New nano-devices for cancer diagnosis and therapeutic treatment

Cancerous cells and tumours may occur in any part of the body any time and hence proper diagnosis and treatment of such diseases would need immediate attention. Presently, conventional radiological diagnostic and therapeutic techniques are in use but more reliable and quick techniques are required to be developed to tackle the problem of cancer and tumours, in an effective manner. The current diagnosis techniques are usually in tissue level, and have limitation of low efficiency to detect specially invisible cancer cells. The treatment technique for cancer has been surgery, with or without radiotherapy, for years, while chemotherapy, is also used extensively these days, but this has its limitation of efficacy and the patients suffer from severe side effects.
