Life-Like Self-Organising Laser Can Mimics Living Materials, Reconfigures in Changing Conditions

In a study, published in Nature, the team from Imperial College London have used an external laser to heat up a Janus particle, which was coated with light-absorbing material on one side. The microparticle clusters gathered around the coating and the lasing thus created could be turned on and off by tweaking the intensity of the external laser.
