Activatable Photoacoustic Nanoprobes for In Vivo Ratiometric Imaging of Peroxynitrite
Organic semiconducting nanoprobes doped with bulky borane can undergo specific activation by ONOO− even at tumor-relevant acidic pH (6.8), permitting in vivo ratiometric photoacoustic imaging of ONOO− in the tumor environment ...
In Situ Synthesis of Gold Nanostars within Liposomes for Controlled Drug Release and Photoacoustic Imaging
This report describes the design and synthesis of gold nanostars (AuNSs) containing liposomes by the in situ reduction of gold precursor, HAuCl4 (pre-encapsulated within the liposomes) through HEPES diffusion and reduction. ...
Self-quenched semiconducting polymer nanoparticles for amplified in vivo photoacoustic imaging
Development of photoacoustic (PA) imaging agents provides opportunities for advancing PA imaging in fundamental biology and medicine. Despite the promise of semiconducting polymer nanoparticles (SPNs) for PA imaging, the ...
