Fabrication Of Protein Arrays Using Electron Beam Lithography, Duy-Bao Phan Dinh

Theses, Dissertations and Capstones

Very few electron beam based methods for producing high-resolution patterns of surface bound proteins on glass have been developed.

There are only two types of end groups at the surface of glass, they are silanol and siloxane groups. An estersil layer can be formed on the surface of glass by treatment with hot alcohol creating a hydrophobic layer. The reaction is depicted as follows.

-Si-OH + HOR -SiO-R +H2O R = alkyl chain

The proposal that protein arrays could be fabricated by patterned electron bombardment using estersils as a negative resist was tested in this research. The hydrophobic estersil layer …

Preparation Of N-(Haloaryl) Succinimides, Okey Noe Ii

Theses, Dissertations and Capstones

N-(3,5-Dichloro-4-fluorophenyl)succinimide (NDCFPS) and N-(3,5-dichloro-4- pyridyl)succinimide (NDPyS) were synthesized using procedures employed previously for N-(3,5-dichIorophenyl)succinimide (NDPS). However, NDPyS was not formed cleanly: extraction from by-products was necessary and purification by column chromatograpy was required. Several potential alternative routes to NDPyS were investigated without success.

Both compounds were administered to male Fischer 344 rats to assess nephrotoxic potential. NDCFPS, contrary to expectations, was non-nephrotoxic. Preliminary results indicate that NDPyS is also non-nephrotoxic.
