The prevention of pollution requires real-time monitoring of cadmium (Cd) concentration in the food, as it has a dramatic impact on poultry and can pose a threat to human health. Here, we fabricate a portable workstation integrating a microfluidic chip that facilitates real-time monitoring of Cd levels in real samples by utilizing the Luminol-KMnO chemiluminescence (CL) system. Interestingly, Cd can significantly enhance the CL signal, resulting in sensitive detection of Cd in the range of 0-0.18 mg/L with the limit of detection (LOD) of 0.207 μg/L. Furthermore, a remote-controlled unit is integrated into the portable workstation to form a remote-controlled portable workstation (RCPW) performing automated point-of-care testing (POCT) of Cd. The as-prepared strategy allows remote control of RCPW to avoid long-distance transportation of samples to achieve real-time target monitoring. Consequently, this system furnishes RCPW for monitoring Cd levels in real samples, thereby holding potential for applications in preventing food pollution.

The rapid pace of shotgun proteomics data generation presents challenges for timely data analysis. In parallel, the scientific community is creating novel data interpretation tools, such as artificial intelligence, that have not yet been integrated into commercial software. Off-site data processing with free and open-source software (FOSS) enables the decentralization and scaling of informatics workflows.

A decentralized electrochemical immunosensor was developed using a smartphone and a portable electrochemical workstation. The system employs a gold nanoflower-modified screen-printed carbon electrode (AuNFs/SPCE) for the sensitive measurement of adalimumab (ADL) in human serum via antigen‒antibody recognition. Scanning electron microscopy, X-ray photoelectron spectroscopy, and atomic force microscopy were used to investigate the AuNFs/SPCE.

The binding of oxalic acid (OA) with metal ions, particularly calcium ions, is a key factor in kidney stone formation, as it produces insoluble calcium oxalate, which crystallizes and accumulates in the kidneys. Consequently, OA in urine is commonly considered a significant biomarker for clinical diagnosis and early screening of kidney stones. This study reports churros-like VSe nanostructures synthesized using a solvothermal method (high pressure and temperature) for sensitive and selective electrochemical detection of OA in urine.

The development of portable, cost-effective, and highly sensitive biosensors for real-time biomarker detection is crucial for advancing point-of-care testing (POCT) and wearable health monitoring. Here, we present an integrated portable electrochemical sensor (ip-ECS) that combines gold nanoparticles (AuNPs) and MXene-modified screen-printed electrodes (SPEs) with a custom-designed, low-power electronic system for point-of-care monitoring of serum biomarkers. The AuNPs and MXene nanocomposite significantly enhances the electrochemical performance of the SPE by providing a high density of active sites, improved conductivity, and catalytic activity.
