Selenium methionine (Se Met) is an essential micronutrient required for normal body function and is associated with additional health benefits. However, oral administration of Se Met can be challenging due to its purported narrow therapeutic index, low oral bioavailability, and high susceptibility to oxidation. To address these issues, Se Met was entrapped in z e i n-coated nanoparticles made from chitosan using an ionic gelation formulation. The high stability of both the Se Met and s e l e n o methionine nanoparticles (Se Met-NPs) was established using cultured human intestinal and liver epithelial cells, rat liver homogenates, and rat …

Combination Strategies For Targeted Delivery Of Nanoparticles For Cancer Therapy, Zhonglie He, Kangze Liu, Hugh Byrne, Patrick Cullen, Furong Tian, James Curtin

Pharmaceuticals, and more recently biopharmaceuticals, have become the mainstay for antineoplastic treatments in combination with surgical interventions and radiation therapy. In recent years, advances have been made in the development of nano-technological interventions for the treatment of cancer alone or in combination with existing therapeutic modalities. Nanotechnology used for therapeutic drug delivery and sensitization of photodynamic, sonodynamic and radiotherapy are now being tested in preclinical and clinical trials for the treatment of cancer. This article will review the current state of the art for nanotechnology therapies with an emphasis on targeted drug delivery and the observed and likely benefits when …

Cancer Nanotheranostics: What Have We Learned So Far?, Joao Conde, Furong Tian, Jesus M. De La Fuente, Pedro V. Baptista

After a quarter of century of rapid technological advances, research has revealed the complexity of cancer, a disease intimately related to the dynamic transformation of the genome. However, the full understanding of the molecular onset of this disease is still far from achieved and the search for mechanisms of treatment will follow closely.

It is here that Nanotechnology enters the fray offering a wealth of tools to diagnose and treat cancer. Today, Nanotechnology is a burgeoning field that is helping to address critical global problems from cancer treatment to climate change. In fact, Nanotechnology is everywhere and is everyday practice …
