Communicating particles

 

Icon communicating particlesOne major focus of our current research is on creating supraparticles which carry a unique ID, i.e., which possess a fingerprint.
Installing an ID in one single particle is achieved by assembling supraparticles from nano building blocks with well-defined physical properties in specifically defined ratios. We do this either with optical or magnetic systems. Furthermore, we equip particles with monitoring or recording functionalities. Our ultimate aim is to create „communicating particles“ which can be employed to track processes, keep materials in use, trace material components and enable smart recycling approaches.
