Green-synthesized tellurium nanowires (GREEN-TeNWs) are generated using a biopolymer as a unique reducing agent, purified, and used as a template for the growth of coated palladium nanoparticles (PdNPs) and platinum nanoparticles (PtNPs) on top of the GREEN-TeNWs, in a reaction that can take place in seconds, with no need for high temperature, stirring, or for additional reducing agent. The heterogeneous structure can contain palladium oxide or platinum oxide. The green-synthesized PdNPs-TeNWs (palladium nanoparticles with tellurium nanowires) and PtNPs-TeNWs (platinum nanoparticles with tellurium nanowires) show potential biomedical applications as antibacterial, anticancer, and antioxidant agents, and show low cytotoxicity for healthy human cells.

The present invention relates to a docetaxel albumin nanoparticle pharmaceutical composition, a preparation method therefor, and a use thereof for manufacturing drugs for treating cancer. The pharmaceutical composition comprises docetaxel, albumin and amino acid(s), wherein the weight ratio between albumin and docetaxel is no more than 50, preferably is 20:1 to 1:1, and the weight ratio between amino acid(s) and docetaxel is not less than 0.5, preferably is 1:1 to 20:1.

The presently disclosed subject matter provides methods for continuously generating uniform polyelectrolyte complex (PEC) nanoparticles comprising: flowing a first stream comprising one or more water-soluble polycationic polymers at a first variable flow rate into a confined chamber; flowing a second stream comprising one or more water-soluble polyanionic polymers at a second variable flow rate into the confined chamber; and impinging the first stream and the second stream in the confined chamber until the Reynolds number is from about 1,000 to about 20,000, thereby causing the one or more water-soluble polycationic polymers and the one or more water-soluble polyanionic polymers to undergo a polyelectrolyte complexation process that continuously generates PEC nanoparticles. Compositions produced from the presently disclosed methods and a device for producing the compositions are also disclosed.
