Improved stability and altered selectivity of tyrosinase based graphite electrodes for detection of phenolic compounds
TLDR
In this article, the authors investigated the operational and storage stability of different tyrosinase modified electrodes, i.e., plain bulk modified carbon paste electrodes (CPEs), surface modified by simple adsorption to solid graphite electrodes (SGEs), and surfaces modified by the immobilisation in Eastman AQ, a poly ester-sulphonic acid cation exchanger, and Nafion, a perfluorinated sulphonated ionomer, on the surface of both CP and SGEs.About:

Potential applications of oxidative enzymes and phenoloxidase-like compounds in wastewater and soil treatment: a review
Nelson Durán,Elisa Esposito +1 more
TL;DR: Immobilization of oxidative enzymes on porous ceramic supports or resins did not adversely affect their stability and showed a good potential for degradation of environment persistent aromatics.

Development of a tyrosinase biosensor based on gold nanoparticles-modified glassy carbon electrodes: Application to the measurement of a bioelectrochemical polyphenols index in wines
TL;DR: In this article, a tyrosinase biosensor based on the immobilization of the enzyme onto a glassy carbon electrode modified with electrodeposited gold nanoparticles (Tyr-nAu-GCE) is reported.
Journal ArticleDOI
Effects of fungal laccase immobilization procedures for the development of a biosensor for phenol compounds.
TL;DR: Fungal laccase was immobilized on carbon-fiber electrodes using classical methods: physical adsorption, glutaraldehyde, carbodiimide and carbodiIMide/glutaraldehyde to obtain a biosensor that showed an optimum response at pH 5.0 and at an applied potential of -100 mV.

An amperometric biosensor based on multiwalled carbon nanotube-poly(pyrrole)-horseradish peroxidase nanobiocomposite film for determination of phenol derivatives.
TL;DR: An amperometric biosensor based on horseradish peroxidase (HRP) and carbon nanotube (CNT)/polypyrrole (PPy) nanobiocomposite film on a gold surface has been developed and CNTs was shown to enhance the electron transfer as a mediator and capable to carry higher bioactivity owing to its intensified surface area.

Are oestrogens involved in falling sperm counts and disorders of the male reproductive tract
TL;DR: It is argued that the increasing incidence of reproductive abnormalities in the human male may be related to increased oestrogen exposure in utero, and mechanisms by which this exposure could occur are identified.

p-Nonyl-phenol: an estrogenic xenobiotic released from "modified" polystyrene.
TL;DR: The estrogenic properties of alkylphenols, specifically nonylphenol, indicate that the use of plasticware containing these chemicals in experimental and diagnostic tests may lead to spurious results, and these compounds as well as alkyLphenol polyethoxylates may also be potentially harmful to exposed humans and the environment at large.

Carbon paste electrodes modified with enzymes, tissues, and cells
TL;DR: A review dealing with the use of carbon paste amperometric electrodes for electroanalytical purposes, with either the surface or the bulk being modified with biologically derived material such as enzymes, tissues, and cells is presented in this paper.
