Literature Review from the year 2022 in the subject Veterinary medicine, , course: Nanotechnology, language: English, abstract: The objective of this seminar paper is to review the application of nanotechnology on smart drug delivery system, in animal disease treatment and diagnosis, animal breeding and reproduction and also chicken product. Nanotechnology is an exciting and rapidly emerging technology allowing us to work at the molecular level, often atom by atom, to create and manipulate tools, materials and functional structures that have nanometer dimensions. It has the potential to have greats impact on diagnosis and treatment of animals. Unique size dependent properties of nanoparticles have numerous diagnostic applications such as diagnostic biosensors, imaging nanoprobes for magnetic resonance imaging contrast agents. Using nanotechnology multifunctional nanomaterial s can be designed to image a specific organ, target tissue, access deep molecular targets and provide drugs at controlled release. Great advances have been and are being made in nanobiochip materials, nanoscale biomimetic materials, nanomotors, nanocomposite materials, interface biomaterials and nanobiosensors with enormous prospect in veterinary medicine application. It is a research and development aimed at understanding and working with seeing, measuring and manipulating at the atomic, molecular and supramolecular levels. This correlates to length scales of roughly 1 to 100 nanometers. At this scale, the physical, chemical and biological properties of materials differ fundamentally and often unexpectedly integrated sensing, monitoring and controlling system could detect the presence of disease and notify the farmer and veterinarian to activate a targeted treatment delivery system. This is possible with nanotechnology and could permit a wide range of advances in the field of agriculture, animal and veterinary sciences such as conversion of agricultural and food wastes to energy and other useful by-products through enzymatic nanobioprocessing, development in reproductive sciences, breeding managements, disease prevention and treatment in animals and public health. Applications of nanotechnology and nanoparticles in food, animal breeding and animal productivity such as in meat production, milk production are emerging rapidly. It used to create materials and change structure, enhanced quality and texture of foodstuffs at the molecular level. This technology has a major impact on production, processing, transportation, storage, traceability, safety and security of food.
