Paper-based vapor detection of hydrogen peroxide: colorimetric sensing with tunable interface.
Vapor detection of hydrogen peroxide still remains challenging for conventional sensing techniques, though such vapor detection implies important applications in various practical areas, including locating IEDs. We report herein a new colorimetric sensor system that can detect hydrogen peroxide vapor down to parts per billion level. The sensory materials are based on the cellulose microfibril n...
متن کاملA Dual colorimetric and Fluorometric Anion Sensor Based on Polymerizable 1, 8-Naphthalimide Dye
A new polymerizable fluorescent sensor based on the photoinduced electron transfer PET for the selective determination of fluoride ions in DMF solutions has been synthesized. The sensing system was prepared by incorporating 4-Amino-1,8-naphthalimide derivatives containing thiourea side chain at the amino moiety AFTN as a neutral F- selective flourophore and was characterized by use of the DSC, ...
متن کاملTapered Optical Fiber Coated with ZnO Nanorods for Detection of Ethanol Concentration in Water
This work presents ZnO nanorods coated multimode optical fiber sensing behavior in response to ethanol solution. The sensor operates based on modulation of light intensity which arises from manipulation of light interaction with the ambient environment in sensing region. For this purpose, two steps are experimentally applied here; etching and then coating fiber with ZnO nanorods to provide stro...
متن کاملThe Potentials and Applications of Cellulose Acetate in biosensor technology
The interest in cellulose and its derivatives has been exponentially increasing due to its excellent thermal stability, biocompatibility, chemical persistence and biodegradability. Among various cellulose derivatives, cellulose acetate (CA) has been applied in many applications including sensor systems, drug delivery systems, separation membrane, and tissue engineering. Recently, the electrospu...
متن کاملDissolution and Regeneration of the Produced Nano Bacterial Cellulose of Food Industries Wastewaters by a Cost-Benefit Method
This paper applied a simple and cost-benefit method for the production of regenerated bacterial cellulose. The inexpensive production of cellulose with complex media derived from wastewater from food industries such as molasses adds a lot of contaminants to the produced bacterial cellulose, which puts a lot of challenges in cellulose purification. Therefore, the present study aimed...
