Voronov plans to organize a symposium at INCFA’13 conference

Voronov plans to organize symposium “Nanotechnology in Anticancer Research” at the 4th International Conference on Nanotechnolgy: Fundamentals and Applications (ICNFA’13) held at the University of Toronto, Toronto, On in August 2013.

ICNFA is a series of international conferences held yearly. These conferences focus on all aspects of nanotechnology. The aim of ICNFA conferences is to bring together an international community working in the field of nanotechnology, and to foster an environment conducive to present advances in this field.

Cancer nanotechnology is a rapidly growing field that contributes remarkably to cancer treatments by developing novel therapeutic and diagnostic strategies. Materials at a nanometer scale are engineered as platforms for effective targeted delivery of drugs, and imaging agents that overcome many biological and biophysical barriers.

The examples of cancer- related nanomodalities include liposomes, polymeric micelles, polymer-drug conjugates, carbon nanotubes, dendrimers, inorganic particulates such as quantum dots, paramagnetic nanoparticles, contrast agents for magnetic resonance imaging, etc.

Materials at a nanoscale have several advantages compared to small molecule-based therapy such as higher payload capacity, prolonged blood circulation times, reduced toxicity to healthy tissues, and improved anti-tumor efficiency.

The scope of “Nanotechnology in Anticancer Research” symposium is to provide most up-to-date development of novel nanotechnology-based approaches towards cancer treatment to the nanotechnology-field scientific community. Special emphasis will be given to integrated nanotherapeutic systems (including theranostic nanomedicine) and multifunctional designs with cancer targeting, imaging and controlled release properties.
