Due to knowledge on nanotechnology, doctors are able to treat various diseases that it was impossible to treat in the yester-years. One of the important roles of nanotechnology is drug delivery.Researchers have developed the nanoparticles that have the capability of delivering vaccines to the body. A variety of bacteria and viruses normally infect human beings through mucosal surfaces. This includes areas such as the reproductive tract, gastrointestinal tract, the lungs, etc (Fisher, 2006). In fighting these pathogens, scientists have developed vaccines that have the capability of establishing a frontline defense at the mucosal surfaces. Service (2005) explains that it is possible to deliver vaccines to the lungs, through the aerosol spray. However, the lungs normally clear the vaccine before they can respond by providing immunity.To solve this problem, medical practitioners are using nanoparticles for purposes of protecting the vaccines for a period that can enable them to develop a strong immunity response. Vaccines that are delivered through this method have the capability of protecting the body against flue or other respiratory diseases or viruses. They also have the capability of preventing sexually transmitted diseases such as human papilloma virus, herpes simplex virus, etc. Furthermore, it is possible to use nanotypes in delivering drugs orally, and this is through a digestive tract. This is an important step in the administration of medicine, because it helps in allowing patients to take drugs. This is as opposes to an injection. On this note, patients have a choice on wether to be injected or to take drug pills in their delivery of drugs. It is important to denote that some patients prefers delivery of drugs through pills, while others normally prefer delivery of drugs through an injection.Furthermore, Roco (2001) explains that nanomedicine is used in therapy. Roco (2001) explains that scientists have come up with nanosponges aimed at absorbing toxins and removing these toxins from the bloodstream of an individual. These nanosponges are polymers, and they have a coating of the membrane of a red blood cell. This membrane is able to allow the nanosponges to travel safely, and in the blood stream. This will in return attract the toxins. Furthermore, Roco (2001) explains that researchers have come up with a method that has the capability of generating sound
