Chemical contamination in food is one of the most serious food safety problems. Competitive
enzyme-linked immunosorbent assay (Cp-ELISA) is the most widely used analytical tool for …

Nucleic acid‐based hydrogels that integrate intrinsic biological properties of nucleic acids
and mechanical behavior of their advanced assemblies are appealing bioanalysis and …

Traditional diagnosis of infectious diseases relies on advanced analyzers in central
hospitals, which is not sufficient for rapid control of epidemics, especially in resource-limited …

Milk contaminated with trace amounts of foodborne pathogens can considerably threaten
food safety and public health. Therefore, rapid and accurate detection techniques for …

Bi-detection of chemical risks in different kinds exhibited an increasing significance for food
security considering their general concurrence and synergetic toxicity. In this study, a simple …

Enzyme-linked immunosorbent assay (ELISA) is an ideal immunoassay technique for large
scale screening detection of various chemical contaminants in food due to its high …

Here, we constructed a fast, universal,“turn-on” biosensor for the highly sensitive visual
detection of Salmonella based on luminescent DNAzyme and a universal blocking linker …

In this study, an isothermal paper biosensor, combining single universal primer recombinase
polymerase amplification (SUP-RPA) and the lateral flow technique was developed for the …

Polymerase chain reaction (PCR) is an excellent technique for amplifying DNA. It is worth
studying to expand the application of PCR to detect other targets besides DNA. In this work …

The advantages of rapid amplification of nucleic acid without a template based on terminal
deoxyribonucleotidyl transferase (TdT) have been widely used in the field of biosensors …
