    摘要： Fluorescent activatable probes for imaging biological processes and disease detection in vitro and in vivo. There is also described a method for detecting the presence of an enzyme. A sample is contacted with a nanoparticle including a monomer, at least one cleavable spacer comprising at least one fluorescence activation site, and at least two dyes of at least two types. The cleavable spacer is attached at one end to the nanoparticle. The at least two types comprise an energy donor type and an energy acceptor type. At least one dye of one type is embedded in the nanoparticle and the cleavable spacer has at least one dye of the other type attached. The at least two dyes comprise at least one matched pair capable of fluorescence resonance energy transfer. Fluorescence is detected by exposing the sample to a light source, and detecting emitted light with a detector.

    摘要： Disclosed is a fire extinguishing composition of copper salts, which comprises a compound of copper salts and a fire retardant component with the content of 30 wt %--95 wt % for the former and 5 wt %-70 wt % for the latter respectively. A pyrotechnic agent in the composition serves as heat source and power source, and through being ignited, the pyrotechnic agent is burnt to generate high temperature to enable the composition to perform decomposition reaction so that a large quantity of the resulting fire extinguishing substances can be spouted out with the pyrotechnic agent to achieve an object of fire extinguishing. The fire extinguishing composition of copper salts can decrease the quantity of heat released by combustion of the pyrotechnic agent rapidly and efficiently, thus greatly reducing the nozzle temperature of a fire extinguishing apparatus and a sprayed substance, avoiding use of a complicated cooling system of the fire extinguishing apparatus, and also eliminating the danger of a secondary fire. the fire extinguishing composition releases a great deal of an effective fire extinguishing substance at the moment of being heated, through the synergistic effect of various particles, the fire extinguishing time is greatly shortened.

    摘要： Non-viral vectors for delivering agents to a site within the body of an animal comprise a biocompatible nanoparticle conjugated to an avidin/biotin complex and a water soluble linear polymer comprising multiple binding sites. The agents to be delivered are conjugated to each of the multiple binding sites, thereby increasing the loading capacity of the system. Where the agents comprise siRNA, each biotin/avidin complex may carry greater than four siRNA. The biocompatible nanoparticle may also comprise a fluorescent dye for in vivo imaging.
