Nanotechnology as a Medicine As modern science learns more and more about the human body and the functions of its various systems material science is delving into the molecular level The marriage of these two fields is considered to be nanotechnology Todays science is working on the design and synthesis of a wide range of nanostructures with specified geometry and surface characteristics in hopes of unlocking all the potential uses of nanotechnology For example tailored nanomaterials could be used in inclusion chemistry and electrochemistry material and biomedical sciences electron microscopy molecular storage and separation technology After researching many potential applications of nanotechnology it is my belief that this new technology is most practical and useful in the medical arena This essay will give an overview of the nanobot and will illustrate concrete examples of how a nanobot could be used inside the human body Nanomachines ranging from a few to a few hundred nanometers in size are used to manipulate systems This manipulation may take place at the cellular level or even the atomic level A suggested name for these nanomachines is assemblers Each assembler will be a nanocomputer with a robotic arm These computers will be programmable with optional instructions for manipulating atoms or molecules The assemblers will also have the ability to replicate themselves making production costs relatively cheap An example of a naturally occurring assembler is the protein-manufacturing ribosome Ribosomes manufacture all the proteins that exist in living cells and are relatively small on the same scale as the suggested assembler They are capable of building almost any protein Each ribosome does this by stringing together amino acids in a precise linear sequence This means that it has some mechanism such as the suggested robotic arm of the assembler to grasp a specific RNA molecule and then chemically bond it to a specific amino acid by using a specific enzyme It also uses this mechanism to manipulate the growing
