….. here’s the “feel good” lie, quoted below –
(“wouldn’t it be wonderful to clean up water like this?” oh happy happy joy joy!. here’s the reality: These particles are HIGHLY TOXIC, and liberate themselves under various frequencies, and this is well known, and well documented. and you’d never know it, because they’re too small to see. They are a weapon.

Lead contamination in water has devastating impacts on human health and the environment. To combat this issue, researchers have developed a new sponge capable of filtering lead and other harmful contaminants.Scientists at Northwestern University have developed a highly efficient sponge that filters out a range of con including heavy metals like arsenic, cobalt, and chromium.
In a test conducted on tap water with lead levels exceeding 1 part per million, the sponge successfully achieved lead filtration to undetectable levels after just one use. Impressively, the researchers recovered the filtered metals, allowing for the sponge’s reuse in multiple cycles. This breakthrough positions the sponge as a promising solution for various applications, from household water filters to large-scale environmental remediation projects.
The exceptional performance of the sponge can be attributed to its ultrathin nanoparticle composed of magnetic iron oxide. Magnetic iron oxide is cost-effective, readily accessible, non-toxic, and possesses a high surface area with reactive sites for efficient adsorption.
When immersed in contaminated water, the nanoparticle-coated sponge effectively captures lead ions, reducing the lead concentration to safe levels for drinking water.
The sponge can be easily rinsed with mildly acidified water, releasing the captured lead ions and enabling reuse. While there is a slight decline in performance after the initial use, the sponge still recovers over 90% of the ions during subsequent cycles, ensuring its long-term effectiveness.
The sponge’s ability to efficiently gather and recover heavy metals proves invaluable, particularly in removing rare and critical metals like cobalt from water sources. This process enables their recycling for use in essential products such as batteries.
The researchers have also established design principles that can guide the development of similar platforms, facilitating targeted metal capture and providing a standardized scale for evaluating different coatings and adsorbents.
With its potential applications in commercial water filters, environmental cleanup initiatives, and water reclamation and treatment facilities, the sponge holds immense promise in addressing water quality concerns at both local and global levels. Its versatility and effectiveness make it a valuable tool for protecting water resources and promoting sustainable practices.

THIS IS NOT A SOLUTION.
The following abstract is from a DOI on PubMed (which is a great place to see how something can mess you up, if you understand chemistry and human biology).
Abstract Iron oxide nanoparticles are the basic components of the most promising magnetoresponsive nanoparticle systems for medical (diagnosis and therapy) and bio-related applications. Multi-core iron oxide nanoparticles with a high magnetic moment and well-defined size, shape, and functional coating are designed to fulfill the specific requirements of various biomedical applications, such as contrast agents, heating mediators, drug targeting, or magnetic bioseparation. This review article summarizes recent results in manufacturing multi-core magnetic nanoparticle (MNP) systems emphasizing the synthesis procedures, starting from ferrofluids (with single-core MNPs) as primary materials in various assembly methods to obtain multi-core magnetic particles. The synthesis and functionalization will be followed by the results of advanced physicochemical, structural, and magnetic characterization of multi-core particles, as well as single- and multi-core particle size distribution, morphology, internal structure, agglomerate formation processes, and constant and variable field magnetic properties. The review provides a comprehensive insight into the controlled synthesis and advanced structural and magnetic characterization of multi-core magnetic composites envisaged for nanomedicine and biotechnology.
the reality: they’re already doing all of that. and yes it’s highly toxic to the human body. and yes.. it’s graphene oxide, and other types of iron oxide.
