Six-faced particles | Nature

Access through your institution Buy or subscribe Janus particles, named after the two-faced Roman god, are solid particles of two halves, each with different physical properties and with

applications that include drug delivery. But Shoji Takeuchi and his colleagues at the University of Tokyo have gone beyond Janus's two faces and made gel spheres with up to six distinct

sections. The particles are about 100 micrometres in diameter and, when each section is permeated with different fluorescent nanobeads, look like beach balls. The researchers also used

their method to produce Janus particles holding magnetic particles and living cells in their separate halves (PICTURED). This is a preview of subscription content, access via your
