Magnetically "Programming" Cobalt-Doped Iron Oxide Nanoparticles for Localized Induction Heating: Triggering a Collective Effect of Magnetic Moment Alignment on Demand.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Induction heating, a contactless and efficient method for generating heat via alternating magnetic fields (AMFs), has evolved from simple thermal applications to precise process control in fields like catalysis, self-healing, and debonding. Magnetic nanoparticles (NPs) play a key role as heat mediators, with heating properties adjustable via composition, size, and interactions. However, spatially precise heat control remains challenging. Current strategies rely on external AMF adjustments or material modifications, but lack an inherent mechanism to predefine which particles or regions will be activated for induction heating, limiting applicability in structured materials or complex environments. Here, it is shown that pre-magnetizing cobalt-doped iron oxide NPs with a static magnetic field irreversibly enhances their heating rates by up to a factor of 40. This process permanently alters their magnetic properties, enabling selective heating independent of AMF modulation. The extent of activation scales with cobalt content, introducing a material-intrinsic thermal switch. Furthermore, assembling these NPs into supraparticles facilitates integration into functional materials. By enabling spatially resolved and selective heat generation, this strategy advances the control of induction heating at the material level. It opens new possibilities for on-demand, pre-programmable, spatially resolved thermal activation in composite materials, smart adhesives, and targeted energy delivery in complex systems.
