Phase‐Change Peptide Nanoemulsions
Real‐time monitoring of immune cells in tissues holds promise to improve disease diagnosis and therapy. In article number 2301673, Scott H. Medina and co‐workers report the ultrasound imaging of macrophages in situ using phase‐changing peptide nanoemulsions. After phagocytosis, the emulsion contrast agent can be converted into echogenic bubbles to enable precise...
Macrophages are specialized phagocytes that play central roles in immunity and tissue repair. Their diverse functionalities have led to an evolution of new allogenic and autologous macrophage products. However, realizing the full therapeutic potential of these cell‐based therapies requires development of imaging technologies that can track immune cell migration within tissues in real‐time. Such innovations...
