Nitric oxide sensors using combination of p- and n-type semiconducting oxides and its application for detecting NO in human breath
نویسندگان
چکیده
Mixtures of WO3 and Cr2O3 in varying weight ratios as well as adjacent alignment of these two powders were both examined as possible designs for NO-selective sensor. Studies focused on resistance measurements toward NO and CO at 300 ◦C were carried out. Using the sensor design with the adjacent alignment of n-type WO3 and p-type Cr2O3 resulted in optimal performance. This sensor design exploits the differ-

Semiconducting properties of passive films formed on AISI 420 stainless steel in nitric acid solutions
This study focuses on the semiconductor properties of passive films formed on AISI 420 stainless steel immersed in four nitric acid solutions under open circuit potential (OCP) conditions. For this purpose, the passivation parameters and semiconductor properties of passive films were derived from potentiodynamic polarization and Mott–Schottky analysis, respectively. The OCP plots showed that th...
متن کاملP-96: Survey of In Vitro Effect of Noscapine on Nitric Oxide Secretion of Human Endometrial Stromal Cell
Background: Noscapine is cough suppressant drug with cell inhibitory effect. It is introduced for anti-cancer treatment. The aim of present study was to determine in vitro noscapine effect on nitric oxide (NO) secretion by human endometrial stromal cells. Materials and Methods: Human endometrial biopsies (n=8) were obtained in sterile condition and were chopped mechanically and digested by enzy...
متن کاملUnderstanding the Potential of WO3 Based Sensors for Breath Analysis
Tungsten trioxide is the second most commonly used semiconducting metal oxide in gas sensors. Semiconducting metal oxide (SMOX)-based sensors are small, robust, inexpensive and sensitive, making them highly attractive for handheld portable medical diagnostic detectors. WO₃ is reported to show high sensor responses to several biomarkers found in breath, e.g., acetone, ammonia, carbon monoxide, h...
متن کاملP-113: Survey of In Vitro Effect of Resveratrol on Nitric Oxide Secretion of Human Endometrial Epithelial Cells
Background: Resveratrol is a natural polyphe- nolic compound, synthesized by plants as a phytoalexin and protects against ultraviolet radiation and fungal infection. Nitric oxide is formed from L-arginine through nitric oxide synthases (NOS), a group of enzymes that structurally resemble cytochrome P-450 reductase. In females, circulating NO is increased during follicle development and decrease...
متن کاملEffects of a Nitric Oxide releasing cream on cutaneous Leishmaniasis in animal model
Background an objective: Leishmaniasis is a common disease endemic in some parts of Iran. Chemical or physical treatments or a combination of both are used for treatment of the disease. Nitric oxide (NO) is important for healing of leishmaniasis in human and animal. This study was designed to evaluate the beneficial effects of a NO releasing cream on cutaneous leishmaniasis in an animal m...
