Metals, non-metals, bio-ceramics, and many polymeric materials are used to produce nanoparticles of the respective materials. These are functional in producing liposomes, PEG and many more. Due to their small size nanoparticles has found to be interacting with human bodies same like of gases. Nanoparticles of the same composition can display behavioral differences when interacting with different environments.  Nanoparticles can enter the human body via inhalation, ingestion, or skin contact. The range of pathologies related to exposure to nanoparticles encompasses  respiratory and even several organs and leads to diseases. Accurate in vitro assessment of nanoparticle cytotoxicity requires a careful selection of the test systems. Due to high adsorption capacity and optical activity, engineered nanoparticles are highly potential in influencing classical cytotoxicity assays.

One of the exciting features of nanotechnology is its utility in the field of Nano medicine, therapeutics, and medical devices . When these small size materials are introduced into biological systems, their extremely small size and their unique Nano scale properties make it possible to use them as delivery vectors and probes for biological diagnostics, bioimaging and therapeutics. In fact, when size decreases, the surface area to volume ratio of materials becomes very large, so that a vast suitable surface is available for chemical interactions with biomolecules. This critically implied that nanotechnology is facing a transition into the tangible advancement of human therapeutics. Recently, There are multiple clinical trials of nanomaterials have done; both for therapeutics and for medical devices.

Nanoscience and nanobiotechnology are at the head of contemporary research. A multidisciplinary scientific education is crucial to provide industry and research institutes with top quality experts who have a generic background in the different subdisciplines such as electronics, physics, chemistry, material science, biotechnology, and at the same time be experts in one particular field. This is what is offered in this master programme. Nanotechnology is the application of nanoscience leading to the use of new nanomaterials and nanosize components in useful products. Nanotechnology will eventually provide us with the ability to design custom-made materials and products with new enhanced properties, new nanoelectronics components, new types of “smart” medicines and sensors, and even interfaces between electronics and biological systems. ortant properties of materials, such as the electrical, optical, thermal and mechanical properties, are determined by the way molecules and atoms assemble on the nanoscale into larger structures. Moreover, in nanometer size structures these properties often different then on macroscale, because quantum mechanical effects become important.

Veterinary science helps human health through the monitoring and control of zoonotic disease (infectious disease transmitted from non-human animals to humans), food safety, and indirectly through human applications from basic medical research. They also help to maintain food supply through livestock health monitoring and treatment, and mental health by keeping pet’s healthy and long living. Veterinary scientists often collaborate with epidemiologists, and other health or natural scientists depending on type of work. Ethically, veterinarians are usually obliged to look after animal welfare. Veterinary research includes research on prevention, control, diagnosis, and treatment of diseases of animals and on the basic biology, welfare, and care of animals. Veterinary research transcends species boundaries and includes the study of spontaneously occurring and experimentally induced models of both human and animal disease and research at human-animal interfaces, such as food safety, wildlife and ecosystem health, zoonotic diseases, and public policy.
