Molecular specific optoacoustic imaging with plasmonic nanoparticles

Optics Express, 2007
Gold nanoparticles functionalized with antibodies can specifically bind to molecular biomarkers such as epithelial growth factor receptor (EGFR). The molecule specific nature of the antibody-functionalized gold nanoparticles forms the basis for the developed optoacoustic imaging technique to detect cancer at an asymptotic stage.

[Optoacoustic spectroscopy and imaging].

Zeitschrift fur medizinische Physik, 2002
Optoacoustic methods are based on the thermoelastic effect, according to which a short laser pulse is absorbed in a medium and generates an acoustic wave following rapid heating and thermal expansion. This study it sought to demonstrate how the optical properties and structure of the sample can be obtained from acoustic signals that are measured on the

Low frequency detection in clinical multispectral optoacoustic tomography

Photoacoustics
Frequency response characterization of optoacoustic (photoacoustic) detectors is critical because the signals are broadband, and the center frequency relates to the absorber size.

Multi‐Scale Volumetric Dynamic Optoacoustic and Laser Ultrasound (OPLUS) Imaging Enabled by Semi‐Transparent Optical Guidance

Advanced Science
Major biological discoveries are made by interrogating living organisms with light. However, the limited penetration of un‐scattered photons within biological tissues limits the depth range covered by optical methods.
