Nanotherapeutic strategy is well recognized as the therapeutic approach of the future. Numerous reports have demonstrated the use of nanoparticulate drug carriers for the development of targeted nanotherapeutics by, for instance, incorporation of a moiety that specifically targets certain diseased cells. However, systematic investigation of this aspect has been inadequate, especially with regar...

Combination of doxorubicin with sorafenib (SF) was reported to be a promising strategy for treating hepatocellular carcinoma (HCC). In this study, we designed a reduction-responsive supramolecular nanosystem based on poly (ethylene glycol)-β-cyclodextrin (PEG-CD) and a disulfide-containing adamantine-terminated doxorubicin prodrug (AD) for efficient co-delivery of doxorubicin and sorafenib. PEG...

This study evaluated in vitro and in vivo a colloidal nanosystem with the potential to deliver drugs to the ocular surface. This nanosystem, liposome-chitosan nanoparticle complexes (LCS-NP), was created as a complex between liposomes and chitosan nanoparticles (CS-NP). The conjunctival epithelial cell line IOBA-NHC was exposed to several concentrations of three different LCS-NP complex to dete...

Cancer metastasis is the leading reason for the high mortality of breast cancer. Herein, we report on a pH-responsive host-guest nanosystem of succinobucol (PHN) with pH-stimuli controlled drug release behavior to improve the therapeutic efficacy on lung metastasis of breast cancer. PHN was composed of the host polymer of β-cyclodextrin linked with multiple arms of N,N-diisopropylethylenediamin...

We calculate and model the microscopic dielectric response function for quantum dots using first principle methods. We find that the response is bulklike inside the quantum dots, and the reduction of the macroscopic dielectric constants is a surface effect. We present a model for the microscopic dielectric function which reproduces well the directly calculated results and can be used to solve t...

Glyco-gold nanoparticles combine in a single entity the peculiar properties of gold nanoparticles with the biological activity of carbohydrates. The result is an exciting nanosystem, able to mimic the natural multivalent presentation of saccharide moieties and to exploit the peculiar optical properties of the metallic core. In this review, we present recent advances on glyco-gold nanoparticle a...
