Small, Volume 21, Issue 13, April 2, 2025.Magnetic supraparticles (SPs) serve as ID‐tag or recorder for environmental stimuli in objects of interest. On top of the interactions within (intra‐SP interactions), also the interactions between SPs (inter‐SP interactions) are crucial for such applications and can alter the magnetic readout.
