Nanotechnology is the atomic and molecular engineering and manipulation of materials, sometimes down to the scale of a single atom. Scientists can create new materials with unique and valuable properties by controlling the nanoparticles' size, shape, and composition. Nanotechnology has had a significant impact in various industries, including electronics, medicine, energy production, and agriculture. Nanoencapsulation is the process of enclosing one or more substances within a protective coating of nanometer-sized particles. The advantages of nanoencapsulation include protection of the encapsulated material from harsh environments, delivery of drugs to specific target tissues, and prolongation of the drug's activity. Nanoencapsulation has been used to deliver various drugs and other therapeutic agents, including chemotherapy drugs, peptides, proteins, and genes.
