This invention relates to methods and systems for removing plaque from arteries and blood vessels in human subjects non-invasively utilizing coated superparamagnetic nanoparticles introduced into the human bloodstream and controlled by external magnetic fields to effect plaque removal. Magnetic nanoparticles are injected into a patient, and magnetic fields are used to move the nanoparticles to the site of an arterial blockage. The nanoparticles are then oscillated by means of an alternating current source and oscillating magnetic field. The nanoparticles impact the plaque deposit, causing it to break up, so that it may be safely disintegrated, dissolved in the bloodstream, digested by enzymes or ions and/or removed with the nanoparticles themselves. The nanoparticles are removed by a unipolar magnetic field directing them to be removed at the point of injection or alternative location in the body. The nanoparticles are also removed by natural bodily functions. The methods and systems are directed to the emergency clearance of arteries in the human body, and the routine annual and quarterly clearance and preventative maintenance of arteries in the human body.

Provided is an ε-iron oxide type ferromagnetic powder with a powder pH within a range of 4.8 to 6.8; and a method for manufacturing the ε-iron oxide type ferromagnetic powder and a composition containing at least the ε-iron oxide type ferromagnetic powder and a solvent.

The present invention relates to magnetic single-core nanoparticles, in particular stable dispersible magnetic single-core nanoparticles (e.g. single-core magnetite nanoparticles) having a diameter between 20 and 200 nm in varied morphology, and the continuous aqueous synthesis thereof, in particular using micromixers. The method is simple, quick and cost-effective to perform and is carried out without organic solvents. The single-core nanoparticles produced by the method form stable dispersions in aqueous media, i.e. not having a tendency to assemble or aggregate. In addition, the method offers the possibility of producing anisotropic, super-paramagnetic, plate-shaped nanoparticles which, due to their shape anisotrophy, are extremely suitable for use in polymer matrices for magnet field-controlled release of active substances.

Biomimetic magnetic nanoparticles comprising MamC. The present invention provides superparamagnetic biomimetic nanoparticles comprising magnetite, which can be produced using a scalable process. In addition, these nanoparticles exhibit promising properties, since, if functionalized, they can be converted into drug carriers or contrast agents for obtaining clinical images. They can also be used in clinical setting to purge bone marrow, as molecule separators, and/or for environmental applications as biosensors. These nanoparticles, coupled to a drug, can be encapsulated in liposomes, thereby obtaining magnetoliposomes, which can be functionalized for use in the targeted delivery/release of drugs. In addition, mixtures of magnetoliposomes (functionalized or not with a targeting agent) and functionalized biomimetic magnetic nanoparticles or liposomes containing mixtures of functionalized BMNPs and MNPs can be used to combine different treatments, such as, for example, targeted delivery/release of drugs and hyperthermia.
