Silver ferrite and cobalt ferrite dispersed castor oil polyurethane nanocomposites: Quenching studies of bovine serum albumin

Synthesis, physicochemical, and antimicrobial characteristics of novel poly(urethane-siloxane) network/silver ferrite nanocomposites

“…PU nanocomposite materials, built by dispersing \ 5 wt% of inorganic nanoparticles in an organic polymer matrix, offer very desirable advantages over other, non-nano-PU materials, as the nanocomposites have enhanced thermal, surface, mechanical, and biological properties [2,[29][30][31][32]. The desirability of PU nanocomposites is mostly due to the ease by which their functional properties can be fine-tuned, simply by choosing different nanofillers, for example, clay [33], graphene [34], carbon nanotubes [35], nanosilver [36], TiO 2 [37], or magnetic nanoparticles such as Fe 3 O 4 [38], and binary-ferrites [39], by adjusting their content and by the nanofiller preparation procedure. Among them, ferrite nanoparticles are deemed as having extremely attractive potential for use in the medical coatings field.…”

“…Agarwal et al [45] prepared nanocomposites of Ni 0.5 Zn 0.5 Fe 2 O 4 /PU and indicated that increasing nanofiller concentration ([ 1 wt%) weakens the final PU, because of irregular distribution and agglomeration. Riaz et al [39] prepared castor oil-based PU nanocomposites with cobalt ferrite and silver ferrite and investigated their biological potential through their interaction with bovine serum albumin (BSA). They found that they could achieve the solicited binding with BSA by controlling the level of nanoferrite in the PU matrix.…”
