Summary: In this study, an electrochemical biosensor based on a screen-printed carbon electrode was developed for the rapid detection of human noroviruses (HuNoVs). The biosensor showed high sensitivity and specificity, and could detect different genogroups and genotypes of HuNoVs. The detection limit of HuNoVs in clinical fecal samples was 10(4) genomic copies/mL. The results could be obtained within 1 hour.

Summary: Polypyrrole-based electrodes with desired pseudocapacitive storage capabilities have been widely studied, but their utilization in flexible supercapacitor electrodes has been limited. In this study, a surface-modified thermoplastic polyurethane (TPU) was used as a flexible substrate and coated with carbon nanotubes (CNTs) to improve conductivity and interface with PPy nanofoam (PPyNF) structures. The resulting TPU/CNT/PPyNF electrodes demonstrated good flexibility and charge storage capability.

Summary: This study investigates the degradation of environmental DNA (eDNA) and environmental RNA (eRNA) under different pH conditions. The results show that eRNA decays more rapidly than eDNA, and eDNA degrades more slowly under acidic conditions. This study provides a basis for assessing the persistence and degradation dynamics of eRNA and eDNA under ecologically relevant pH conditions.

Summary: An innovative 2D/0D g-C3N4/CeO2 nanostructure was synthesized using a simple precursor decomposition process. The nanostructure exhibited a capacitance of 202.5 F/g, remarkable rate capability, and stability, surpassing the performance of g-C3N4 electrode. The combination of g-C3N4 and CeO2 quantum dots also enabled an asymmetric device with the highest energy density (9.25 Wh/kg) and power density (900 W/kg).

Summary: An electrochemical aptasensor based on tetrahedral DNA nanostructures was developed for the highly sensitive detection of FB1 at sub-fg mL(-1) levels with a dynamic range of 7 orders of magnitude. The use of TDN as a substrate for FB1 aptamer anchoring allowed for controllable and stable assembly, enhancing sensor sensitivity and extending dynamic range. The sensor exhibited a linear dynamic range of 0.500 fg mL(-1) to 1.00 ng mL(-1) with a detection limit of 0.306 fg mL(-1), showcasing its applicability and reliability in FB1 detection in rice samples.
