We intend to introduce a high-level article on drug delivery with carbon nanotubes and how to use nanoscale nanotubes in drug delivery. To achieve this goal, we first introduce the drug Nimesulide, and it is said that if it does not reach the target tissue and elsewhere, it is highly toxic and dangerous and has irreparable effects, as prohibited by many countries. , But using closed carboxyl nanotubes, it is possible to place the Nimesulide drug into these nanotubes, and when we reach the target tissue, we use external light radiation to release the nanotubes and release the drug precisely into the tissue the goal is to have no other toxic effects for other tissues in the body.
