A method for producing porous particles of a cross-linked polymer, and porous particles that can be produced according to the method are disclosed. The porous particles of a crosslinked hydroxy- or amino-group-containing polymer have a relatively low swelling factor. A composite material contains the porous particles dispersed in a continuous aqueous phase. The porous particles, or the composite material, are used for purifying organic molecules and for bonding metals from solutions. A filter cartridge contains the porous particles of a cross-linked polymer or the composite material.

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.

The manufacturing method provided by the present invention is a method for manufacturing core-shell particles that includes core particles and a shell, the constituent metal elements of the foregoing being different from each other. In the present invention, a quinone-containing core particle dispersion containing at least core particles consisting of a first metal, hydroquinone (HQ), benzoquinone (BQ), and a second metal compound including a second metal element for making up the shell is prepared, and a reduction treatment is performed on the quinone-containing core particle dispersion, through addition of a reducing agent, to form a shell including the second metal element as a main constituent element, on the surface of the core particles. A mass ratio: HQ/BQ ratio of added hydroquinone (HQ) and benzoquinone (BQ) is 0.1 to 120.
