“…Moreover, some of them are not suitable for the detection of APAP at very low concentrations. This has generated the development of electrochemical methods recognized to be inexpensive, sensitive, and selective [24][25][26][27]. The resort to electrochemical methods for the determination of biological compounds in environmental analysis is also because they are reagentless and require simple operational procedures [28].…”

The nonpathogenic filamentous fungus Scedosporium dehoogii was used for the first time to study the electrochemical biodegradation of acetaminophen (APAP). A carbon fiber microelectrode (CFME) modified by nickel tetrasulfonated phthalocyanine (p-NiTSPc) and a carbon paste electrode (CPE) modified with coffee husks (CH) were prepared to follow the kinetics of APAP biodegradation. The electrochemical response of APAP at both electrodes was studied by cyclic voltammetry and square wave voltammetry. p-NiTSPc-CFME was suitable to measure high concentrations of APAP, whereas CH-CPE gave rise to high current densities but was subject to the passivation phenomenon. p-NiTSPc-CFME was then successfully applied as a sensor to describe the kinetics of APAP biodegradation: this was found to be of first order with a kinetics constant of 0.11 day(-1) (at 25 °C) and a half-life of 6.30 days. APAP biodegradation by the fungus did not lead to the formation of p-aminophenol (PAP) and hydroquinone (HQ) that are carcinogenic, mutagenic, and reprotoxic (CMR). Graphical Abstract The kinetics of APAP biodegradation, followed by a poly-nickel tetrasulfonated phtalocyanine modified carbon fiber microelectrode.

“…It is also critical in mental disease, heart-failure, DNA breaks in cardiac myoblast cells, and diabetes. Recent reports have indicated that NE enhances adhesion of human immunodeficiency virus-1 (HIV-1)-infected leukocytes to cardiac microvascular endothelial cells and also accelerates HIV replication via proteinkinase [7][8][9]. On the other hand, NE acts as the stimulant which is included in the World Anti-Doping Agency's 2005 Prohibited List [10,11].…”

Surface plasmon resonance sensor for norepinephrine using a monolayer of a calix[4]arene crown ether

et al. 2015

The article describes a calix[4]arene derivative for use as a recognition element in an SPR sensor for norepinephrine (NE). The calix[4]arene carries a crown ether and a thiol group that enables the formation a self-assembled monolayer (SAM) on a gold surface. NE is recognized by the calix[4]arene via its positively charged amino group that has a high affinity for the crown moiety of the calixarene. The modified gold surface was characterized by Fourier transform infrared reflection absorption spectroscopy, atomic force microscopy, and cyclic voltammetry. The binding process to the sensor surface was monitored by SPR. Under optimized condition, the sensor has a linear response to NE in the 10 pM to 100 nM concentration range, and the detection limit is 0.12 pM.
