objective(s): in a new approach, following the development in metal oxide chemistry, the ibuprofen as low water soluble nonsteroidal anti-inflammatory drug diffused into synthetic sol-gel derived nano porous g-alumina by an impregnation method in order to increase the solubility and control the drug release in physiological environment. methods: sol-gel method was utilized for the fabrication o...

Clinical applications of cancer nanomedicines have been challenged by tumor heterogeneity and patient variation. CT imaging nanoparticle extravasation into solid tumors upon intravenous administration, enabled this novel contrast, provides critical insights on characteristics potential for disposition drug delivery prior to treatment. This is reported Xiuling Lu co-workers in article number 220...

A "cluster-bomb"-like lipid-dendrimer nanoassembly synergizes the functions of its components and thereby efficiently accomplishes the drug delivery cascade for high efficacy in treating cancer. The nanoassembly successfully circulates in the blood and accumulates in the tumor. Once in the tumor, it releases small dendrimers that act like "bomblets", enabling tumor penetration, cell internaliza...

Systemic drug delivery to solid tumors involving macromolecular therapeutic agents is challenging for many reasons. Amongst them is their chaotic microvasculature which often leads to inadequate and uneven uptake of the drug. Localized drug delivery can circumvent such obstacles and convection-enhanced delivery (CED)--controlled infusion of the drug directly into the tissue--has emerged as a pr...

Because of the particular characteristics of the tumor microenvironment and tumor angiogenesis, it is possible to design drug delivery systems that specifically target anti-cancer drugs to tumors. Most of the conventional chemotherapeutic agents have poor pharmacokinetics profiles and are distributed non-specifically in the body leading to systemic toxicity associated with serious side effects....

Introduction: Immunotherapy-based approaches for cancer treatment are of increasing clinical interest. Principles of drug delivery and the emerging field of material design for immunomodulation might hold significant promise for novel approaches in cancer immunotherapy since biomaterials engineering strategies enable enhanced delivery of immune modulatory agents to tissues and cells of the immu...

Hypoxia, a hallmark of malignant tumors, often correlates with increasing tumor aggressiveness and poor treatment outcomes. Due to a lack of vasculature, effective drug delivery to hypoxic tumor regions remains challenging. Signaling through the chemokine SDF-1α and its receptor CXCR4 plays a critical role in the homing of stem cells to ischemia for potential use as drug-delivery vehicles. To h...

Enzyme-responsive, hybrid, magnetic silica nanoparticles have been employed for multifunctional applications in selective drug delivery and intracellular tumor imaging. In this study, doxorubicin (Dox)-conjugated, enzyme-cleavable peptide precursors were covalently tethered onto the surface of uniform silica-coated magnetic nanoparticles through click chemistry. This enzyme-responsive nanoparti...

Introduction: Targeted drug delivery systems are nanoscale drug carrier molecules designed for improving the communication of cellular and molecular components and biodistribution of tumour targeted drug (chemo) therapeutics. Nanomaterials are generally clusters of molecules, atoms and molecular fragments into extremely small size particles (1-100 nm) in nature. Nanomaterials engineered as self...
