Determination of Hormone 17β‐Estradiol Using Graphite‐Acrylonitrile Butadiene Styrene Electrode Coupled to User‐Friendly 3D‐Printed Batch Injection Analysis Cell

Electroanalysis, Volume 37, Issue 10, October 2025.
β‐Estradiol (E2) is a hormone found in pharmaceutical samples and an emergent environmental contaminant. Here is proposed a rapid, simple, and low‐cost electroanalytical method for the determination of E2 in pharmaceutical and water samples using a coated graphite‐acrylonitrile butadiene styrene working electrode coupled to a novel user‐friendly 3D ...

A paper‐based bi‐enzymatic sensor for chemiresistive glucose detection

VIEW, Volume 6, Issue 5, October 2025.
This paper presents the development of a paper‐based glucose sensor utilizing poly(3,4‐ethylene‐dioxythiophene) polystyrene sulfonate (PEDOT:PSS) and a bi‐enzymatic system with Horseradish Peroxidase (HRP) and Glucose Oxidase (GOx). The chemiresistive sensor is optimized for detecting glucose in biofluids such as saliva, requiring only 40 µL of sample ...

Micropollutants and Their Interactions With Relevant Environmental Viruses

Environmental Microbiology, Volume 27, Issue 10, October 2025.
Environmental micropollutants increase virus stability. ABSTRACT Emerging pollutants encompass a diverse array of chemicals classified as micropollutants, including pharmaceuticals and microplastics (MPs). Viruses are known to adsorb onto MPs, including binding to bacterial biofilms that form the plastisphere.

An enzyme-immunoassay for estriol.

Endocrinologia Japonica, 1979
A practical method was developed for enzyme-immunoassay of serum estriol, with alkaline-phosphatase as a marker enzyme. Alkaline-phosphatase was conjugated with estriol-6-(O-carboxymethyl) oxime using water soluble carbodiimide. The estriol-alkaline-phosphatase complex, which has both enzyme activity and capacity to bind anti-estriol serum, was ...

Comprehensive genetic analysis of poorly differentiated gastric cancer in young females

Annals of Gastroenterological Surgery, Volume 9, Issue 5, Page 926-932, September 2025.
Although the involvement of female sex hormones in the development of poorly differentiated gastric cancer in young females is controversial, our detailed analysis using RNA‐seq suggested that the female sex hormone, β‐estradiol plays a role in the development of poorly differentiated gastric cancer in young females. Abstract Aim The reasons behind the
