Sensitivity of PS/CoPd Janus particles to an external magnetic field

Abstract

PS/CoPd Janus particles respond very sensitively to application of low external magnetic fields. Owing to the magnetic properties, the PS/CoPd particles may be used, for example, to sense the presence of weak magnetic fields as micro-magnetometers.

Magnetite‐based Janus nanoparticles, their synthesis and biomedical applications

“…Like this mythical god, Janus particles are also referred to as anisotropic particles with two different (physical, chemical) faces (Agrawal & Agrawal, 2019). This unique asymmetric property of Janus particles brings about a paradigm shift in particles considering their ability to be independently tailored, and over time Janus‐glass beads with only opposite polarity evolved into a vast variety of Janus nanoparticles (JNPs) with two sides of combined morphologies (S. Li, Liu, et al, 2022; Steinhaus et al, 2019; Tao et al, 2017), composition (Eichler‐Volf et al, 2021; Garbuzenko et al, 2014), and different functionalities (Khoee & Karimi, 2018; Khoee & Soleymani, 2019; Q. Yang et al, 2018; M. Zhang, Jiang, et al, 2021). Therefore, providing excellent opportunities which are not approachable in symmetric nanoparticles, including simultaneously using the distinct properties of both sides.…”
