Nanomedicine is a new nanotechnology that has a huge impact on the human lives. With many studies and researchers, the human has used to the nanomedicine to operate many various medical functions such as drug delivery, cancer therapeutics, tissue engineering, etc. Nanomedicine has brought many benefits for human, especially assist the physicians in order to promote the healthcare, treatments, and patient’s health. However, like other technology, it opposes many legal and ethical issues and the security aspects that people question. There are risks and unpredicted consequences that the scientists have not been observed, therefore, it irritates other people. According to the researchers, the nanomedicine generates more benefits than harm for the human. Unlike the robotic surgery, the nanomedicine is more commonly used due to its convenience in size to perform many difficult tasks that human cannot operate. Nanomedicine is a new improvement in technology and it can create unknown risks and problems, however, no one has opposed to its application on the human yet. Researchers have been conducted to continually discover the nanomedicine, so it can be improved and performs its function better to help the physicians in the healthcare.
