5.2.1 Advantage of Nano-drug delivery system
By diagnosis, and for treatment, we need enhanced drug delivery system. Drug delivery system of these days is just eat and let it flow through the body. It is not good at efficiency. Because the digestive system sometimes digest and remove the drug before it reaches to the target.
For enhancing the efficiency of drug
According to the Global Environment Fund, the Gulf and Sea of Oman region is "one of the most important marine turtle habitats in the world and plays a significant role in sustaining the life cycle of the marine turtle populations in the whole North-Western Indo Pacific region" due to its shallow depth and high water temperature.

- How to send the lenses into orbit, in one piece. Since conventional rocket systems with fossil fuel are expensive and polluting, professor Angel hopes to use a coil gun. While it could take 30 years to perfect, this technology might possibly be a revolutionary breakthrough in space travel. Angel's plan is for 20 coil guns to be built around the world, buried deep in mountains. The vertical gun
