The smell-seeing approach differs from several other commercial and experimental designs for artificial noses
, which largely rely on polymers that swell when they come in contact with a vaporized chemical.
As a medical screening method, the artificial nose
will become a very useful tool.
Unlike other technologies used in artificial noses
, smell-seeing is not affected by changes in relative humidity.
The basic workings of an artificial nose
are quite simple.
According to David Walt, professor of chemistry, the concentrations of material the artificial nose
now can sense are in the several parts per million range for some substances.
Such an array could serve as an artificial nose
, sensing a variety of substances without using a lot of power.
CogniScent has granted Hamilton Thorne worldwide exclusive marketing rights in key market areas and the companies are working together to produce the next generation of novel sensors that will greatly increase the capability and sensitivity of artificial nose
Schmidt Professor of Chemistry at the University of Illinois at Urbana-Champaign, and his colleagues have created what they refer to as an optoelectronic nose, an artificial nose
for the detection of toxic industrial chemicals (TICs) that is simple, fast, inexpensive, and works by visualizing colors.
One could even make an artificial nose
to sniff out pollutants, allergens, [or] pathogens in the air to tell if the air quality around you is good or bad," Rothschild speculates.
Rodriguez believes the receptors could ultimately be incorporated into an artificial nose
that would detect illness.
To accomplish this, I propose to 1) build libraries of hybrid gels with semi-selective and selective properties, 2) generate odorant specific peptides mimicking olfactory receptors, 3) fully characterise the gels, 4) assemble artificial noses
for analysis of microbial volatiles, 5) create databases with organism-specific signal signatures, 6) identify pathogenic bacteria, including those with acquired antimicrobial-resistances.
The topics this year include artificial noses
, multiscale cancer modeling, bioengineering heart muscle as a paradigm for regenerative medicine, mapping fetal brain development in utero using magnetic resonance imaging, non-thrombogenic approaches to cardiovascular bioengineering, and the in vivo delivery of RNAi with lipid-based nanoparticles.
