Formation, Characterization, And Optimization Of Antibody-Gold Nanoparticle Conjugates, Seth L. Filbrun

Theses and Dissertations

Protein modified gold nanoparticle based immunoassays are the basis of many novel detection techniques. There are many groups working on novel immunoassays but there is still much to understand about how many proteins are attached onto each nanoparticle and much to improve on immobilization methods. This thesis work is devoted to improving techniques for the quantification of protein immobilized on the gold nanoparticle and development of a novel approach to immobilize protein independent of pH.

The ability to evaluate antibody immobilization onto gold nanoparticles is critical for assessing coupling chemistry and optimizing the sensitivity of nanoparticle-enabled biosensors. Herein, we developed …
