Electrical detection of trace zinc ions with an extended gate-AlGaN/GaN high electron mobility sensor

Abstract

In this report, we have developed a high sensitivity zinc ion (Zn2+) detection method based on a Schiff base functionalized extended gate (EG)-AlGaN/GaN high electron mobility (HEMT) sensor.

“…On the other hand, excessive Zn causes movement disorder, coma, and copper deficiency. [1][2][3][4] Zn presents in many media such as blood, water, and food. When it is absorbed into our body, it is not discharged completely and accumulates to cause various diseases or side effects.…”

“…At present, a variety of Zn 2+ detection and analysis methods have been developed, including electron mobility sensor, gravimetric method, colorimetric method, polarographic method and ame atomic absorption spectrophotometry [18][19][20][21][22]. However, these methods have some unavoidable disadvantages that hinder their application for rapid detection, such as the troublesome procedures, serious interference from other elements, the participation of inert gas, professional operation technology and being di cult to realize real time detection.…”

Highly selective and sensitive electrochemical sensing of trace Zn2+ ions, by grafted Tricholoma mushroom polysaccharide/Ag composite nanoparticles in aqueous medium

“…[ 1–5 ] Interaction of other cellular component with Zn 2+ ions leads to several type of diseases like Alzheimer's disease, type‐I diabetics, cancer, Parkinson's disease, ischemic stroke and so on. [ 6–10 ] According to the World Health Organization (WHO), the presence of Zn 2+ in drinking and human serum would be 76 and 10 μM, respectively. [ 8 ] But in the presence of excess amount of Zn 2+ in human body leads to cytotoxicity.…”

[ 11 ] Several human activities may cause to release of heavy metal ions in terrestrial system and aquatic life such as mining, agriculture and industrial process which further transfer to humans, animals, plants and living systems.…”
