A dual-channel lipid droplet-targeting probe for the detection of polarity and HOCl in models of NAFLD, inflammation, and cancer
Abnormal lipid droplet accumulation and metabolism can precipitate various diseases. Understanding the dynamics of intracellular lipid droplets, particularly hypochlorite acid (HOCl) and polarity, is crucial for elucidating the onset and progression of these diseases. In this study, we synthesized a near-infrared fluorescent probe, NSSP, featuring a D-π-A structure, which facilitates the independent dual-response detection of HOCl and polarity. NSSP not only reveals the polarity and HOCl fluctuations in inflammatory cells and inflammation in live mice but also differentiates between normal and fatty liver tissues through two distinct channels. Furthermore, the probe has proven effective in identifying neoplasms within live murine models at both the cellular and systemic levels, thereby affirming its utility as an instrumental resource for the precocious detection of carcinomas. This offers a hopeful avenue for the diagnostic scrutiny of pathologies.
期刊介绍：
As a peer-reviewed journal for analytical sciences and technologies on the micro- and nanoscale, Microchimica Acta has established itself as a premier forum for truly novel approaches in chemical and biochemical analysis. Coverage includes methods and devices that provide expedient solutions to the most contemporary demands in this area. Examples are point-of-care technologies, wearable (bio)sensors, in-vivo-monitoring, micro/nanomotors and materials based on synthetic biology as well as biomedical imaging and targeting.
