Synthesis Of An Antimicrobial Textile Coating, William M. Morris Dec 2011

Synthesis Of An Antimicrobial Textile Coating, William M. Morris

Chemistry and Biochemistry

A titania nanosol was synthesized and coated onto nylon/cotton blended textile substrates. The substrates were characterized via SEM for adhesion and nanoparticle formation, then subjected to antimicrobial efficacy tests. The titania nanosol was successfully coated on to textiles samples. Particles were observed to be around 2 by 3 micrometers and formed between the interstitial space of textile fibers. Although larger than typical nanoparticles, the coatings exhibited what seemed to be antimicrobial activity. Titania nanosol coated textile samples were subjected to Kirby Bauer Assay in the presence of S. aureus. The coated textile sample exhibited an inhibition of growth around ...


Overexpression And Partial Purification Of Recombinant Human Serine Hydroxymethyltransferase: A Potential Anticancer Target, Suprit Singh Deol May 2010

Overexpression And Partial Purification Of Recombinant Human Serine Hydroxymethyltransferase: A Potential Anticancer Target, Suprit Singh Deol

Chemistry and Biochemistry

Serine Hydroxymethyltransferase (SHMT) is a member of the thymidylate synthase cycle that provides pyrimidine nucleotides to actively dividing cells, including cancer cells. The other two enzymes involved in this cycle have been targets for clinical anticancer drugs, suggesting that inhibitors of SHMT may also be used as clinical anticancer drugs. In order to test potential inhibitors against SHMT, human SHMT has been overexpressed in E. coli and partially purified by selective ammonium sulfate fractionation followed by anion-exchange fast protein liquid chromatography. A coupled assay using L-allo-threonine and alcohol dehydrogenase was used to identify active fractions, which were analyzed ...
