Results from this first-generation study suggest that a more accurate estimate of total energy intake is provided when combining the use of a conventional food diary and a SenseCam. Additional information on portion size, forgotten foods, leftovers, and brand names can be obtained by using this novel sensing technology in conjunction with the diary, with improved dietary assessment a potential outcome.

The current work is amongst the first to examine the potential usefulness of the nitrile functional group in potentiometric analytical sensors for soft metals. Nitrile functionality has hereby been incorporated into a calix

Since their discovery as by-products in the phenol-formaldehyde condensation to prepare bakelites, the calixarenes have gained much attention for their application as both surfactants and chemoreceptors. The McKervey group has been a leader in the development and synthesis of new and novel calixarenes for use as ion-complexing agents as well as for use in many other applications. Many calixarene derivatives prepared by the McKervey group are being used in both environmental and biomedical monitoring. This review covers both the synthesis and sensor applications of the various calixarenes developed by the McKervey group over the past two decades, with emphasis on metal cation detection.
