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 ...

Lens geometries for quantitative acoustic microscopy

, 1995
Chapter 4The purpose of the first Lemons-Quate acoustic microscope(1) was to image the surfaces of materials or biological cells with a high resolution. Unfortunately, competition with the optical microscope was only partially successful due to the high ...
