Nanomedicine is defined as the medical application of nanotechnology. Nanomedicine can include a wide range of applications, including biosensors, tissue engineering, diagnostic devices, and many others. In the Center for Nanomedicine at Johns Hopkins, we focus on harnessing nanotechnology to more effectively diagnose, treat, and prevent various diseases. Our entire bodies are exposed to the medicines that we take, which can lead to unpleasant side effects and minimize the amount of medicine that reaches the places where it is needed. Medications can be more efficiently delivered to the site of action using nanotechnology, resulting in improved outcomes with less medication.
Nanomedicine is the application of the principles and methods of nanoscience and technology to medicine. Its scope mainly includes two aspects: (1) The application of nanoscience and technology to develop more sensitive and rapid medical diagnostic techniques and more effective treatment methods; (2) Use nanotechnology to understand the process and mechanism of life activities on a more micro level.
The value of nano-medicine
Judging the value of nanomedicine can be considered from the following aspects : (1) whether it can improve the curative effect of incurable diseases, (2) whether it can solve some "orphan diseases" treatment methods, (3) whether major diseases can be obtained Better treatment, (4) whether it has an impact on medicine, (5) whether it can bring benefits to medical care in developing countries, (6) whether nanomedicine meets medical ethics and has sustainable development capabilities, (7) nanometer How will medicine affect our society, culture and worldview.
