Nanorobotics can perform a wide range of tasks in diagnosis, monitoring, and treating viral diseases. These nanorobots are capable of delivering medicine or drugs to specific sites/targets in the human body. It provides ambulatory care for treating injuries and illness in various areas of applications of nanorobots leveraging the unique properties of materials and devices in the nanoscale dimensions. Nanochemistry is the combination of chemistry and nanoscience. It is associated with the synthesis of building blocks that are dependent on size, surface, shape, and defect properties. Nanochemistry Application areas include engineering, biological, and medical with the field of chemical, materials, and physical as well as science.
