Multicolor nanobubbles for FRET/ultrasound dual-modal contrast imaging

Abstract

The aim of this paper is to develop a novel fluorescence/ultrasound dual-modal contrast agent. We prepared multicolor nanobubbles by doping with three fluorescent dyes for combined fluorescence and contrast enhanced ultrasound imaging. The nanobubbles based on fluorescence resonance energy transfer (FRET) with different doping dye ratio combinations exhibited multiple colors under single wavelength excitation, allowing multiplexed assays for various biomedical applications. In vitro and in vivo ultrasound imaging indicated that nanobubbles have great contrast enhancement capability. In vivo fluorescence imaging showed the excellent ability to provide simultaneous multicolor imaging. The novel multicolor nanobubbles may have great potential for a variety of applications in the study of life science and clinical medicine.
