Biomechanical Sensing Using Gas Bubbles Oscillations in Liquids and Adjacent Technologies: Theory and Practical Applications

“…Bubbles can also be electrogenerated in nonaqueous media such as methanol, ethanol, ethylene glycol, acetone and other solvents [ 240 ]. An extended discussion of these methods can be found in [ 241 ].…”

“…Although the intensity of sonoluminescence is rather low compared to that used in the well-established optical sensing methods such as fluorescence spectroscopy, it has been argued that the light emitted by collapsing bubbles can be exploited to non-invasively photo-activate drugs inside a living body or a biological cell [ 244 ]. Moreover, recent studies [ 33 , 240 , 241 ] proposed several novel approaches to further enhance sonoluminescence light intensity to a level detectable by standard equipment. In particular, the presence of nanoparticles, which does not affect the acoustic properties of a bubble, amplifies sonoluminescence by fluorescence-like [ 240 , 241 ] and plasmonic [ 33 ] effects.…”

“…An acoustic pressure wave with the frequency and peak amplitude that are similar 1000 to those of ultrasound waves used in medical ultrasound procedures drives bubble drugs inside a living body or a biological cell [239]. Moreover, recent works [24,240,241] 1026 proposed several novel approaches to further enhancement of sonoluminescence light 1027 intensity to a level detectable by standard equipment. In particular, the presence of 1028 nanoparticles, which does not affect acoustic properties of a bubble, amplifies sonolumi-1029 nescence by fluorescence-like [240,241] and plasmonic [24] effects.…”
