BACKGROUND: Pregnancy-associated plasma protein-A and -A2 (PAPP-A and -A2) are principally expressed in placental trophoblasts and play a critical role in the regulati...
Multiplexing allows quantifying multiple analytes in a single step, providing advantages over individual testing through shorter processing time, lower sample volume, ...
Norovirus is one of the leading causes of gastroenteritis, acute vomiting, intense diarrhoea, acute pain in the stomach, high fever, headaches, and body pain. Conventi...
Herein, we established a universal and sensitive plasmonic sensing strategy for biomolecule assays by coupling the hybridization chain reaction (HCR) strategy and a tr...
The invention of two-photon excitation microscopes widens the potential application of intravital microscopy (IVM) to the broad field of experimental pathology. Moreov...
A hybrid conjugate of reduced graphene oxide/ferrous-ferric oxide nanoparticles (rGO-Fe3O4 NPs) is characterized and assembled with chitosan and laccase to form a laye...
The assessment of water quality is critical to implement preventive and emergency interventions aimed to limit/avoid environmental contamination and human exposure to ...
Homogeneous electrochemical DNA biosensors' unique qualities have been of great interest to researchers, mainly due to their high recognition efficiency in solutions. ...
Genetic circuit-based biosensors have emerged as an effective analytical tool in synthetic biology; these biosensors can be applied to high-throughput screening of new...
Biosensors regulated by specific substrates are needed to develop genetic tools to meet the needs of engineering microbial cell factories. Here, a xylose-inducible bio...
Flavonoids represent a diversified family of phenylpropanoid-derived plant secondary metabolites. They are widely found in fruits, vegetables, and medicinal herbs. The...
The management of pathogen detection using a rapid and cost-effective method presents a major challenge to the biological safety of the world. The field of pathogen de...
A sensor is a device used to gather information registered by some biological, physical or chemical change, and then convert the information into a measurable signal. ...
Rapid industrialization and urbanization have resulted in serious environmental deterioration, especially in terms of heavy metal contamination in soil. Arsenic is one...
Research on contingency management is limited due to feasibility issues with monitoring adherence. Incentives usually depend on objective measures to verify compliance...
Herein, a simple all-in-one biosensor based on a DNA three-way junction has been constructed for in situ simultaneous detection of multiple miRNAs by competitive stran...
Single nucleotide polymorphisms (SNPs) are crucial during the early diagnosis of a given disease as well as in evaluating their response to certain drugs. Thus, this s...
With the large-scale planting of genetically modified (GM) crops, the development of a rapid and convenient method for on-site monitoring GM crops is needed. In this s...
In this study, a tunable biosensor using the localized surface plasmon resonance (LSPR), controlling the distance between fluorescent CdZnSeS/ZnSeS quantum dots (QDs) ...
DJ-1, a 20.7 kDa protein, is overexpressed in people who have bladder cancer (BC). Its elevated concentration in urine allows it to serve as a marker for BC. However, ...
