This book on nanoformulation of cancer drugs provides a naotechnology based practical approach towards solving the current problems of uncontrollable drug delivery and adverse effects associated with systemic chemotherapy. The research is applied on common chemotherapy drugs like ‘Paclitaxel'' and ‘Tamoxifen'' but not limited to therapeutic agents, as nanoformulation of ‘Gadolinium'', a MRI contrast agent is also described here. This work was performed at the nanotechnology labs of LA Tech University''s well known "Institute for Micromanufacturing" (IFM),USA, under the guidance of one of the pioneers in this field, Dr. Yuri M. Lvov. Part of this work was featured as the cover story in 7th issue of the international pharmaceutical magazine "Pharma Focus Asia" as "R&D @ NANO LEVEL" in 2008 and also published in peer reviewed journals including the well celebrated drug delivery medical journal "Journal of Controlled Release." This research counted towards a US Patent application and received national level funding. In the April 2009 issue of IFM Newsletter, the author has been quoted as "A person who is a brilliant professional both in engineering and medicine."
