Oligonucleotide probes articles from across Nature Portfolio

Detecting genetic mutations, such as single nucleotide polymorphisms (SNPs), is essential for disease diagnostics but can be difficult using homomultivalent DNA hybridization-based approaches. Now, heteromultivalent hybridization is used to fine-tune binding specificity for the detection of one or two SNPs in a single target, enabling straightforward discrimination between adjacent and distant mutations and different viral strains.

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.

GlycoRNA imaging in cells is enabled with a proximity ligation assay.

Sensing changes in ionic current as barcoded DNA translocates through solid-state nanopores allows the study of how nucleotide sequences alter the DNA-binding specificity of the catalytically inactive Cas9 ribonucleoprotein complex.

DNA-PAINT with left-handed DNA oligomers enables imaging of nuclear structures with reduced background.
