Diagnostic and therapeutic values of nanotechnology in cancer management

The early diagnosis and successful management of cancer have always been a challenge. The emerging field of nanotechnology is valuable both with respect to early diagnosis at the most incipient stages and highly targeted harmless treatment which makes this technology an undisputed unique landmark in the milestone of cancer management. This paper reflects a triangular trap approach for cancer therapeutics using nanotechnologybased nanomaterials such as dendrimers, quantum dots (QDs), and nanobubbles. The dendrimers serve as targeted anticancer therapy sparing the adjacent normal cells. The concept of encapsulation and conjugation helps in trapping the drug molecules and targeting them to the specific sites and ultimately releasing them. QDs are nanometersized semiconductor crystals which serve as early detection tools of cancer. They are composed of cadmium selenide. They possess the ability to glow when they are subjected to ultraviolet light. They play a significant role not only in the early diagnosis of cancer but also in target destruction of the cancerous cells. Nanobubbles are plasmonic (gold) nanoparticles. They cause the destruction of cancerous cells by means of tiny explosions.
