Based on studies showing that polymer chemistry in bioconjugates has a significant effect on self-assembly, an attempt to quantify these protein-polymer interactions was made using contrast-variation small-angle neutron scattering on mCherry and polymer blends.

This technique allows for decomposition of the scattering intensity into its component parts corresponding to correlations between the 3 different pairs of the 2 species in the blends. From this analysis, it was determined that the best ordering bioconjugates have primarily repulsive interactions that can be described using a depletion layer model.

Lastly, the effect of protein properties was screened using a large library of bioconjugates made from 11 different proteins. The primary observed trend was that order increases as molecular weight increases, but a narrow region around kDa was observed where bioconjugate ordering was significantly enhanced and additional nanostructures were accessible. Recent years have seen an enormous increase in the use of protein reagents in the biological and medical sciences.

Enzyme conjugates and immobilised proteins are fundamental to many diagnostic applications, and existing therapeutic advances are being made using a range of approaches based on antibody conjugates.

Protein conjugation techniques are central to the development of these reagents. This book presents a unique introduction into the field of bioinorganic chemistry through practical laboratory experiments.

Topics include many aspects of modern bioinorganic chemistry such as model systems for metalloenzymes, biosensors, metal bioconjugates and metal-based drugs.

Each chapter contains a brief introduction, followed by detailed experimental procedures, completed with all necessary background information for the student as well as their instructors. A valuable supplement to standard textbooks of inorganic and bioinorganic chemistry Essential for all instructors teaching laboratory courses in general and inorganic chemistry.

Unnatural amino acid technologies have been critical in introducing unique chemical functionality to proteins to allow for specific protein modulation or preparation of well-defined, homogeneous bioconjugates through bioconjugation chemistry. Bioconjugates are tremendously useful in disease treatment, diagnosis, and imaging. Therefore, the development and optimization of novel unnatural amino acids and bioconjugation methods, and their application to protein modulation or bioconjugate formation is a critical field of biochemical investigation.

Then, several methods of preparing multivalent conjugates, which have a broader range of therapeutic applications than typical bivalent conjugates, are discussed. Finally, efforts to assay and modulate human protein arginine methyltransferase 1 using photoregulation unnatural amino acid technology are described. This thesis aims to expand the bioconjugation chemical toolbox, with high impact medicinal, therapeutic, and material applications.
