Abstract: Nanoparticles incorporating absorbing materials, e.g., an absorber dye, which under appropriate conditions exhibit chemiluminescence. The nanoparticles can be mesoporous silica nanoparticles or core-shell silica nanoparticles. The nanoparticles can be used as sensors to detect an analyte.

Abstract: A method for depositing particles onto a substrate. In one embodiment, the method providing a plurality of particles in a solvent or a matrix of solvents to form a solution; freezing the solution to form a target having a surface; irradiating the target with a light of a wavelength in the infrared region which is resonant with a vibrational mode of the target so as to vaporize the particles in the target without decomposing the particles; and depositing the vaporized particles onto the substrate at a deposition rate to form a film of particles thereon, where the substrate is positioned such that the substrate and the target define a distance therebetween.

Abstract: Amphiphilic block copolymers are used as structure-directing agents for the production of superparamagnetic nanostructured material. A block copolymer solution containing an amphiphilic block copolymer is formed. A sol-gel precursor is formed by hydrolyzing and condensing a silicate precursor solution. An iron precursor is added to either the block copolymer solution or the sol-gel precursor. The sol-gel precursor is mixed with the block copolymer solution to form a hybrid inorganic nanostructured material. Solvent is then removed resulting in the formation of individual nanostructured material which is calcinated to form the superparamagnetic nanostructured material. The resulting superparamagnetic nanostructured material may be in the shape of a sphere, a cylinder, lamellae, or a mesoporous structure.
