New directions in Janus particle-based bioanalytical methods

Submission status

Janus particles, named after the two-faced Roman god Janus, are microparticles with different surface structures, that combine one or more chemical properties in a single unit. Unlike conventional particles used in analytical science, two-faced Janus particles provide asymmetry and directionality and can combine different or even incompatible properties within a single particle. The broken asymmetry of such particles and the anisotropy impart them with attractive analytical properties allowing them to solve complex challenges. Indeed, using the surface anisotropy of Janus particles allows to spatially decouple different sensing functions that would otherwise interfere with each other. The asymmetric structure has been exploited to develop self-propelled Janus micromotors towards actively moving biosensors. This topical collection aims to cover recent advances in the use of Janus microparticles and micromotors as novel analytical tools in biosensing and bioimaging.
