A nanosecond pulsed laser-ablated MWCNT-Au heterostructure: an innovative ultra-sensitive electrochemical sensing prototype for the identification of glutathione

Abstract

Here developed a scheme that aptly describes the reduction of gold nanoparticles' crystalline size on the surface of MWCNT in an aqueous phase to generate LAMWCNT-Au heterostructure, employing a Nd:...

An iron metal–organic framework-based electrochemical sensor for identification of Bisphenol-A in groundwater samples

“…Lastly, the resulting mixture was put into a Teflon bottle and irradiated for about 30 minutes with 5 minutes irradiation on and 1-minute irradiation off in a 700 Watts microwave oven. 14 After centrifuging for 15 minutes at 8000 rpm, the product was rinsed three times with distilled water followed by one time rinse with ethanol. The solid acquired a brown colouring shortly after spending the night in an 80 °C furnace.…”

“…Metal-organic frameworks (MOFs) have the potential to serve as optical sensors, electrochemical sensors, and biosensors. [14][15][16] Several studies were conducted to identify and detect environmental pollutants. 17 Several scholarly evaluations and reports have also been dedicated to utilizing Metal-Organic Frameworks (MOFs) in gas sensing.…”

“…17 Several scholarly evaluations and reports have also been dedicated to utilizing Metal-Organic Frameworks (MOFs) in gas sensing. 14,15,[18][19][20][21][22] Nevertheless, the research conducted on Metal-Organic Frameworks (MOFs) as sensing materials is still in its nascent phase, and there needs to be more comprehensive advancements in the exploration of MOF applications in the field of sensors. The insulating property of MOF limits its application in electrochemical sensors when contrasting MOF-based optical and electrochemical sensors.…”

“…23 However, some recent research has shown that MOF candidates have enough electroconductivity. 14,[24][25][26][27] The studies of impedance were applied to determine the MOF's (Fe-BTC) potential to sense air humidity. 28 Fe-BTC MOFs have become a notable Fe-based MOF substance during current investigations.…”

A copper metal–organic framework-based electrochemical sensor for identification of glutathione in pharmaceutical samples

“…In the context of cellular and tissue health, it is observed that over 90% of the entire glutathione reservoir is present in its reduced state, known as GSH, while less than 10% is found in the disulfide form, referred to as GSSH. 7 GSH is a crucial cofactor in numerous biological processes, including but not limited to catabolism, drug movement and detoxification. It also plays a vital role in facilitating intercellular communication through gap junctions and acts as a protective agent against the oxidation and cross-linking of protein-SH groups.…”
