The development of integrated multiple signal outputs within a single platform is highly significant for efficient and accurate on-site biomarker detection. Herein, colorimetric/electrochemical dual-mode microfluidic paper-based analytical devices (μPADs) were designed for portable, visual and accurate dopamine (DA) detection. The dual-mode μPADs, featuring folded structure, integrate a colorimetric layer and an electrochemical layer using wax printing and laser-induced graphene (LIG) pyrolysis techniques, allowing the vertical flow of analyte solution.

Background: Perception-related errors comprise most diagnostic mistakes in radiology. To mitigate this problem, radiologists use personalized and high-dimensional visual search strategies, otherwise known as search patterns. Qualitative descriptions of these search patterns, which involve the physician verbalizing or annotating the order he or she analyzes the image, can be unreliable due to discrepancies in what is reported versus the actual visual patterns.

International medical graduates (IMGs) represent a significant portion of the US physician workforce, comprising 25% across all specialties with a strong presence in internal medicine and primary care. However, their representation in plastic surgery remains limited at only 10%. Matching into a US plastic surgery residency is highly competitive for both US medical graduates and IMGs.

Flexible electronics have been rapidly advancing and have garnered significant interest in monitoring physiological activities and health conditions. However, flexible electronics are prone to detachment in humid environments, so developing human-friendly flexible electronic devices that can effectively monitor human movement under various aquatic conditions and function as flexible electrodes remains a significant challenge. Here, we report a strongly adherent, self-healing, and swelling-resistant conductive hydrogel formed by combining the dual synergistic effects of hydrogen bonding and dipole-dipole interactions.

Developing heavy-metal-free materials with wide tunable emission is important to light-emitters. The alloying method is utilized in ZnSe magic size clusters (MSCs) with Te to form ZnSeTe and manipulate the band gap structure in ZnSe. The growth of ZnTe on alloyed ZnSeTe quantum dots (QDs) forms ZnSeTe/ZnTe core/shell nanostructures, showing the tunable photoluminescence emission peak from 450 to 760 nm with the different thicknesses of ZnTe shell.
