Dual functionality of ferrocene-based metallopolymers as radical scavengers and nanoparticle stabilizing agents

Abstract

The beneficial redox properties of ferrocene-based polymers have been utilized during in situ preparation of metallic nanoparticles, while such redox features also indicate great promise in applications as free radical...

Aptamer Clicked Poly(ferrocenylsilanes) at Au Nanoparticles as Platforms with Multiple Function[†]

“…a). This observation is in line with previous results for PFS‐stabilized nanoparticles [59,60] . Literature data indicate that aptamer grafting would further improve this stability via steric effects [54,55] .…”

“…This observation is in line with previous results for PFS-stabilized nanoparticles. [59,60] Literature data indicate that aptamer grafting would further improve this stability via steric effects. [54,55] To test this possibility, we compared the stability of aptamer-grafted AuNPs to that of AuNPs without aptamer (Figure 4.…”

“…[28,52] Here, we use redox-responsive polyelectrolytes based on poly(ferrocenylsilane) (PFS) backbones. [57,58] Coupled with the capacity of anionic PFS polyelectrolytes to provide additional electrosteric stabilization to colloidal nanoparticle dispersions, [59,60] aptamer-PFS-gold nanoparticle hybrids show promise as highly stable colloidal systems even at electrostatic screening conditions.…”
