Abstract Salicornia europaea L. is a common halophytic plant species distributed in many saline soils and habitats, including margins of many wetlands. Salicornia europaea grows around Mighan Wetland, a natural desert ecosystem in central Iran with fluctuating water levels due to constant heat and severe wind throughout the year. Although, aspects of biology and ecology of halophytes growi...

Food safety is a crucial issue; all countries have struggled against pesticides for years. In this study, Polypyrrole (PPy)- and Polyacrylonitrile (PAN)-based non-enzymatic electrochemical sensors were investigated to detect the pesticide propamocarb (PM) in food samples. Under experimental conditions, proposed strategy exhibited high selectivity of disposable PPy-based PAN-based determination ...

Abstract The frequent detection of physiological glucose levels from human blood or sweat requires the development low‐cost electrodes with high sensitivity and selectivity. In this work, we prepared a series Prussian blue (PB) modified carbon cloth (CC) different cyanoferrate groups. We achieved as 145.43 μA m −1 cm −2 in 0.1–6.5 concentration range response time below 2 s under pH. exhibited ...

We review recent progress in the development of electrochemical biosensors based on ferroceneboronic acid (FcBA) and ferrocene (Fc)-modified boronic acids. These compounds can be used to construct electrochemical biosensors because they consist of a binding site (i.e., a boronic acid moiety) and an electrochemically active part (i.e., an Fc residue). By taking advantage of the unique properties...

Eccrine sweat has rapidly emerged as a non-invasive, ergonomic, and rich source of chemical analytes with numerous technological demonstrations now showing the ability for continuous electrochemical sensing. However, beyond active perspirers (athletes, workers, etc.), continuous sweat access in individuals at rest has hindered the advancement of both sweat sensing science and technology. Report...

increased nitric oxide (no) formation is mechanistically linked to pathophysiology of the extrahepatic complications of cirrhosis. no is formed by either enzymatic or non-enzymatic pathways. enzymatic production is catalyzed by no synthase (nos) while entero-salivary circulation of nitrate and nitrite is linked to non-enzymatic formation of no under acidic ph in the stomach. there is no data on...

We developed a carbon nanotube (CNT)-based biosensor system-on-a-chip (SoC) for the detection of a neurotransmitter. Here, 64 CNT-based sensors were integrated with silicon-based signal processing circuits in a single chip, which was made possible by combining several technological breakthroughs such as efficient signal processing, uniform CNT networks, and biocompatible functionalization of CN...

objectives: to evaluate the reliability of head and trunk acceleration measured by mtx sensors during walking on level and irregular surfaces and to compare the differences between healthy young and old adults. methods: participants were 20 young female university students and 20 non-faller elderly women in iran, 2013. two mtx sensors were used to measure head and trunk accelerations in the ver...
