peptide, the high affinity between the sulydryl group and gold can ensure a maximal conjugation. 38,39 Researchers have used a synthetic cysteine-terminated foot-and-mouth disease virus peptide to modify AuNPs as a virus vaccine. 23 Peptide-AuNPs induced a three-fold increase in the antibody response compared to conventional protein vectors.…”

“…The high attraction between sulfydryl and Au will approve a maximum relation through the morally added use of amore cysteine to a peptide, [357]. In order to adjust Au NPs as a virus vaccine, scientists have used the synthetic foot and mouth virus of cysteine [358,359]. In order to adjust Au NPs as a virus vaccine, scientists have used the synthetic foot and mouth virus of cysteine [342].…”

Gold nanoparticles (Au NPs) play a significant role in science and technology because of their unique size, shape, properties and broad range of potential applications. This review focuses on the various approaches employed for the synthesis, modification and functionalization of nanostructured Au. The potential catalytic applications and their enhancement upon modification of Au nanostructures have also been discussed in detail. The present analysis also offers brief summaries of the major Au nanomaterials synthetic procedures, such as hydrothermal, solvothermal, sol-gel, direct oxidation, chemical vapor deposition, sonochemical deposition, electrochemical deposition, microwave and laser pyrolysis. Among the various strategies used for improving the catalytic performance of nanostructured Au, the modification and functionalization of nanostructured Au produced better results. Therefore, various synthesis, modification and functionalization methods employed for better catalytic outcomes of nanostructured Au have been summarized in this review.

“…Consequently, a signal amplification protocol for SPR sensors is important for practical applications. Chen and coworkers deposited CB [7]-coated AuNPs/peptide-modified AuNPs multilayer films on the surface of an Au chip of an aSPR sensor [63]. For this purpose, a heptamer peptide consisting of a glycine pentamer with phenylalanine and cysteine end groups (NH 2 -Phe-Gly-Gly-Gly-Gly-Gly-Cys) was used.…”
