We are very pleased to announce a new Analyst themed collection focusing on optical biosensor devices, guest edited by Associate Editors Ryan Bailey, Jaebum Choo, Laura Lechuga, Baohong Liu and Advisory Board member Chaoyong James Yang.

Optical biosensors have positioned themselves as one of the most successful branches of biosensor devices. The rapidly expanding of the field of optical biosensors has been possible thanks to the continuous progress is nanomaterials and nanostructures, new types of physical supports together with advanced biofunctionalization techniques, new receptors and demonstration of their applications for analyzing minimum-treated real samples, making them one of the most advanced and competitive sensing tool. The application scope of optical biosensors are wide-ranging and very diverse, including environmental, clinical, agriculture, veterinarian and security and rapidly expanding to diagnostics in resource-limited settings and personalised medicine.

The aim of this themed collection issue is to cover recent development of sensor devices combining with diverse optical detection methods. The issue will bring together the last developments in: innovative optical technologies at the transducer scheme, new nanomaterials and nanostructures, hybrid devices, improvement of sensitivity, miniaturization and multiplexing capabilities, microarray formats, sensors based on optofluidics, lab-on-chip and point-of-care platforms, new routes of biofunctionalization, single-molecule detection, covering the full spectrum of possible applications for optical biosensors.

We invite submissions of articles or reviews on topics across this theme.

Accepted articles will be collated into an online collection as soon as they are accepted and in the themed collection as a whole and will be promoted as a complete collection in Autumn/Winter 2020.

The submission deadline for this collection is 30^th April 2020.

If you’re interested in submitting to the collection, please contact the Editorial Office.

We have compiled a collection of recent papers and reviews published in Analyst on this topic. Below is a selection of these articles. The rest can be read here and are available free to access* until 15^th November.
