Liposomes are spherical, self-closed structures formed by lipid bilayers that can encapsulate drugs and/or imaging agents in their hydrophilic core or within their membrane moiety, making them suitable delivery vehicles. We have synthesized a new liposome containing gadolinium-DOTA lipid bilayer, as a targeting multimodal molecular imaging agent for magnetic resonance and optical imaging. We sh...

This paper describes new superparamagnetic nanoparticles bearing dextran-grafted porphyrins with effective cellular uptake properties. They average 110 nm in diameter and are composed of a 5 nm iron oxide core coated with protoporphyrin-grafted dextrans. These particles show good magnetic properties, are avidly incorporated into cultured cancer cell lines, and thus present a great potential for...

As an alternative therapeutic treatment to reduce or eliminate the current side effects associated with advanced prostate cancer (PCa) chemotherapy, a multifunctional double-receptor-targeting iron oxide nanoparticles (IONPs) (luteinizing hormone-releasing hormone receptor [LHRH-R] peptide- and urokinase-type plasminogen activator receptor [uPAR] peptide-targeted iron oxide nanoparticles, LHRH-...

A current advance in nanotechnology is the selective targeting of therapeutics by external magnetic field-guided delivery. This is an important area of research in medicine. The use of magnetic forces results in the formation of agglomerated structures in the field region. The transport characteristics of these agglomerated structures are explored. A nonintrusive method based on in situ light-s...

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...

This study focuses on the development of theranostic, dual drug-loaded nanocarriers to propose a proof-of-principle therapeutic approach in treatment pancreatic ductal adenocarcinoma (PDAC). The nanoconstructs consist core zinc oxide nanocrystals doped with gadolinium, useful as potential contrast agent magnetic resonance imaging applications. After functionalizing their surface amino-propyl gr...

Patient noncompliance to current tuberculosis (TB) therapy owing to multidrug administration daily leads to treatment failure and emergence of multidrug resistant and extensively drug resistant TB. To avoid the daily dosing, application of nanotechnology is the only viable solution by virtue of sustained release of drugs. Other potential advantages of the system include the possibility of selec...

Introduction: Cancer is a class of diseases characterized by out-of-control cell growth. There are over 100 different types of cancers classified by organ or tissues they affected. In these days, more people die from cancers than from AIDS. Therefore, many efforts are in progress to develop treatments for cancer. The common treatment is chemotherapy but the drugs still lack of the efficacy of s...
