Esmeralda Herrero BSc. PhD


Esmeralda Herrero graduated from University College Dublin (UCD) with a BSc in Pharmacology and completed a PhD in Microbiology in University College Dublin. Her research investigated bacterial proteases and their role in prion decontamination and was filed into a UK patent in 2015. Following her PhD, Esmeralda worked for a year as research and development scientist for a novel biotech company before her role as scientific officer in virology in airmid healthgroup.

Esmeralda has over 5 years research experience in mammalian cell culture, molecular biology, bacterial culturing, infectious assays, protein purification, protein biochemistry and laboratory management


Tristan Russell BSc. PhD


Tristan graduated from the University of Leeds with a BSc in Microbiology. During his degree, Tristan completed a one-year internship at a pharmaceutical company where he gained experience of working in an industrial laboratory. Tristan moved to Ireland in 2014 after choosing to study for a PhD at University College Dublin. The PhD research used molecular biology techniques to study infectious disease, specifically host-virus interactions. Tristan recently graduated from his PhD and joined the virology team at airmid healthgroup in the spring of 2019.

Kevin is in his third year at DCU where he has been studying Genetics and Cell biology. He is working in the Environmental Chambers under the supervision of Jake Behan.


Airborne Microbial Vacuum Cleaner Test

Description of Test

Determines the impact of a vacuum cleaner system on airborne microbes, mold, viruses, ultrafine particles and other airborne pathogens using PCR and other aerobiological testing

Products that can be tested
Household and commercial canister (tank-type), stick, hand-held, upright, and utility vacuum cleaner systems.


The emission of ultrafine particles from certain vacuum cleaners, even with HEPA based filtration, can result in consumer exposure to bacterial fragments, and other noxious particulate materials.

Household dust comprises of bacteria, viruses, mold and toxins.  Most microorganisms are of sub-micron particulate size. When dust in a room is disturbed, these particles remain airborne for days at a time. Recirculation of the contaminated air serves to augment exposure and hence potential infectivity.

airmid healthgroup is a uniquely integrated testing facility which combines molecular biology with state of the art air sampling and particle counting in a highly sophisticated environmental test chamber. Availing of such facilities, we can follow nominated airborne infectious agents and other toxic biological particles, such as ultrafine particles, as they become airborne and are distributed throughout the chamber in the presence and absence of the vacuum cleaner under test.

Aerobiological data generated in this manner will have a vastly greater degree of sensitivity and specificity than any that relies on conventional techniques. Molecular technology also allows for quantification of residual contamination within the vacuum cleaner and its ability to capture any infective biological particulate material being shed.

airmid healthgroup's previous work and applied research in microbiology, molecular biology, and aerobiology means we we are uniquely positioned to provide this service.
