Laser-Treated Screen-Printed Carbon Electrodes for Electrochemiluminescence imaging.

Electrochemiluminescence (ECL) is nowadays a powerful technique widely used in biosensing and imaging, offering high sensitivity and specificity for detecting and mapping biomolecules. Screen-printed electrodes (SPEs) offer a versatile and cost-effective platform for ECL applications due to their ease of fabrication, disposability, and suitability for large-scale production. This research introduces a novel method for improving the ECL characteristics of screen-printed carbon electrodes (SPCEs) through the application of CO laser treatment following fabrication.

Measuring factors associated with telehealth use by people who use mental health services: A psychometric analysis of a theoretical domains framework questionnaire.

Introduction: Telehealth has the potential to improve access to mental health care, especially for people living in rural and remote regions. Yet, telehealth accessibility remains a challenge in Australia, and there is a scarcity of appropriate, psychometrically sound tools for evaluating telehealth use by mental health service users. The aim of this study was to adapt and validate a scale for measuring factors associated with mental healthcare telehealth use.

Willingness to participate in placebo-controlled surgical trials of the knee.

Aims: Surgeon and patient reluctance to participate are potential significant barriers to conducting placebo-controlled trials of orthopaedic surgery. Understanding the preferences of orthopaedic surgeons and patients regarding the design of randomized placebo-controlled trials (RCT-Ps) of knee procedures can help to identify what RCT-P features will lead to the greatest participation. This information could inform future trial designs and feasibility assessments.

Tunable electrochemiluminescence of TADF luminophores: manipulating efficiency and unveiling water-soluble emitters.

Thermally Activated Delayed Fluorescent (TADF) luminophores offer the potential to achieve 100% Internal Quantum Efficiency (IQE) by harvesting both singlet and triplet excitons reverse intersystem crossing from T to S. This class of molecules has therefore been embraced in the pursuit of cheaper and more efficient electrochemiluminescent (ECL) labels. The present study explores how tuning the electron-donating (D) and -accepting (A) strengths of peripheral substituents affects the ECL emission of mono- and dicyanoarene-based TADF dyes.

Dye self-organization in doped silica nanoparticles increases the electrochemiluminescence emission in magnetic bead-based assays.

We have investigated the effect of dye distribution on the electrochemiluminescence (ECL) intensity measured with a simplified magnetic bead-based immunoassay for two families of silica nanoparticles (NPs) doped with the cationic Ru(bpy) and the zwitterionic Ru(bpy)bps complexes (bps = bathophenanthroline disulfonate). The NPs doped with the Ru(bpy)bps complex, which can efficiently self-organize in the NP volume favoring ECL generation, resulted in 150-400% signal enhancement compared to the Ru(bpy)-doped ones.
