This study introduces the development of a highly sensitive label-free electrochemical immunosensor specifically designed to detect prostate-specific antigen (PSA). A glassy carbon electrode (GCE) coated with Au nanoparticles/polyhedral hollow CoCu bimetallic sulfide (CuCoS) was employed as a sensing interface for the fixation of the monoclonal anti-PSA antibody. The nanoarchitectures enhanced the capacity for loading prostate-specific antibodies (Ab) and effectually boosted electrical conductivity leading to enhance the electrochemical signal and greater sensitivity for the detection of PSA.

Objective: The aim of the present study is to examine the relationship between EEG measures and functional recovery in right-hemisphere stroke patients.
Methods: Participants with stroke (PS) and neurologically unimpaired controls (UC) were enrolled. At enrolment, all participants were assessed for motor and cognitive functioning with specific scales (motricity index, trunk control test, Level of Cognitive Functioning, and Functional Independence Measure (FIM).

The preparation of food-grade oxidized starch with eco-friendly ozone (O) as oxidant is limited by low mass transfer and reaction efficiency. This study proposed a porous spontaneously polarized ceramic-reinforced O micro-nano bubbles (PSPC-OMNB) technology to prepare oxidized cassava starch (PSPC-OMCS). Meanwhile, reaction uniformity, physicochemical properties, and formation mechanisms were emphasized for comprehensive investigation.

Organic field-effect transistors (OFETs) integrated with commercial transistors are promising sensing platforms characterized by enhanced device uniformity, functional diversity, and electrical output stability. Aptamers with charged backbones and a high affinity for target molecules are anticipated to mitigate the limitations imposed by Debye screening in physiological environments with high ionic strength, thereby facilitating specific biological recognition in complex surroundings. This study presents two reliable OFET aptasensors for vascular endothelial growth factor (VEGF) and offers a systematic comparison of their performance.

An accurate assessment of leachate levels necessitates the integration of various parameters. Traditional geophysical prospecting methods often lack measurable accuracy because they focus on individual parameters rather than effectively integrating data. This may lead to inconsistent estimates of leachate depth and make the evaluation of prediction reliability challenging.
