Glucose Biosensor Using Electrospun Mn2o3-Ag Nanofibers, Shan Huang Aug 2011

Glucose Biosensor Using Electrospun Mn2o3-Ag Nanofibers, Shan Huang

Master's Theses

The highly porous Mn2O3-Ag nanofibers were fabricated by a facile two-step procedure (electrospinning and calcination) and then employed as the immobilization matrix for glucose oxidase (GOD) to construct an amperometric glucose biosensor. A notable enhancement of direct electron transfer between GOD and the electrode is observed at the Mn2O3-Ag-GOD modified electrode with a fast electron transfer rate constant. The biosensor also shows fast response to glucose, high sensitivity (40.60 μA×mM-1×cm-2), low detection limit (1.73 µM at S/N=3), low Km,app value and excellent selectivity. These results indicate that …

A Comparative Study Of Total Hemoglobin Measurement Technology: Noninvasive Pulse Co-Oximetry And Conventional Methods, Jared S. Ruckman May 2011

A Comparative Study Of Total Hemoglobin Measurement Technology: Noninvasive Pulse Co-Oximetry And Conventional Methods, Jared S. Ruckman

Master's Theses

Hemoglobin can be measured on a variety of devices using different principles of operation. Noninvasive pulse CO-oximetry represents the latest development in hemoglobin measuring technology. The technology uses principles similar to pulse oximetry to measure total hemoglobin, oxyhemoglobin, reduced oxyhemoglobin, carboxyhemoglobin and methemoglobin. Similar to the introduction of pulse oximetry to the medical field, pulse CO-oximetry has been met with skepticism. Since the technology is noninvasive and provides continuous monitoring in comparison to invasive and discrete techniques used in other methods, CO-oximetry purportedly provides an advantage in patient care. The purpose of this research is threefold: (a) to review the …
