Multi-Quartz Enhanced Photoacoustic Spectroscopy with Different Acoustic Microresonator Configurations

Journal of Spectroscopy, 2015
Acoustic microresonators were added to the recently developed multi-QTF based QEPAS spectrophone to enhance the signal amplitude. Two kinds of “on-beam” configurations were experimentally investigated in detail.

In Vitro and In Vivo Photothermal and Photoacoustic Activities of Polymeric Nanoparticles Loaded with Nickel, Palladium, and Platinum‐Bis(dithiolene) Complexes

ChemMedChem, Volume 20, Issue 12, June 17, 2025.
Molecular metal‐bis(dithiolene) photothermal agents are efficiently incorporated into water‐dispersible nanoparticles (NPs) constituted by a biocompatible polymer derived from poly(malic acid). The photoacoustic activity of these NPs is evaluated, and their photothermal properties under near‐infrared irradiation are used for photothermal therapy of ...
