2014 Insights Issue

Guest editor, George Whitesides, introduces this series of Insights in Lab on a Chip’s 200th editorial.

Collectively, these Insights demonstrate how the emphasis in LOC science and technology is shifting from foundational areas, such as methods of micofabrication and the physics of microscale flows, to serious explorations of uses and to demonstrations of applications. It is this research that provides the incentive for further and more extensive industrial engineering development and ultimately the incorporation into products. We hope you enjoy reading the collection as much as we did.

200th Issue of Lab on a Chip

We are delighted to announce the publication of our 200th issue of Lab on a Chip- how we have grown!

Launched in 2001, publishing 2 issues with a total of 31 articles that year, LOC is now publishing 24 issues a year. Many of the young researchers that published in the first issue have now become Professors themselves, and many have gone on to become award winners. Read the full editorial by our Editor, Harp Minhas to find out more!

This picture shows how the image of LOC has developed from the original cover to the LOC we are familiar with today.

To celebrate this achievement, we have made all of the HOT articles in the 200th issue of LOC free* to access throughout August. Click on the links below to download.
