Nanotechnology is the manipulation of material on an atomic and molecular scale; by changing its physical, chemical and biological properties to produce novel materials, devices, and systems. Nanomaterials exhibit remarkable characteristics such as high surface to volume ratio, catalytic activity, and biocompatibility which make them suitable for various biomedical applications. Nanotechnology have prospective to improve the whole healthcare process for patient; starts from diagnosis to treatment and follow-up monitoring. Medical diagnosis based on nanotechnology provides two major advantages: rapid testing and early diagnosis. The potential contributions of c in the medical diagnosis are extremely broad and improve traditional diagnostic tools and methods in the field of clinical diagnosis, imaging and electro- diagnosis. Emerging modalities such as biochip, microarray, nanobarcode, micro-electromechanical systems, lab on chip and nanobiosensor have revolutionized the field of medical diagnosis. Nanoscale materials and nano-enabled techniques are used for diagnosis of various diseases such as cardiovascular diseases, cancer, diabetes, infectious disease, musculoskeletal and neurodegenerative disease etc. Among all medical applications of nanotechnology, nanobiosensor especially enzyme nanobiosensor are sensitive, reliable, robust, reproducible and cost effective diagnostic tool to meet the requirements of healthcare.
