Nanotechnology molecular tagging

A
novel technology of measuring concentrations of ionized
molecules in gases that enables detection of individual
ionized molecules by means of tagging them with readily
detectable nano-objects has been discovered, developed and
partially commercialised. It was found that Nanotechnology
Molecular Tagging (NMT) method where ions were tagged
with electrically neutral objects, e.g. nanoparticles with
radius 100 nm, can provide a breakthrough in sensitivity
by enabling a single molecular ion, electron or muon to
be detected. This provides an increase in sensitivity over
three orders of magnitude in comparison to existing
detection methods based on the Faraday cup/plate or
Mass Spectrometry. For example, the concentration of
ionized molecules of cocaine was measured and a detection
limit of 5 cm-
3
was observed. This concept opens doors
for advances in detection sensitivity in chemistry, biology,
medicine and physics. In medical applications and life
science the measurement of VOC biomarkers as a diagnostic
of cancer and infectious diseases is a rapidly growing area
of metabolomics that promises to bring a non-invasive
fast diagnostic to points of care. An increase in sensitivity
with NMT detector will enable diagnosis of earlier stages
of diseases and increase patient survival rate, e.g. for the
lung cancer from 20 to 80%. Detection of an ultra-low
concentration of VOCs is crucial for security applications to
identify explosives and illicit drugs in airports. Replacement
of Faraday cup sensors with NMT detectors enables the false
negative rate of detection to be considerably reduced and
also it improves customer experience.
Speaker Biography
Boris Gorbunov has been working in nanotechnology over 40 years. He has worked in
the UK, Finland, Russia and France. Currently he is a director of Ancon Technologies
Ltd. (Canterbury UK), Ancon Medical Inc. (Minneapolis MN), Naneum Ltd., (Canterbury
UK) and a Board Member of some other nanotechnology companies. He has over 150
publications and circa 600 citations. His RG score is 33.75. He is an inventor of the
NMT detection technology and the main driving force to commercialize and apply
it for the life science and medical diagnostic. He also has developed a new method
and instrumentation to evaluate adverse health effects of airborne nanoparticles. He
is a co-author of discovery of the surface controlled nucleation that was successfully
applied to characterise carcinogenic potential of nanoparticles.
