Cytotoxicity of paclitaxel loaded and surface coated poly methacrylic acid-PEG-chitosan based nanoparticles on oestrogen positive breast cancer cells (MCF7) / Noor Farina Nazli

Cancer is a class of diseases which is characterized by uncontrolled division of abnormal cells in the body. It can be divided into two major types, which is benign and malignant tumour. Since conventional paclitaxel formulation using Cremophor­ ethanol (CrEL) is associated with adverse effects, new...
