One-Pot Synthesis of Multiple Stimuli-Responsive Magnetic Nanomaterials Based on the Biomineralization of Elastin-like Polypeptides.

ABSTRACT: Synthesis of multiple stimuli-responsive magnetic nanomaterials in a green way remains as a big challenge currently. Herein, temperature-responsive elastin-like polypeptides (ELPs) were designed to involve in the biomimetic mineralization and successfully prepared magnetic nanoparticles (MNPs) (named ELPs-MNPs) with multiple responsiveness (temperature, magnetic, and biomimetic silicification responsiveness) in one pot. ELPs-MNPs were identified as cubic nanomaterials with an average size of about 32 nm and in line with the classic ferromagnetic behavior. Interestingly, ELPs-MNPs show clearly lower critical solution temperature phase behavior with a transition temperature of 36 °C. Moreover, ELPs-MNPs can spontaneously trigger the biosilicification of tetramethyl orthosilicate (TMOS) to en
