Selective targeting and degradation of doxorubicin-loaded folate-functionalized DNA nanocages

Size-selective shell cross-linked interior functionalized siloxane nanocages.

A new structure, consisting of a shell cross-linked, 2 nm size siloxane nanocage containing propylamine groups tethered to the interior face of the shell was synthesized, starting with micelles of the surfactant molecule, (triethoxysilyl)propylcetylcarbamate. After hydrolysis of the ethoxysilyl groups and condensation and capping of the silanols to form a cross-linked, one-atom-layer-thick silo...

cytotoxicity of doxorubicin loaded in folate-targeted micelles of dextran/retinoic acid in acute leukemia

Cellular interactions of doxorubicin-loaded DNA-modified halloysite nanotubes.

Halloysite nanotube (HNT)-based supramolecular complexes are synthesized and evaluated with respect to their cytotoxicity and effects on cellular structures. As HNTs are water-insoluble, DNA is applied for wrapping the surface of HNTs to enhance their water-dispersibility. To investigate the potential of DNA-wrapped HNTs (HD) as a promising drug delivery carrier, doxorubicin (DOX) is introduced...

Functionalized Magnetic Nanoparticles for Selective Targeting of Cells

Magnetic metal oxide nanoparticles were conjugated to single stranded DNA (ssDNA), and Cytosin-phosphatidyl-Guanosin oligonucleotide (CpG ODN) to detect and activate Toll-like (TLR9) receptors in cells and to follow nanoparticle cellular trafficking by different ways of imaging while at the same time serving as a drug carrier system. By virtue of their magnetic properties these nanoparticles ma...

Doxorubicin Loaded DNA Aptamer Linked Myristilated Chitosan Nanogel for Targeted Drug Delivery to Prostate Cancer

Recently, specific attention has been paid to aptamers, short DNA or RNA, as a tool for cancer diagnosis and therapy. In the present study MCS nanogels were prepared by Myristate: chitosan at 1:9 ratio and were characterized by several techniques. A selected ssDNA aptamer(Apt) capable of detecting LNCaP cells was linked to Myristilated chitosan nanogels (Apt-MCS) by glutaraldehyde and loaded wi...
