bearing the MRI-active nucleus
A61K 49/1803 . . . { Semi-solid preparations, e.g. ointments, gels, hydrogels }
A61K 49/1806 . . . { Suspensions, emulsions, colloids, dispersions }

A61K 49/1812 . . . . { liposomes, polymersomes, e.g. immunoliposomes }
NOTE
-
If the paramagnetic metal complexes are covalently linked to the
bilayered membrane, then the A61K 49/085 subgroup being also given.
Liposomes modified on their external surface by a targeting agent, e.g.
an antibody are classified in A61K 49/1812 without further indication for
the targeting agent

A61K 49/1818 . . . { particles, e.g. uncoated or non-functionalised microparticles or nanoparticles }
NOTE
-
For nanoparticles, i.e. having a size or diameter smaller than 1
micrometer, the subgroups B82Y 5/00 and B82Y 15/00 are also given
A61K 49/1821 . . . . { coated or functionalised microparticles or nanoparticles }

nano-emulsions A61K 49/1806 ; micelles A61K 49/1809 ) }
A61K 49/1827 . . . . . . { having a (super)(para)magnetic core, being a solid MRI-active
material, e.g. magnetite, or composed of a plurality of MRI-active,
organic agents e.g. Gd-chelates, or nuclei, e.g. Eu3+, encapsulated or
entrapped in the core of the coated or functionalised nanoparticle }
A61K 49/183 . . . . . . . { having a (super)(para)magnetic core coated or functionalised with
an inorganic material or being composed of an inorganic material
entrapping the MRI-active nucleus, e.g. silica core doped with a
MRI-active nucleus }
A61K 49/1833 . . . . . . . { having a ( super ) (para)magnetic core coated or functionalised

than 8 carbon atoms in the main chain }
A61K 49/1839 . . . . . . . . { the small organic molecule being a lipid, a fatty acid having 8
or more carbon atoms in the main chain, or a phospholipid }
A61K 49/1842 . . . . . . . . { the small organic molecule being a phosphate or a
phosphonate, not being a phospholipid }
A61K 49/1845 . . . . . . . . { the small organic molecule being a carbohydrate (
monosaccharides, discacharides ) }
A61K 49/1848 . . . . . . . . { the small organic molecule being a silane }
