The present invention provides liposomes loaded with chelating agents, pharmaceutical formulations including these liposomes and methods of making chelating agent liposomes. Because the chelating agents are loaded in the liposome with high efficiencies, the liposomes are of use in treatment of metal ion overload in subjects. The liposomes can also contain essential trace metals to compensate for the off target effect of removal of endogenous non-target trace metals by administration of the chelator. The liposomes can include two or more different chelating agents of different structures and affinities for metal ions.

A method of stabilizing electromagnetically charged particles, which includes coating electromagnetically charged particles with a protective layer; and etching the protective layer to produce a porous protective layer on the electromagnetically charged.

A nanocomposite for detection and treatment of a target of interest including tumor cells or pathogens includes at least one nanostructure, each nanostructure having a core and a shell surrounding the core; a reporter assembled on the shell of each nanostructure; and a layer of a treating agent and a targeting agent conjugated to the reporter. In use, the nanocomposite targets to the target of interest according to the targeting agent and releases the treating agent and the nanostructure therein for therapeutic treatment of the target of interest, and the target of interest transmits at least one signature responsive to the reporter for detection of the target of interest.

A capsule composition containing a capsule and a stabilizing agent. The capsule has an oil core containing an active material and a capsule wall encapsulating the oil core. The active material is a fragrance, a flavor, a malodor counteractant, or a combination thereof. The wall is formed of polyurea or polyurethane. The capsule composition has 20 ppm or greater of the stabilizing agent, which is a multi-functional amine, an amino acid, a polymer mixture, or a combination thereof. Also disclosed is a consumer product containing this capsule composition.

A flowable, stable silica capsule formulation composed of a silica capsule suspension and an adjuvant for use in a personal care product, a beauty care product, a fabric care product, a home care product, a personal hygiene product, an oral care product is provided.

What are proposed are microcapsules comprising (a) a core comprising at least one active, and (b) a capsule wall,
wherein the capsule wall consists of at least three polymer layers and at least one of the polymer layers consists of a first phenolic resin, wherein the first phenolic resin comprises 3% to 50% by weight of moieties that derive from at least one aromatic polyol, and at least one further polymer layer consists of a second phenolic resin, wherein the second phenolic resin comprises 3% to 50% by weight of moieties that derive from at least one triphenol.

Polyurea capsules that encapsulate active materials in polymeric walls resulting from the polymerization of an aliphatic polyisocyanate and a cross-linking agent such as a diamine, amphoteric amine or guanidine amine/salt are provided as are consumer products containing said polyurea capsules and for methods for producing such capsules.
