Vitamins such as folic acid and biotin are used as targeting agents in tumor targeted drug delivery system. The process of drug delivery takes place through Endocytosis. Vitamins are conjugated to cytotoxic agent with the help of a linker. This mechanism based vitamin receptor mediated drug delivery system is tumor specific and highly efficient. The sequence of events involved are validated and monitored with fluorescent probes using confocal fluorescence microscopy (CFM). This mechanism based tumor-targeting drug delivery system will find a wide range of applications. The problem of systemic cytotoxicity involved with conventional chemotherapy can be avoided using this drug delivery system. This literature review gives a basic outline of the process of vitamin receptor mediated Endocytosis as a tumor targeting drug delivery system.


The preservation and distribution of student research in the form of capstone project summaries, thesis work, and other student work is an important part of the University Library’s responsibility to conserve and disseminate knowledge created at the University.

This record is an indication that the University Library has received and is preserving the approved manuscript, but at the time of posting lacked permission for full-text publication.
