Claims23
A method for delivering an agent to a patient in situ, comprising:
- (a) providing a plurality of carbon nanotubes;
- (b) depositing the agent to the plurality of carbon nanotubes such that the agent is non-covalently associated with the plurality of carbon nanotubes;
- (c) placing the plurality of carbon nanotubes deposited with the agent at a target location in the patient's body;
- and
- (d) allowing the agent to diffuse from the plurality of carbon nanotubes, thereby delivering the agent in situ.

An implantable drug delivery device, comprising:
- (a) an implantable device;
- (b) an array of carbon nanotubes anchored on the implantable device;
- and
- (c) an agent deposited on the array of carbon nanotubes,
- wherein the agent is not covalently bound to the carbon nanotubes.

26-42. (canceled)
A method for monitoring in situ delivery of an agent, comprising:
- (a) providing a plurality of carbon nanotubes non-covalently associated thereon a pharmaceutical agent and a second agent capable of exhibiting a spatially detectable signal;
- (b) placing the plurality of carbon nanotubes at a target location in the patient's body;
- and
- (c) measuring the detectable signal exhibited from the second agent to monitor the deliver of the pharmaceutical agent in situ.
