**Preface to "Microfluidics for Biosensing and Diagnostics"**

We are pleased to present this Special Issue on sensing and diagnostics with microfluidics. Efforts to miniaturize sensing and diagnostic devices and to integrate multiple functions into one device have caused massive growth in the field of microfluidics and this integration is now recognized as an important feature of most new diagnostic approaches.

The field of microfluidics is exceptionally diverse. It attracts interest and contributions from physicists, chemists, and biologists as well as electrical, mechanical, chemical, and biomedical engineers. Working in such a diverse community poses many challenges arising from different training, different terminology, and different standards and expectations for data. This brief collection of papers highlights the spread of expertise that is involved in research aimed at developing biosensing and diagnostics using microfluidics.
