Nanotechnology manages the investigation of littler structures with a size range between 0.1 to 100 nm. It covers different regions like biophysics, atomic science, and bioengineering and sub strengths of medication, for example, cardiology, ophthalmology, endocrinology, oncology, immunology and so forth... Pharmaceutical Nanotechnology applies the techniques and standards of Nanoscience and Nano medication. Pharmaceutical nanotechnology is currently settled as specific region for medication conveyance, diagnostics, prognostic and treatment of ailments through its Nano-designed apparatuses.

Nanomedicine is the next wave of advancements in the healthcare space. Nano medicine is nanotechnology focused on medical intervention at the molecular scale for repair of tissues and treatment of disease. This field combines the expertise of medicine, mathematics, biology, engineering, chemistry, and computer science for the creation of devices for human application. Today, Nano medicines are used globally to improve the treatments and lives of patients suffering from a range of disorders including ovarian and breast cancer, kidney disease, fungal infections, elevated cholesterol, menopausal symptoms, multiple sclerosis, chronic pain, asthma and emphysema. The Nano medicines can play an important role in ensuring enough of the drug enters the body, that drug that does enter stays in the body for long periods and is targeted specifically to the areas that need treatment.

Nanomaterials are defined as materials composed of unbound particles or as particles in an aggregate or agglomerate state with one or more external dimensions with a size ranging from 1 to 100nm. Nanomaterials are chemical substances or materials that are manufactured and used at a very small scale. Nanomaterial’s are developed to exhibit novel characteristics compared to the same material without nanoscale features, such as increased strength, chemical reactivity or conductivity.

Two main approaches are used in nanotechnology. In the "bottom up" approach, materials and devices are built from molecular components which assemble themselves chemically by principles of molecular recognition. In the "top down" approach, Nano-objects are constructed from larger entities without atomic-level control.

Nanorobotics is the technology that is used to create machines whose sizes are in nanometer. Mainly Nano robots are of high significance in the research and development phase. The main purpose of Nano robots is to carry out a specific task redundantly and with precision at nanoscale dimensions. Nano robots are used in medical field to destroy cancer cells and in the Field of Hematology, ophthalmology. Nano robots will also have useful applications for biohazard defense, including improving the response to epidemic disease. Nanorobotics may also reduce contamination and provide successful screening for quarantine. In the event of an influenza epidemic for example, increased concentrations of alpha-NAGA enzyme in the blood stream could be used as a biomarker for the influenza infection.

The Nanotechnology is quick picking up footing over a scope of ventures, from agribusiness to water treatment to vitality stockpiling. Today, nanotechnology is one of the most progressive, front line regions of logical examination and it keeps on progressing at stunning rates. From researchers at innovation centered organizations and foundations to understudies seeking after a nanotechnology degree, pioneers in nanotechnology are making the most recent developments in this field.

Materials science is important for the development of technology and has been or thousands of years. Different materials have different strengths and weaknesses and are used for different purposes. Materials Science and Engineering is the study of all materials, from those we see and use every day such as a glass or a piece of sport equipment to those used in aerospace and medicine, through that understanding how materials work, can create new materials for new applications as well as develop existing materials to improve performance. They can control the structure of a material, from an atomic level up.

Nanostructures refer to materials or structures that have at least one dimension between 1 and 100 nm. The various sub-fields of nanotechnology focus on the creation, characterisation and application of Nano structures. Nanostructures are fabricated by methods as simple as solution processing, and as complicated as advanced lithography. In addition to extensive efforts in the fabrication of nanostructures, current research and development of nanostructures also focus on the investigation of fundamental material properties, including mechanical, electrical, and optical properties at the nanoscale, and the development of novel applications in a broad range of engineering fields.
