Efforts to make the particles smaller have worked, but have raised safety concerns because they can penetrate the skin and potentially interact with cells.
Moving around unseen are an estimated 500, 000 particles ranging in size between 1-10cm across, and perhaps tens of millions of other particles smaller than 1cm.
Respiratory health researches have for years suspected a relationship between raised levels of particulate matter (defined as airborne particles smaller than 2.5 micrograms) and cardiac arrest.
FORBES: Researchers Prove Air Pollution Causes Heart Attacks
Last year Monterrey, the country's industrial capital, clocked a higher reading than Mexico City on its index of particles smaller than 10 microns, a form of pollution that is no less dangerous than ozone.
ECONOMIST: The capital��s filthy atmosphere has improved at last
"As humans we can identify galaxies light years away, we can study particles smaller than the atom, but we still haven't unlocked the mystery of the 3lb of matter that sits between our ears, " he said.
Mr Zimmet said these smaller particles may deliver the insulin in the more accessible monomer form.
During this ongoing process it separates into smaller and smaller particles, therefore increasing its initial surface area.
It has been known since the 1960s that protons are made of smaller particles called quarks and gluons.
The sample is incubated with platelets and exposed to repeated rounds of ultrasound, which break the prions up into more numerous smaller particles.
They are why scientists continually reform their theories, and why we continuously find smaller and smaller particles that define how our universe works.

One mystery yet to be solved is why people with Syndrome X have smaller particles of low density lipids, the type of cholesterol most likely to block arteries.
High speed proton collisions generate a range of even smaller particles that scientists have been sifting through in search of a signal in the data suggesting the existence of the Higgs boson.
The agency has begun a second test, which will be completed in January 2012, measuring the volume of smaller particles, which could go deeper into the lungs and cause more extensive damage if breathed in.

Ranbaxy has reported that certain lots of their 10, 20, and 40 milligram tablets contain glass particles, bits that are smaller than 1 mm in size.
The membrane started out very leaky, but over time, the membranes would have slowly closed, preventing much larger sodium particles from leaving the cell while smaller protons could still slip through.
If properly fitted and worn correctly, N95 respirators filter out at least 95 percent of particles as small as 0.3 micrometers, which is smaller than influenza viruses, the report notes.
CNN: Report on handling H1N1 cases: Use masks with airtight seals
He explained that ground-based radars are able to track objects of about 10cm (3.9 inches) and sometimes smaller, depending on altitude above the earth, while other sensors can detect particles down to about 5mm (0.2 inches) in low earth orbit.
