The development of α,ε-hybrid peptide-stabilized magnetic nanoparticles and their application to fabricate a paper-based actuator has been reported. From single-crystal diffraction analysis, the nitropeptide has an extended structure with a geometry. The one-pot in situ multiple oxidation-reduction reaction of a synthetic nitropeptide solution in ammonium hydroxide and FeCl leads to the formation of FeO nanoparticles. The reduction reaction replaces the nitro group with an amine group, which finally acts as capping agent for the stabilization of the FeO nanoparticles. Paper-based soft magneto machines with multivariant actuation modes such as contraction-expansion, bending, and uplifting locomotion have been studied. The device has potential as controllable paper-based soft robots.
α,ε-杂合肽稳定的磁性纳米颗粒的开发及其在制造纸基致动器中的应用已有报道。通过单晶衍射分析，硝肽具有伸展结构和特定几何形状。在氢氧化铵和氯化铁中，合成硝肽溶液的一锅原位多氧化还原反应导致形成FeO纳米颗粒。还原反应将硝基替换为胺基，该胺基最终作为封端剂用于稳定FeO纳米颗粒。具有收缩-膨胀、弯曲和提升运动等多变量驱动模式的纸基软磁机器已得到研究。该装置有潜力成为可控的纸基软机器人。
