Nanotechnology and biotechnology are two of the most promising technologies of the twenty-first century. Nanotechnology is defined as the creation, development, and implementation of materials and technologies with the smallest functional components on a nanoscale size (1 to 100 nm). Biotechnology, on the other hand, is concerned with the metabolic and other physiological changes that occur in biological subjects, such as microorganisms. These microbial activities have opened up new avenues for investigation into novel applications, implying that these two technologies (i.e., nanobiotechnology) can play a critical role in the development and implementation of a wide range of useful tools in the study of life. This concept can be applied to a wide range of scientific domains, including plant biology, organic chemistry, agriculture, the food business, and more. Nanotechnology encompasses a wide range of activities, from extending traditional device physics to wholly new ways based on molecular self-assembly, from discovering novel nanoscale materials to investigating whether we can directly manipulate matter at the atomic scale level. Nanobiotechnology has a wide range of applications in medicine, agriculture, and environmental protection. Many diseases that currently have no therapies may be healed in the future due to nanotechnology.
Nanotechnology's use in medical therapies necessitates a thorough assessment of its risk and safety concerns. All of the issues regarding nanotechnology's protection are referred to as "nanosafety." Despite the fact that nanotechnology has been growing for nearly two decades, it is still regarded as a novel technology, and the health effects of nanomaterials have not been adequately investigated.
