Our research group has previously demonstrated the ability to detect bacteria within numerous types of biological media to a high degree of accuracy using laser-induced breakdown spectroscopy (LIBS). This presentation will describe our efforts to differentiate several bacterial species using this spectroscopic method in addition to detection. Experiments were conducted on Escherichia coli,...

Radon (222Rn) is a naturally occurring radioactive noble gas. It is purported to be the second leading cause of lung cancer in Canada and the USA. Exposure is currently assumed to be confined to the respiratory epithelium following inhalation. However, as an inert gas, radon may diffuse into porous media, water, and possibly biological soft tissues. Direct measurements of radon movement in and...

Mechanically-stimulated bioluminescence in Pyrocystis fusiformis acts as a signal for probing environmental health using time-correlated single-photon counting techniques. The York University PCS 121, a portable biosensing technique utilizing Silicon Photomultiplier (SiPM) technology, in which a mechanical stimulus triggers the bioluminescence reaction, was used to measure photon emission...

Crosslinking of collagen is a critical mechanism in bioengineering and human health. Crosslinks are used to strengthen in-vitro assembled collagen materials, yet excessive crosslinking in-vivo, due to factors such as aging and high blood sugar, can lead to functional loss in human tissues. There is a lack of understanding regarding the effects of crosslinking on collagen molecular...

Phytoglycogen (PG) is a natural biopolymer extracted from sweet corn that is composed of highly branched chains of glucose molecules. Its special dendritic chain architecture results in monodisperse nanoparticles with a diameter of 42 nm that are decorated with short chains, and its chemically simple composition results in biodegradability and nontoxicity. This combination of properties makes...

The ear is a complex system that acts as a mechanoelectrical transducer, allowing organisms to sense acoustic signals emanating from the world around them. To improve its ability to detect sound, the ear is active in that it uses metabolic energy to generate force that counteracts both frictional forces and noise (e.g., viscous and thermal properties of the inner ear fluid). The healthy...
