Production, purification and characterization of chitosanase from Penicillium spinulosum
Ak, O; Bakir, U; Güray, Nülüfer Tülün (1998-11-01)
A chitosan degrading fungus which had been isolated in our laboratory and identified as Penicillium spinulosum by the International Mycological Institute (England), was used for the production of chitosanase in a salt medium containing Rhizopus cell walls as the sole carbon source. Although chitosanase was produced under all the conditions tested about 1 % cell wall concentration maximized enzyme production. The enzyme was purified 50 fold by using ammonium sulfate precipitation and ion-exchange chromatogra...

Preparation of gold decorated cobalt-silica core-shell nanoparticles for surface enhanced raman scattering applications
Keser, Lütfiye Sezen; Volkan, Mürvet; Department of Chemistry (2010)
Bringing together several materials into a single nanoparticle is an attractive way to design systems that exhibit diverse physical and chemical properties. Cobalt nanoparticles are extensively used in magnetic separation, ferrofluids, and magnetic storage media. The deposition of gold nanoparticles onto cobalt core significantly affects their optical properties due to the introduction of surface Plasmon. Here the synthesis of gold nanoparticles decorated cobalt-silica nanoparticles are reported for the fir...

Preparation and characterization of surface enhanced raman scattering substrate through electro deposition of silver-pedot film on ito glass surface
Doğan, Üzeyir; Volkan, Mürvet; Department of Chemistry (2011)
Detection of chemicals is a vital part of chemistry. For this reason, many detection systems are developed by scientists and every detection system has its own advantages. Raman spectroscopy is one of these detection systems having many advantages. However, this technique suffers from low signal intensity disadvantage. By developing a well prepared substrate, this problem can be easily solved; moreover, even single molecule detection can be possible. In this study, a novel surface enhanced Raman scattering ...
