Prof Dermot Diamond

Biography

Dermot Diamond received his Ph.D. and D.Sc. from Queen’s University Belfast (Chemical Sensors, 1987, Internet Scale Sensing, 2002), and was Vice president for Research at Dublin City University (DCU), Ireland (2002-2004).

He has published over 180 peer reviewed papers in international science journals, is a named inventor in 13 patents, and is co-author and editor of three books, ‘Spreadsheet Applications in Chemistry using Microsoft Excel’ (1997) and ‘Principles of Chemical and Biological Sensors’, (1998) both published by Wiley, and ‘Smart NanoTextiles’, Materials Research Society Symposium Proceedings, Volume 20, 2006.

Professor Diamond is currently director of the National Centre for Sensor Research at DCU (www.ncsr.ie) and a Principal Investigator with the Adaptive Information Cluster (AIC), a major research initiative in the area of wireless sensor networks founded by Science Foundation Ireland (see www.adaptiveinformation.ie). He was formerly the vice-president for research at DCU (2002-2005). He is a member of the editorial advisory board of the international journal ‘Talanta’. In 2002 he was awarded the inaugural silver medal for Sensor Research by the Royal Society of Chemistry, London, and in 2008 he was received the DCU President’s Research award. Details of his research can be found at http://www.dcu.ie/chemistry/asg/.

Research Expertise

His research interests are broad, ranging from molecular recognition, host-guest chemistry, ligand design and synthesis, electrochemical and optical chemical sensors and biosensors, lab-on-a-chip, sensor applications in environmental, clinical, food quality and process monitoring, development of fully autonomous sensing devices, wireless sensors and sensor networks. He is particularly interested in the using analytical devices and sensors as information providers for wireless networked systems i.e. building a continuum between the digital and molecular worlds.

All-solid-state sodium-selective electrode based on a calixarene ionophore in a poly (vinyl chloride) membrane with a polypyrrole solid contact
  Aodhmar Cadogan, Zhiqiang Gao, Andrzej Lewenstam, Ari Ivaska, Dermot Diamond      1992      Analytical Chemistry

Sodium-selective coated wire electrodes (CWE) and solid contact (SC) electrodes have been constructed and Inves-tigated. The CWE Is based on the application of a poly (vinyl chloride)(PVC) membrane Incorporating the sodium-selective Ionophore tetraethyl ester of p-/erf-butylcallx [4] arene onto the surface of a platinum disk. The SC electrode Is based on the use of a conducting polymer, polypyrrole (PPy), doped with NaBF «as the mediating layer between platinum and the same PVC membrane as above. Nernstlan responses have been obtained for both electrodes and comparable selectlvlties to that of a conventional lon-selectlve electrode (ISE) based on the same Ionophore. Impedance measurements of the PPy and PVC layers and potentlometrlc studies of the membranes have been used to Investigate the mechanism of the charge transfer of the systems.

 

Wireless sensor networks and chemo-/biosensing
  D Diamond, S Coyle, S Scarmagnani, J Hayes      2008      Chemical Reviews

The concept of ‘wireless sensor networks’ or WSNs is relatively new, probably less than 10 years old, and a logical extension of the greater ‘networked world’through which a large proportion of the world’s population is already connected, for example, through mobile phones and other digital communication platforms. It envisages a world in which the status of the real world is monitored by large numbers of distributed sensors, forming a sensor ‘mesh’, that continuously feeds data into integration hubs, where it is aggregated, correlations identified, information extracted, and feedback loops used to take appropriate action. The entire system, in its ultimate manifestation, will be composed of interlocking layers of sensors that can be characterized in terms of their fit into a hierarchical model based on complexity (and therefore dependability) with feedback equally divided into layers of complexity (eg, local vs aggregated …

 

Development of a smart packaging for the monitoring of fish spoilage
  C McDonagh, BD MacCraith, AK McEvoyAlexis Pacquit, June Frisby, Danny Diamond, King Tong Lau, Alan Farrell, Brid Quilty, Dermot Diamond      2007      Food Chemistry

There is much interest from the fisheries industry in developing rapid methods to evaluate real-time freshness of fish and seafood products. Emphasis is on the ones that would reflect and account for the products history and their storage conditions from “harvest-to-home”. The development of a “smart packaging” that monitors the microbial breakdown products in the headspace of packaged fish is described. When fish spoils it releases a variety of basic volatile amines which are detectable with appropriate pH indicating sensors. These are prepared by entrapping within a polymer matrix a pH sensitive dye that responds, through visible color changes to the spoilage volatile compounds that contribute to a quantity known as total volatile basic nitrogen (TVB-N). Laboratory trials on fresh fish filets showed that the sensor accurately tracks the increase in amines concentration in the package headspace. The response was also found to correlate to changing microbial populations (total viable count or TVC and Pseudomonas spp.). In addition, leaching of the dye was assessed over time to assess the suitability of the sensor formulation for food packaging application.
