The advantages of using nanoparticles as a drug delivery system include: 1  The size and surface characteristics of nanoparticles can be easily manipulated. 2  Nanoparticles can be made to control and sustain release of the drug during the transportation as well as the location of the release.
The average cost to replace a cesspool with a conventional septic system is approximately $10,000-$15,000. However, replacements on very small lots, lots in close proximity to wells and water bodies, or lots subject to other constraints might not be feasible with conventional septic systems.
