Exploring the influence of ion heating on the accuracy of collision cross-section measurements using a traveling-wave ion mobility device

Ion mobility-mass spectrometry measurements are regularly used in biological chemistry for many applications.  This hot paper from Brandon Ruotolo and colleagues provides useful descriptions of important experimental parameters that affect ion mobility resolution and overall performance, and links this to theory.  One referee commented that this will “be a very useful paper especially to students and researchers who will be using the new generation IM-MS instruments”.

This paper will be included in a themed issue on Emerging Investigators, Guest Edited by Perdita Barran and Christy Haynes, to be published later this year.

Scheme representing a hydrogel and two modes of incorporating bio-responsive properties.

Read Sean Bird and Lane Baker’s Minireview on of the use of responsive hydrogels in chemical sensing which will be free to access until 1st March.

It includes a discussion of available methods for assimilating an assortment of biological molecules into hydrogel matrices to act as recognition elements for bio-responsive sensors.
