Abstract:Macrophage performs multiple functions such as pathogen phagocytosis, antigen presentation and tissue remodeling by polarizing toward a spectrum of phenotypes. Dynamic imaging of macrophage phenotypes is critical for evaluating disease progression and the therapeutic response of drug candidates. However, current technologies cannot identify macrophage phenotypes in vivo. Here, we develop a surface‐enhanced Raman scattering (SERS) nanoprobe, AH1, which enables the accurate determination of physiological pH with… Show more
