5.2 Drug Delivery System
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
Tidal stream generators (TSGs) make use of the kinetic energy of moving water to power turbines, in a similar way to wind turbines that use moving air.
A TSG is a machine that extracts energy from moving masses of water, or tides.
Energy can be captured from tidal streams using two methods,
Tidal fences and Tidal turbines.
Dynamic tidal power or DTP is a new an
