The present invention relates to methods of fabrication of hollow shells/spheres/particles, core-shell particles and composite materials made from these particles.

In a method for manufacturing core-shell particles including core particles and a shell, the constituent metal elements of the core particles and the shell are different from each other. 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.

A method of encapsulating content with calcium alginate membrane to form a capsule. The method includes embedding sodium alginate into a traditional gelatin ribbon used in gelatin encapsulation, adding calcium to a fill material, encapsulating the fill material, and then denaturing the gelatin in the shell. An exemplary use of this method is to form throwable paintballs; however, other products could be formed using this process. A paintball formed by this process is also disclosed.

With an aim to provide an oxide particle with controlled color characteristics, the present invention provides a method for producing an oxide particle, wherein the color characteristics of the oxide particle are controlled by controlling a M-OH bond/M-O bond ratio, which is a ratio of a M-OH bond between an element (M) and a hydroxide group (OH) to a ratio of an M-O bond between the element (M) and oxygen (O), where the element (M) is one or plural different elements other than oxygen or hydrogen included in the oxide particle selected from metal oxide particles and semi-metal oxide particles. According to the present invention, by controlling the M-OH bond/M-O bond ratio of the metal oxide particle or the semi-metal oxide particle, the oxide particle with controlled color characteristics of any of reflectance, transmittance, molar absorption coefficient, hue, and saturation can be provided.

A method for preparing fluorescent-encoded microspheres coated with metal nanoshells is disclosed herein. By using SPG method, metal nano-material modified with a certain ligand is used as a new surfactant in the emulsification process, and different kinds and different amounts of fluorescent materials are doped into polymer microspheres to prepare fluorescent-encoded microspheres with different fluorescent-encoded signals and uniformly coated metal nanoshells in one step. The prepared fluorescent-encoded microsphere comprises a metal nanoshell, a polymer, and a fluorescent-encoded material. The fluorescent-encoded microsphere has a particle size of 1 μm˜20 μm, CV of less than 10%, which can be used for protein/nucleic acid detection. The preparation method has the advantages of simple process, high surface coating rate, good uniformity and controllable LSPR peaks, which can solve the problems of existing commonly used metal nanoshell coating methods such as low surface coating rate, poor uniformity, complex preparation process and uncontrollable local surface plasmon resonance (LSPR) peaks, etc.
