Abstract Development of food detection strategies provides chances for the determination of
contaminants in foodstuffs. Optical detection approaches which are based on light …

Nucleic acids are remarkable molecules. In addition to Watson–Crick base pairing, the
different structural motifs of these molecules can bind non‐nucleic acid targets or catalyze …

Fast, inexpensive, and multiplexed detection of multiple nucleic acids is of great importance
to human health, yet it still represents a significant challenge. Herein, we propose a nucleic …

Pen‐side testing of farm animals for infectious diseases is critical for preventing transmission
in herds and providing timely intervention. However, most existing pathogen tests have to be …

Molecular recognition at the biointerface plays a critical role in sensing molecular
interactions (eg, DNA hybridization) and extracellular changes, which can directly affect the …

Fast and accurate detection of microbial cells in clinical samples is highly valuable but
remains a challenge. Here, a simple, culture‐free diagnostic system is developed for direct …

The concept of color in chemistry can take us back to when the separation of color-based
natural products, dyes, and other chemical compounds led to the technique called …

DNAzyme-based electrochemical biosensors provide exceptional analytical sensitivity and
high target recognition specificity for disease diagnosis. This review provides a critical …

Infectious diseases (such as sepsis, influenza, and malaria), caused by various pathogenic
bacteria and viruses, are widespread across the world. Early and rapid detection of disease …

There are various pathogenic bacteria in the surrounding living environment, which not only
pose a great threat to human health but also bring huge losses to economic development …
