The emergence of nanotechnology is likely to have a significant impact on drug delivery sector, affecting just about every route of administration from oral to injectable. The illustration at left is created for USC's alumni magazine to describe researchers work on nanotechnology drug delivery systems.
The illustration depicts a theoretical, stable, helical nanotube structure, which is analogous to that seen in crystal growth affected by screw dislocations. The structure is composed of 5, 6 and 7 membered-rings. Carbon rings with 5 members are shown in red, 6 in grey and seven in yellow. There is a passing resemblance to the spiral structure of DNA (but a single helix, obviously). Also referred to as "helicoidal graphite".
Nanotube powder is incredibly light and fluffy! This sample is a pile about half an inch wide the way it's stacked in the photo, but it weighs only about 7mg (0.007 grams). A full liter of this stuff would weight only about 25 grams, 40 times less dense than water.
Antibodies are proteins that are generated by the immune system, specifically the white blood cells. They circulate in the blood and attach to foreign proteins called antigens in order to destroy or neutralize them.Monoclonal antibodies are laboratory produced substances that can locate and bind to specific molecules.
Nanoporous materials consist of a regular organic or inorganic framework supporting a regular, porous structure. Pores are by definition roughly in the nanometer range. This is an artistic representation of water molecules in nanoporous material.
