Biosensors articles from across Nature Portfolio

Biosensors are devices used to detect the presence or concentration of a biological analyte, such as a biomolecule, a biological structure or a microorganism. Biosensors consist of three parts: a component that recognizes the analyte and produces a signal, a signal transducer, and a reader device.

Intracellular RNA and DNA tracking by uridine-rich internal loop tagging with fluorogenic bPNA

Commonly used protein-based tools to monitor intracellular RNA and DNA can impact steric accessibility and native nucleic acid biology. Here, the authors show that fluorogenic uridine-rich internal loop tagging bPNA probes can be used to label nucleic acids in fixed and live cells.

A smart pathogen detector engineered from intracellular hydrogelation of DNA-decorated macrophages

Macrophages have the inherent capacity to recognise pathogenic microorganisms, highlighting their potential to be used in biosensing applications. Herein, the authors report a method to transform normally fragile macrophages into robust gelated cell particles for efficient bacterial capture and detection.

Near-infrared magnetic core-shell nanoparticles based on lanthanide metal-organic frameworks as a ratiometric felodipine sensing platform

Monitoring of the hypertension drug felodipine is important to avoid unwanted side effects from high concentrations, but its sensitive detection remains challenging. Here, combining the advantages of ratiometric luminescence probes and near-infrared lanthanide luminescence sensing, multi-emission near-infrared magnetic core-shell nanoparticles based on lanthanide metal–organic frameworks are synthesized using a layer-by-layer method and shown to have excellent temperature and felodipine detection abilities.
