Nanotechnology is an emerging field in applied sciences which combines a few disciplines such as physics and chemistry for various applications including electronics [1], food manufacturing and packaging [2], and wastewater treatment [3]. Nanotechnology is often referred to as the particles or matters within the range of 1 to 100 nm and the term “nanos” was originated from the Greek word which means dwarf [4, 5]. In recent years, incorporation of nanotechnology in medical and pharmaceutical field, or better known as nanomedicine, has been given high expectation on its potential as diagnostic tools and novel therapies. Based on the definition from European Science Foundation (ESF 2004), nanomedicine particularly means the science and technology of diagnosing, treating, and preventing disease and traumatic injury, of relieving pain, and of preserving and improving human health, using molecular tools and molecular knowledge of the human body. The application of nanomedicine can be further classified into five disciplines, namely analytical tools, nanoimaging, nanomaterials and nanodevices, novel therapeutics and drug delivery system, and clinical,
