A stimulus-responsive poly-pyrrole nano tube targeted drug carrier and its preparation method
-
Paragraph 0082-0084, (2020/02/07)
The invention provides a stimulus-response type polypyrrole nanotube targeting drug carrier and a preparation method. A titanium dioxide nanotube array or a porous anodic alumina array serves as a template, and a polypyrrole nanotube is prepared through chemical vapor deposition; beta-cyclodextrin and a tube opening of a polypyrrole nanotube are connected through stimulus response type sensitive bonds such as acyl hydrazone bonds and disulfide bonds, and medicine can be blocked in the nanotube and released out in the faintly acid and reducibility environments; one end of a polyethylene glycol chain is connected with a folic acid targeted molecule, the other end of the polyethylene glycol chain is connected with an adamantane head base, the adamantane head base is linked up to a beta-cyclodextrin hydrophobic cavity through host and guest envelope, and folic acid molecules recognize tumor cells through a receptor-ligand medium. The stimulus-response type polypyrrole nanotube targeting drug carrier prepared through the method is uniform in particle diameter size distribution, controllable in appearance, stable in product, simple in synthesis process, low in cost and suitable for mass production.
