The invention relates to a process for the preparation of a product comprising one or more nanoparticles of calcium phosphate (CaP-NP) with negative surface charge having a ζ-potential in the range from −41.0 mV to −27.0 mV comprising the steps of: a) maintaining a mixture having a pH in the range from 7 to 10 and comprising an aqueous solution of calcium, an aqueous solution of phosphate and a solution of citrate ions at a temperature in the range from 20° C. to 40° C. for a time in the range from 30 seconds to 10 minutes; b) removing non-reacted ions from the solution of step a), thus obtaining a suspension of one or more nanoparticles of calcium phosphate (CaP-NP); c) recovering the product of one or more nanoparticles of calcium phosphate (CaP-NP) from the suspension of step b). In an advantageous embodiment, the process of the invention provides, in the mixture of step a), also an aqueous solution of one or more therapeutic/diagnostic compounds. The product of the invention may be used as a vehicle for one or more diagnostic/therapeutic compounds for the treatment of cardiovascular diseases through inhalation administration.

Functionalized single walled or multi-walled carbon nanotubes (f-CNTs) can be delivered into mammals to targeted organs, such as the kidney and the liver. These f-CNTs may be non-covalently linked or covalently linked to therapeutic agents. In particular, the application delivers carbon nanotube-therapeutic agent conjugates to a target organ, thereby preventing or reducing damages to the organ caused by other agents or procedure.

The present invention relates to compositions comprising an anionic polymer, such as hyaluronate or alginate, a cation such as calcium, an anion such as phosphate, and nucleic acids such as siRNA for the SPARC gene. The compositions are used for delivery of nucleic acids to cells to thereby regulate gene expression and treat diseases such as ocular fibrosis disorders.

Provided is a nanogel exhibiting anticoagulation and antioxidation activities, including a graphene-like nanosheet and a polysaccharide, which are complexed to form a cross-linked supramolecular structure. Also provided is a method of preparing the nanogel, including carbonizing the polysaccharide by dry heating. By the heating process, at least a portion of the polysaccharide is conversed into the graphene-like nanosheet, thereby forming a graphene-like nanosheet-embedded phenolic-polysaccharide nanogel that has exceptional polyphenolic structure and high binding affinity toward thrombin. Further provided is a method of preventing or treating a disease or a condition susceptible to amelioration by anticoagulants or antioxidants by using the nanogel.
