Slide 1: 

Nanomedicine: New Hope for Life

Medicine : 

Medicine The Science or practice of diagnosis, treatment and prevention of disease. Limitations: Non specificity Side effects

Slide 3: 

Nanomedicine Nanomedicine can be defined as the monitoring, repairing, construction and control of human biological systems at the cellular level by using materials and structures engineered at the atomic or molecular level

Slide 5:
