Electrochemical sensors provide an affordable and reliable approach towards the detection and monitoring of important biological species ranging from simple ions to complex biomolecules. The ability to miniaturize electrochemical sensors, coupled with their affordability and simple equipment requirements for signal readout, permits the use of these sensors at the point-of-care where analysis using non-invasively obtainable biofluids is receiving growing interest by the research community. This paper describes the design, fabrication, and integration of a 3D printed Mg potentiometric sensor into a 3D printed microfluidic device for the quantification of Mg in low-sample volume biological fluids.

- * I-131 scans are essential for monitoring thyroid remnants, residual disease, and potential recurrences, relying on the sodium-iodide symporter for iodine uptake.
- * This review discusses cases from our department where false-positive I-131 uptake occurred in conditions like vertebral hemangioma, lipoma, sinusitis, teratoma, and uterine leiomyoma.
A Rare Finding of Pancreatic Involvement in a Case of Burkitt's Lymphoma.
Indian J Nucl Med

Burkitt's lymphoma (BL) is a highly aggressive type of B-cell non-Hodgkin lymphoma. BL commonly occurs in children of age 4-7 years and is uncommon in adults, with a worse prognosis. Patients often present with a rapidly growing mass typically involving the abdomen (liver and spleen) and head and neck (nodes, jaw, and facial bones).

- Bifunctional electrocatalysts like the defect-rich nitrogen and sulfur co-doped graphene/iron carbide (NS-GR/FeC) nanocomposite are crucial for improving performance in metal-air batteries and fuel cells by facilitating efficient oxygen reduction and evolution reactions.
- An innovative preparation method using ultrasonication creates a stable ink of NS-GR/FeC, which is then utilized to make electrodes for electrochemical testing.
- The NS-GR/FeC electrode shows impressive performance metrics, with positive half-wave potential for oxygen reduction at 0.859 V and onset potential for oxygen evolution at 1.489 V, marking it as a strong low-cost alternative to traditional noble metal catalysts for energy applications.
To dates, the facile synthesis of inorganic-coated organic polymer composite has received greater attention in the order of research fields including advanced materials and electrochemical analysis owing to the complementary or synergistic effects. In this context, PrO and PrO coated polystyrene (PrO/PS) inorganic-organic colloidal composite were prepared via ultrasound-induced radicals initiated precipitation and dispersion polymerization methods. The synthesized PrO/PS composite was systematically studied by FE-SEM, TEM, EDX, FT-IR, XRD, and XPS analysis.
