Developing Novel Nanoparticulated Imaging System Using Luminescence Enhancement Of Eu(Iii) And Tb(Iii) By Single-Strand Dna Encapsulation, David A. Corcoran, Diana L. Harms (Galindo)

All Student Theses

Non-toxic biosensors are encountering an increase in attention for use in understanding the fate of cells and as a diagnostic tool. Development and incorporation of suitable fluorophores into biological molecules is the key for monitoring proteins in vivo research. This study investigated the enhanced emission of Eu (III) and Tb (III) upon binding to the four DNA bases and their respective nucleotides, found the best ratio for effective energy transfer, and developing nanoparticles to deliver the biosensor into the cells.

It is well known that Eu (III) and Tb (III) exhibit very distinctive photo-characteristics. The luminescence of these two lanthanides …
