Article
Cationic nanoparticles have superior transvascular flux into solid tumors: Insights from a mathematical model
(2013)Despite their great promise, only a few nanoparticle formulations have been approved for clinical use in oncology. The failure of nano-scale drugs to enhance cancer therapy is in large part due to inefficient delivery. To ...

Article
Combining two strategies to improve perfusion and drug delivery in solid tumors
(2013)Blood perfusion in tumors can be significantly lower than that in the surrounding normal tissue owing to the leakiness and/or compression of tumor blood vessels. Impaired perfusion reduces oxygen supply and results in a ...

Article
Delivering nanomedicine to solid tumors
(2010)Recent advances in nanotechnology have offered new hope for cancer detection, prevention, and treatment. While the enhanced permeability and retention effect has served as a key rationale for using nanoparticles to treat ...

Article
Delivery of molecular and nanoscale medicine to tumors: Transport barriers and strategies
(2011)Tumors are similar to organs, with unique physiology giving rise to an unusual set of transport barriers to drug delivery. Cancer therapy is limited by nonuniform drug delivery via blood vessels, inhomogeneous drug transport ...

Design considerations for nanotherapeutics in oncology
(2015)Nanotherapeutics have improved the quality of life of cancer patients, primarily by reducing the adverse effects of chemotherapeutic agents, but improvements in overall survival are modest. This is in large part due to the ...

Multiresponsive polymer conetworks capable of responding to changes in pH, temperature, and magnetic field: Synthesis, characterization, and evaluation of their ability for controlled uptake and release of solutes
(2012)This study deals with the preparation of novel multiresponsive (magnetoresponsive, thermoresponsive and pH-responsive) nanocomposite conetworks consisting of oleic acid-coated magnetite nanoparticles (OA•Fe 3O 4), ...

Article
Multistage nanoparticle delivery system for deep penetration into tumor tissue
(2011)Current Food and Drug Administration-approved cancer nanotherapeutics, which passively accumulate around leaky regions of the tumor vasculature because of an enhanced permeation and retention (EPR) effect, have provided ...

Article
The role of mechanical forces in tumor growth and therapy
(2014)Tumors generate physical forces during growth and progression. These physical forces are able to compress blood and lymphatic vessels, reducing perfusion rates and creating hypoxia. When exerted directly on cancer cells, ...

Sonic-hedgehog pathway inhibition normalizes desmoplastic tumor microenvironment to improve chemo- and nanotherapy
(2017)Targeting the rich extracellular matrix of desmoplastic tumors has been successfully shown to normalize collagen and hyaluronan levels and re-engineer intratumoral mechanical forces, improving tumor perfusion and chemotherapy. ...
