Photoacoustic tomography (PAT) is a newly emerging noninvasive imaging modality that could be further enhanced using near-infrared (NIR)-absorbing materials as contrast agents. To date, the most extensively studied photoacoustic imaging agents are inorganic nanomaterials because organic materials with NIR-absorption capabilities are limited. In this study,(More)
Objective: Photoacoustic (PA) tomography (PAT) has attracted extensive interest because of its optical absorption contrast and ultrasonic detection. This study aims to develop a biocompatible and biodegradable PA contrast agent particularly promising for clinical applications in human body. Methods: In this study, we presented a PA contrast agent: 1,(More)
Osteosarcoma (OS) is the most common form of bone malignancy in children and adolescents. A class of molecules known as microRNAs (miRNAs) have been routinely associated in the development and progression of OS. The present study was centered on the less well-known miRNA, miRNA (miR)-150, and its role in OS was investigated. The levels of miR-150 were(More)
We report the electrical control of magnetization in multiferroic LuFe2O4 by applying short current pulses. The magnitude of the induced magnetization change depends on the pulse width and current density. The voltage variation during the applied current pulses evidences an electric-field-induced breakdown of charge order and excludes the role of Joule(More)
