In this regard, the growth of gold nanocrystals persists as long as the crystallization sites are not blocked by the capping agent and as long as the gold (III) salt is available in the reaction medium.…”

“…Interestingly, an increase of the concentration of amino acids leads to the formation of small particles (4 to 30 nm) which ripen to form larger particles such as triangles and hexagons. Similarly, bovine serum albumin provided small Au-NPs of 2 nm after 12 h of reaction which slowly evolved to form nanoplates after 48 h of reaction [77]. Previously, investigation on three different proteins, namely, bovine serum albumin, Rituximab and Cetuximab revealed that bovine serum albumin was the only protein of the three able to reduce the gold salt to form gold nanotriangles [78].…”

Growth and time dependent alignment of KCl crystals in Hemoglobin LB monolayer

“…In addition, it is found in Fig. 5A that the diffraction peak corresponding to the (222) plane shifted toward higher angle by w2 and it might be due to the protein induced perturbation of the biomineralized KCl crystal [56]. Fig.…”

“…Our prediction regarding these mismatches may be due to the factor coming from the proteininduced mineralization. Xue et al also observed such kind of protein induced lattice mismatches, in case of gold nanoplate in Langmuir monolayer of bovine serum albumin [56]. In this regard, it is to be noted that the little amount of artifact may appear during local measurement in Fourier transform HR-TEM data (fringe pattern) than the X-Ray data (JCPDS data) and this may contribute in the calculation of mismatches in d-values.…”

Protein coated gold nanoparticles as template for the directed synthesis of highly fluorescent gold nanoclusters

“…(iii) Besides, the addition of AuNPs nanoparticle causes PL enhancement, which serves as spacer between BSA chains. Increased chain separation enhances intrachain character of the photogenerated excitons, subsequently, as decaying path declines, the PL intensity increases [34].…”
