Recent patents on plant derived nanoparticles and their potential application towards various cancer therapeutics.

BACKGROUND
Nanotechnology plays a vital role in the field of medicine. Especially various nanoparticles such as silver, gold, platinum were involved in the treatment of different type of cancer. The effective nanoparticles were synthesized using techniques like chemical, physical, electrochemical and biological methods. In order to overcome the limitations existing in the synthesis of nanoparticles, researchers turned their attention towards the biological single step nanoparticle synthesis method by using plant and plant products.


OBJECTIVE
To overcome the side effects encountered in the existing anti cancer agents like non specificity and fast excretion, plant derived nanoparticles that are ecofriendly, cost effective and biologically active could serve as a promising alternative.


CONCLUSION
From the thorough literature review and recent patents, it is understood that the plant derived nanoparticles exhibited an excellent anti proliferation, anti tumor activity towards different types of cancers without affecting the normal cells. Especially, the traditional chemotherapeutic drugs obtained from the plant source incorporated with the nanoparticles shows remarkable results against anti cancer studies. The present review focused on some of the existing herbal plant derived nanoparticles, formulations and its potential application towards cancer therapeutics.
