Synthesis of metal oxide nanomaterials for early lung disease detection
College of Science
Journal of Physics: Conference Series
Metal oxide nanomaterials from bulk zinc oxide and tin oxide powders were synthesized via Horizontal Vapor Phase Crystal Growth deposition technique. Synthesized nanomaterials were deposited in a silica quartz tube where it acts as sensing element of the gas sensor. Volatile organic compounds (VOCs) were utilized as identifier for lung disease which served as analytes to interact with the gas sensor. The sensitivity test was measured using its response time and voltage difference. An immediate voltage response time with an average of 3 seconds was observed upon exposure of the analyte to the sensor. Selectivity test was analyzed through radar plots of tin oxide and zinc oxide which depicted that each metal oxides have distinct sensing capabilities in terms of sensed VOC gases. © 2020 IOP Publishing Ltd.
