Multiplexed detection of biomarkers in lateral-flow immunoassays

Multiplexed detection of biomarkers, i.e., simultaneous detection of multiple biomarkers in a single assay, can enhance diagnostic precision, improve diagnostic efficiency, reduce diagnostic cost, and alleviate pain of patients.

Rapid and specific duplex detection of methicillin-resistant Staphylococcus aureus genes by surface-enhanced Raman spectroscopy

A highly specific method for rapid detection of MRSA genes has been proposed by combining surface-enhanced Raman spectroscopy nanotags and magnetic isolation, which shows great potential for accurate identification of MRSA at an early-diagnosis stage.

A rapid dual-channel readout approach for sensing carbendazim with 4-aminobenzenethiol-functionalized core–shell Au@Ag nanoparticles

In this study, a 4-aminobenzenethiol-functionalized silver-coated gold nanoparticle (Au@Ag-4ABT NP) system was designed for the rapid sensing of carbendazim (CBZ) using a combination of naked-eye colorimetry and SERS dual-channel approach.

About this collection

Professor Faulds has looked back at SERS papers published in Analyst over the last few years, and highlighted some of the most exciting and outstanding contributions for her Editor’s Choice collection. She adds that “it was very challenging to select this collection of representative articles due to the high number of excellent SERS articles published in Analyst. I hope you enjoy reading these articles as much as I did, and that these demonstrate the breadth and depth of SERS research published in Analyst; from multiplexed bioassays to imaging to SESORS.
