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.
