- Biomedical Engineering
Background:
- Carbon nanotubes (CNTs) are explored as versatile nanocarriers for drug delivery.
- Effective drug conjugation requires hydrophilic modifications of CNT surfaces.
- Existing methods involve chemical reactions or amphiphilic coatings.
Purpose of the Study:
- To present detailed approaches for covalently linking drug compounds to multiwalled carbon nanotubes (MWCNTs).
- To describe methods for labeling synthesized drug-MWCNT conjugates with fluorescent or radioactive molecules.
Main Methods:
- Hydrophilic modification of CNTs via addition reactions or carboxylic group functionalization.
- Covalent attachment of drug molecules to modified MWCNTs.
- Post-conjugation labeling with fluorescent dyes or radioactive isotopes.
Main Results:
- Successful covalent linkage of drug compounds to MWCNTs was achieved.
- Synthesized drug-MWCNT conjugates were effectively labeled for tracking.
