Recent Paradigms in Nanomaterial‐Assisted Electrochemical (Bio) Sensing for Food Quality and Safety Analysis: A Critical Review

open access: yesFood Safety and Health, EarlyView.
ABSTRACT Rising global demand for safe and unadulterated foods has accelerated the need for rapid, low‐cost, and portable analytical technologies. Traditional laboratory methods, although accurate, are often labor‐intensive and unsuitable for decentralized, real‐time monitoring. In response, nanomaterial‐assisted electrochemical sensors have emerged as

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

High‐Content Screening Comparison of 1R6F Cigarette Smoke Extract and Selected Heated Tobacco and Electronic Vapour Product Aerosol Extracts in Endothelial and Bronchial Epithelial Cell Models

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Cigarettes induce oxidative stress and DNA damage, processes that contribute to cardiovascular and pulmonary disease. High content screening (HCS) is an increasingly valuable tool for comparative toxicology because it enables simultaneous quantification of multiple mechanistic endpoints at single‐cell resolution. In this study, HCS was used to

Development and Analytical Validation of a Smartphone‐Based Quantitative Lateral Flow Immunoassay for Serum Cystatin‐C

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
We developed a gold nanoparticle‐based lateral flow immunoassay that pairs a fixed‐geometry smartphone reader with an Android application for quantitative serum Cystatin‐C measurement. The 15‐min assay covered 0.32–8.00 mg/L with a 0.15 mg/L detection limit and CVs below 10%.

Establishment and Application of a Quantitative Lipemia Index as a Novel Indicator for Assessing Lipemic Interference in Clinical Chemistry

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
A rigorously validated quantitative lipemia index (LI) assay was established for direct serum turbidity measurement. This standardized LI metric demonstrated significantly stronger correlation with lipemic interference (rs = 0.822) than conventional triglyceride concentration (rs = 0.770), consistent with its direct measurement of optical turbidity ...

Bioelectrochemical single reactor for reductive and oxidative removal of trichloroethylene from contaminated groundwater

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Chlorinated aliphatic hydrocarbons such as trichloroethylene (TCE) are persistent groundwater contaminants due to improper disposal and low biodegradability. This work presents an innovative bioelectrochemical system for the integrated reductive/oxidative removal of TCE from contaminated water, implemented in a single tubular ...
