Wireless Sensor Networks (WSN) has attracted a lot of attention due to its huge application space. In a WSN, the routers are stationary and they are able to communicate with each other via the wireless mesh link, the sensors can move from place to place in the region of the network and deliver their data to the gateway through the routers, a gateway(More)
BACKGROUND TGFBR1*6A is a common hypomorphic variant of transforming growth factor beta receptor 1 (TGFBR1). TGFBR1*6A is associated with an increased cancer risk, but the association of this polymorphism with osteosarcoma remains unknown. We have measured the frequency of TGFBR1*6A variants in osteosarcoma cases and controls. METHODS Our case-control(More)
A polymer-coated surface acoustic wave (SAW)-based chemical sensor for organophosphorous compound sensing at extremely low concentrations was developed, in which a dual-delay-line oscillator coated with fluoroalcoholpolysiloxane (SXFA) acted as the sensor element. Response mechanism analysis was performed on the SXFA-coated chemical sensor, resulting in the(More)
This paper presents a new effective approach for the sensitive film deposition of surface acoustic wave (SAW) chemical sensors for detecting organophosphorus compounds such as O-ethyl-S-2-diisopropylaminoethyl methylphosphonothiolate (VX) containing sulfur at extremely low concentrations. To improve the adsorptive efficiency, a two-step technology is(More)
Rapid and sensitive detection methods are in urgent demand for the screening of extensively used organophosphorus pesticides and highly toxic nerve agents for their neurotoxicity. In this study, we developed a novel Fe(3)O(4) magnetic nanoparticle (MNP) peroxidase mimetic-based colorimetric method for the rapid detection of organophosphorus pesticides and(More)
In this paper, a polyaniline (PANI)-coated Surface Acoustic Wave (SAW) sensor was developed for humidity detection. Based on the coupling-of-modes (COM) simulation, 150 MHz two-port SAW resonators with low insertion loss and high Q factor were designed and fabricated on the ST-X quartz substrate with Al strips. Dual-resonator oscillator was built for gas(More)
Removal of carbon dioxide is an essential step in many energy-related processes. Here we report a novel slurry concept that combines specific advantages of metal-organic frameworks, ion liquids, amines and membranes by suspending zeolitic imidazolate framework-8 in glycol-2-methylimidazole solution. We show that this approach may give a more efficient(More)
Self-assembly and molecular imprinting technologies are very attractive technologies for the development of artificial recognition systems and provide chemical recognition based on need and not happenstance. In this paper, we employed a b-cyclodextrin derivative surface acoustic wave (SAW) chemical sensor for detecting the chemical warfare agents (CWAs)(More)
