Here, we describe a bone morphogenetic protein-2 (BMP-2) nanocarrier based on glycyrrhetinic acid (GA)-poly(ethylene glycol) (PEG)-b-poly(l-lysine) (PLL). A protein nanocarrier was synthesized, characterized and evaluated as a BMP-2 delivery system. The designed nanocarrier was synthesized based on the ring-opening polymerization of amino acid N-carboxyanhydride. The final product was measured ...

A water-soluble, core-multishell (CMS) nanocarrier based on a new hyperbranched polyester core building block was synthesized and characterized towards drug transport and degradation of the nanocarrier. The hydrophobic drug dexamethasone was encapsulated and the enzyme-mediated biodegradability was investigated by NMR spectroscopy. The new CMS nanocarrier can transport one molecule of dexametha...

For early cancer diagnosis and treatment, a nanocarrier system is designed and developed with key components uniquely structured at nanoscale according to medical requirements. For imaging, quantum dots with emissions in the near-infrared range (∼800 nm) are conjugated onto the surface of a nanocomposite consisting of a spherical polystyrene matrix (∼150 nm) and the internally embedded, high fr...

In the current study, the design, synthetic feasibility and biochemical characterization of biodegradable peptidic PEG-based nanocarriers are described. The components were selected to influence the body elimination pathway upon nanocarrier biodegradation. Two prototypical nanocarriers were prepared using non-PEGylated and PEGylated peptidic cores [CH(3)CO-(Lys-betaAla-betaAla)(X)-Cys-CONH(2) (...

A programmed supramolecular nanocarrier was developed for multistage targeted photodynamic therapy. This smart nanocarrier exhibited enhanced cellular uptake and controlled mitochondria targeting, as well as an excellent photodynamic therapeutic effect after light irradiation.

A novel triblock poly(amido amine)-poly(ethylene glycol)-poly-l-lysine (PAMAM-PEG-PLL) nanocarrier was designed, synthesized, and evaluated for the delivery of siRNA. The design of the nanocarrier is unique and provides a solution to most of the common problems associated with the delivery and therapeutic applications of siRNA. Every component in the triblock nanocarrier plays a significant rol...

To develop a feasible and efficient nanocarrier for potential clinical application, a series of photo and redox dual responsive reversibly cross-linked micelles have been developed for the targeted anticancer drug delivery. The nanocarrier can be cross-linked efficiently via a clean, efficient, and controllable coumarin photodimerization within the nanocarrier, which simplify the formulation pr...

Recent developments in nanotechnology have provided new tools for both cancer imaging and treatment. The functionalization of the nanocarrier based drugs using biological ligands allows increasing specificity of drug targeting enhancing efficacy and reducing side effects. In this paper some current nanocarrier based drugs are described and the principles for their functionalization in cancer tr...

objective(s): the introduction of nucleic acids into cells for therapeutic objectives is significantly hindered by the size and charge of these molecules and therefore requires efficient vectors that assist cellular uptake. for several years great efforts have been devoted to the study of development of recombinant vectors based on biological domains with potential applications in gene therapy....
