Summary: A plug-and-play sandwich assay platform utilizing linear dichroism spectroscopy as a read-out method was developed for aptamer-based detection of molecular targets. The platform involved conjugating a 21-mer DNA strand onto the backbone of filamentous bacteriophage M13, generating a strong LD signal. Extended DNA strands containing thrombin-binding aptamer sequences were then bound to the linked DNA strand, creating aptamer-functionalized M13 bacteriophages. The sandwich sensor design showed effective detection of thrombin at pM levels, demonstrating the potential of this label-free assay system.

Summary: Schistosomiasis affects over 240 million people worldwide. Detecting the parasite eggs using Kato-Katz method is specific but not sensitive, while the urine-based POC-CCA test is more sensitive but has specificity issues and interpretation challenges. This study explores the variation in test results and suggests different thresholds for accurate diagnosis and prevalence monitoring.

Summary: Globally, 70 million people are affected by traumatic brain injury (TBI) annually. Diagnosis of mild TBI (mTBI) is challenging due to the absence of apparent symptoms. Current diagnostic methods rely on patient history, clinical aspects, and neuroimaging observations, which are costly and time-consuming. As an alternative, mTBI diagnostics can be done by detecting biomarkers in patients' blood. This study proposed two strategies for detecting mTBI biomarkers using electrochemiluminescence (ECL) immunoassay. Multiplex assays on a single disposable screen-printed carbon electrode (SPCE) were also developed. The methodology presented demonstrates the feasibility of a rapid point-of-care (POC) multiplex diagnostic system for mTBI biomarkers.

Summary: Brazil is home to venomous snakes, with Bothrops genus being medically relevant. Bothrops spp. account for 70% of all snakebites in Brazil, and their envenomings can be treated with three types of antivenom. This article introduces a prototype of a lateral flow assay (LFA) capable of detecting venom from Brazilian Bothrops spp. The LFA shows potential in diagnosing Bothrops envenomings and could improve snakebite management in the highly neglected disease.

Summary: A facile amperometric biosensor was developed using a Co/2Fe metal-organic framework (MOF) with oxidase mimicking properties for the detection of sialic acid (SA). The biosensor was constructed by immobilizing Co/2Fe MOF and N-acetylneuraminic Acid Aldolase (NANA-Aldolase) enzyme on a gold screen-printed electrode. The sensor showed a linear range of 0.02 mM-1.00 mM for SA concentration and a limit of detection of 0.026 mM. The developed biosensor was successfully applied for the detection of SA in GD3 ganglioside and HeLa cancer cell lines, providing a more practical and accurate system.

Summary: Minimally invasive approaches in cancer diagnosis, such as liquid biopsies using blood samples, provide valuable information about the tumor and its state. However, isolating and detecting markers in complex matrices is challenging. Advances in polymer synthesis have led to enhanced platforms for liquid biopsies analysis, improving biosensor performance through increased sensitivity, improved binding, and avoidance of non-specific interactions. Additionally, polymer-based materials aid in signal amplification for low-concentration targets. This technology plays an essential role in oncology and clinical biomedicine, as shown by its critical application in liquid biopsies diagnosis.
