Author(s):Vinoin Devpaul Vincely, Xingjian Zhong, Kristie Huda, Swathi P. Katakam, Joshua C. Kays, Allison M. Dennis, Carolyn L. Bayer ABSTRACT In this study, we demonstrate the potential of the bornite crystal structure (Cu5FeS4) of copper iron sulfide as a second near infrared (NIR-II) photoacoustic (PA) contrast agent. Bornite exhibits comparable dose-dependent biocompatibility to copper sulfide nanoparticles in a cell viability study with HepG2 cells, while exhibiting a 10-fold increase […]

A COMBINED ULTRASOUND AND PHOTOACOUSTIC IMAGING PLATFORM FOR CLINICAL RESEARCH APPLICATIONS
Author(s): Weylan Thompson, Hans-Peter Brecht, Sergey A. Ermilov, Vassili Ivanov ABSTRACT We present the continued development of a clinical ultrasound (US) imaging device with a photoacoustic (PA) mode. The combined USPA imaging platform is designed around a compact US component capable of B-mode, M-mode, color Doppler, and pulsed wave Doppler US imaging modes with a 128-element US probe. […]
