Information-Providing Magnetic Supraparticles: Particle Designs to Record Environmental Stimuli with Readout by Magnetic Particle Spectroscopy

Abstract

The ability to gather information about materials and products, such as their origin, physicochemical properties or history of experienced environmental stimuli, is valuable for quality control, predictive maintenance, delivery tracking, recycling, and more. Integrating additives capable of recording and storing information into materials offers a flexible approach to create “materials intelligence”. Common strategies utilize luminescent markers or DNA sequences that enable object identification and environmental impact monitoring.
