Abstract: Cancer is a major killer of human, effective diagnosis and treatments are important. Nanotechnology has better bioavailability, such as high stability, high target characteristic and excellent optical performance. Diagnosis and targeted therapy based on nanotechnology can effectively enhance drug utilization and anti-tumor activity, reduce the normal tissue toxicity and solve the problem of drug resistance, and thus contribute significantly to the development and progress of chemotherapy. Nanotechnology for the early diagnosis and treatment of tumor has brought new opportunities. The present article reviewed the various kinds and characteristics of nanoparticles and the application in cancer in label and trace, diagnosis and treatment.
