Biotic Superparamagnetic Nanoparticles From Colchicum Ritchii
Summary
Veeramani Chinnadurai, Khalid A. Al-Numair, and Mohammed A. Alsaif filed US Patent Application US20260108579A1 with the USPTO on January 17, 2025, published April 23, 2026, covering a method for preparing biotic superparamagnetic nanoparticles. The method involves combining a Colchicum ritchii plant extract with a ferric chloride solution and adding sodium hydroxide to produce the nanoparticles. CPC classifications indicate pharmaceutical applications including drug delivery systems and therapeutic indications for obesity and diabetes.
“A method of preparing biotic super-paramagnetic nanoparticles can include combining a Colchicum ritchii plant extract with a ferric chloride solution to provide a mixture and adding sodium hydroxide solution to the mixture to provide the super-paramagnetic nanoparticles.”
About this source
USPTO classification A61K covers pharmaceutical preparations: formulations, dosage forms, combination therapies, delivery systems, and the vehicles that carry active ingredients. Every newly published application in A61K lands in this feed, around 245 a month. Applications publish 18 months after filing, so this feed reveals what pharma formulators at major sponsors and generics were working on in the prior year and a half. Watch this if you compete in drug formulation, file freedom-to-operate analyses, scout competitive drug products before clinical readouts, or follow novel delivery platforms like nanoparticles, lipid carriers, and long-acting injectables.
What changed
US Patent Application US20260108579A1 was published by the USPTO on April 23, 2026. The application, filed January 17, 2025 (Application No. 19028150), discloses a method for preparing biotic superparamagnetic nanoparticles by combining Colchicum ritchii plant extract with ferric chloride solution and adding sodium hydroxide. The CPC classifications (A61K 36/88, A61K 9/5115, A61K 9/5192, A61K 47/02, A61P 3/04, A61P 3/10) indicate pharmaceutical applications including drug delivery systems and therapeutic uses for obesity and diabetes management.
Inventors and applicants should monitor the prosecution of this application for any office actions requiring response. Competitors developing similar biotic superparamagnetic nanoparticle methods may wish to conduct freedom-to-operate analyses once the application matures toward grant.
