Apparent attenuation by opto-acoustic defocus in phonon microscopy

Photoacoustics, 2020
Understanding the mechanical properties of biological cells is a challenging problem for the life sciences partly because there are limited methods for mapping elasticity with high resolution.

Quantitative ultrasound biomicroscopy for the analysis of healthy and repair cartilage tissue [PDF]

European Cells & Materials, 2010
The increasing spectrum of different cartilage repair strategies requires the introduction of adequate non-destructive methods to analyse their outcome in-vivo, i.e. arthroscopically. The validity of non-destructive quantitative ultrasound biomicroscopy (

Mode specific dynamics for the acoustic vibrations of a gold nanoplate

Photoacoustics, 2023
The vibrational modes of semiconductor and metal nanostructures occur in the MHz to GHz frequency range, depending on dimensions. These modes are at the heart of nano-optomechanical devices, and understanding how they dissipate energy is important for ...

NDT techniques. Acoustic microscopy and holography [PDF]

, 2022
Vol.6Acoustic waves can penetrate into materials, and thus it is possible to study the microstructure of materials, detect small defects, study adhesive interfaces, and also gain information about elasticity and absoprtion.

Detection, mapping, and quantification of single walled carbon nanotubes in histological specimens with photoacoustic microscopy. [PDF]

PLoS ONE, 2012
In the present study, the efficacy of multi-scale photoacoustic microscopy (PAM) was investigated to detect, map, and quantify trace amounts [nanograms (ng) to micrograms (µg)] of SWCNTs in a variety of histological tissue specimens consisting of cancer ...

Data processing for acoustic probe microscopy techniques [PDF]

, 2012
One of the merits of acoustic probe microscopy techniques is the possibility of exploiting traceable quantitative mechanical characterization of surfaces. To this end, after measurement proper data processing is needed in order to eliminate or compensate
