We report a novel approach to efficiently package and deliver siRNAs with low generation dendrimers by using Au nanoparticles as a “labile catalytic” packaging agent. The Au nanoparticles helped low generation dendrimers to package siRNA but are not included in the final siRNA complexes. Therefore, the potential toxic problem accompanied with the Au nanoparticles can be easily solved by selecti...

in  this  work,  a  new  hybrid  organometallic-inorganic  hybrid nanomaterial was prepared by immobilization of acetyl ferrocene on the  surface  of magnetite  nanoparticles. covalent  grafting of silica coated magnetite nanoparticles (scmnps) with 3-aminopropyl triethoxysilane gave aminopropyl-modified magnetite nanoparticles (ampscmnps). then, schiff base condensation  of ampscmnps with acet...

Biomorphs are a unique class of self-organised silica–carbonate mineral structures with elaborate shapes. Here we report first approaches to modify these complex inorganic architectures through silane chemistry, binding of nanoparticles, and organic polymerisation. This leads to functional nanostructures in which the complexity of the originally inorganic template is preserved, and offers new d...

Nanotechnology has enabled the development of many alternative anti-cancer approaches, such as thermal therapies, which cause minimal damage to healthy cells. Current challenges in cancer treatment are the identification of the diseased area and its efficient treatment without generating many side effects. Image-guided therapies can be a useful tool to diagnose and treat the diseased tissue and...
