Structure and activity of apoferritin-stabilized gold nanoparticles

Reduction of 4‐Nitrophenol as a Model Reaction for Nanocatalysis

“…Research on biomolecule-inorganic NP assemblies [73,129] is becoming popular as a result of their environmentally friendly characteristics, which are in line with the principles of "green chemistry".…”

“…Th e Au NPs were only eff ective for the fi rst cycle; they deactivated in the 2nd cycle. Another example of a stabilizing biomolecule is Horse spleen apoferritin (HSAF) [129], which was used with Au NPs for complete reduction.…”

Immobilization of Apoferritin‐Templated Seeds for Si Nanowire Growth

“…For the synthesis of the Au nanoparticles inside apoferritin, a modified synthesis procedure compared to that described in the literature [10] was used to prevent formation of metal particles outside the protein shell and to avoid post-synthesis purification. 5 mg mL À1 apoferritin was incubated with HAuCl 4 in a buffer solution at pH 7.4.…”

“…[7] This feature enables the apoferritin molecules to be used as highly accurate templates for a preparation of metallic nanoparticles inside the cavity, which has already been seen for the preparation of various functional nanomaterials. [8][9][10] Besides the good solubility and the upper limit for the particle size provided by the protein shell, the protein can be easily modified and immobilized on surfaces in several ways. This unique advantage, offered by the protein, even enables patterning of large surface areas.…”

A Protein-Based Ferritin Bio-Nanobattery

“…Reconstitution using variations of this site-specific biomineralization process produces ferritins with an impressive variety of interesting and possibly technologically useful, but nonnatural, nanomineral cores [25][26][27][28]. Of interest in creating a bio-nanobattery are ferritins containing the oxidizing Co(OH) 3 and Mn(OH) 3 mineral cores with 500-2000 metal atoms per ferritin [21,29].…”
