To overcome the drawback of drug non-selectivity in traditional chemotherapy, the construction of multifunctional targeting drug delivery systems is one of the most effective and prevailing approaches. The intratumoral anti-angiogenesis and the tumor cell-killing are two basic approaches in fighting tumors. Herein we report a novel tumor vascular-targeting multidrug delivery system using mesopo...

Supramolecularly constructing multifunctional platform for drug delivery is a challenging task. In this work, we propose a novel supramolecular strategy "drug chaperone", in which macrocyclic amphiphiles directly coassemble with cationic drugs into a multifunctional platform and its surface is further decorated with targeting ligands through host-guest recognition. The coassembling and hierarch...

Multifunctional mesoporous silica nanoparticles (MSNs) are good candidates for multimodal applications in drug delivery, bioimaging, and cell targeting. In particular, controlled release of drugs from MSN pores constitutes one of the superior features of MSNs. In this study, a novel drug delivery carrier based on MSNs, which encapsulated highly sensitive F magnetic resonance imaging (MRI) contr...

In this paper, a novel, multifunctional polymer nanocarrier was designed to provide adequate volume for high drug loading, to afford a multiregion encapsulation ability, and to achieve controlled drug release. An amphiphilic, triblock polymer (ABC) with hyperbranched polycarbonsilane (HBPCSi) and β-cyclodextrin (β-CD) moieties were first synthesized by the combination of a two-step reversible a...

Medically, the oil-in-water nanosized emulsions are used mainly as delivery carriers for lipophilic drug molecules which show therapeutic activity when administered via parenteral, ocular and transdermal routes. To extract multifunctional activities, the nanosized emulsions containing neutral, anionic and cationic charges over dispersed oil droplets are designed with the help of variety of exci...

The oral route is the best and most popular for administration of drugs in systemic circulation. There are number which given through route. Gastro-retentive drug delivery system very important system. gastro-retentive prolonged time git also improve their bioavailability. These widely used site specific treatment disorders diseases. approaches gastro retentive such as floating system, mucoadhe...
