Abstract
Phytochemicals having multiple properties which are used to cure various diseases such as cancer, diabetes, neurodegeneration, angiogenesis, aging, inflammatory, cardiovascular and arthritic disease, etc., Extensive use of phytochemicals and their derivatives leads to unavailability or scarcity of products in nature. Despite this episode, the nanotechnology resolves the setback of handling phytochemicals by increasing their bioavailability, longlost acting, target-specific and less or no toxicity. Here, we focused on the 24 known phytochemicals and preparation of NPs without discriminating the polymers and metals in NPs. All the phytochemicals did not fully satisfy the toxicological hazards, physical-pharmaceutical challenges, bioethical and health issues research. Hence these NPs and their NP incorporated phytochemicals need to be characterized in a way to give direct usage to the common man. Commercialization of NP formulations in pharmaceuticals needs statutory regulation norms for complete satisfaction and safety for endusers. As of now, many NP mediated pharmaceutical products are available in the market with full-fledged but still many unrevea led about their fate in the environment. In this review, the characterization of nanoparticles, the transparent benefit of nanoparticles (NPs), and their current application in various fields has been discussed.
