PAYLOAD MOLECULE DELIVERY USING MOLECULAR REBAR

摘要

In various embodiments a payload molecule or drug molecule delivery system is disclosed. The system comprises a plurality of functionalized discrete carbon nanotubes having specific properties. The composition can comprise a plurality of discrete carbon nanotubes that have at least a portion of the carbon nanotubes with a number average (ratio of number average contour length to end to end length) of greater than 1.1 and up to about 3. These discrete carbon nanotubes having the specified ratio of number average (tube contour length (TCL) to number average tube end-end length (TEE)) ratio are not only discrete (separated) from one another, but are also controlled in their alignment such that processability and mechanical strength properties are both enhanced. Utility of the molecular rebar composition includes, but is not limited to improved payload molecule delivery, such as drug delivery, into body of an animal, such as human.
