DNA can be analyzed by many techniques, including electrophoretic techniques such as gel, capillary, and microchip electrophoresis. In this interview Kevin Dorfman, an Associate Professor in the Department of Chemical Engineering and Materials Science at the University of Minnesota in Minneapolis, Minnesota, USA, discusses his research with polymer physics and microfluidic and nanofluidic technologies.

A new study published in the Journal of Chromatography A presents a sensitive method for the quantification of apidaecins, a type of antimicrobial peptide that play an important role the immune response of honey bees to pathogens. The method was developed using reversed-phase nanoliquid chromatography coupled with high resolution mass spectrometry (LC–MS) to determine apidaecins in hemolymph or body parts from individual honey bees.
