Abstract
Neuroinflammation is a significant pathological event involving the neurodegenerative process associated with many neurological disorders. Diagnosis and treatment of neuroinflammation in its early stage are essential for the prevention and management of neurological diseases. Herein, we designed macrophage membrane-coated photoacoustic (PA) probes (MSINPs), with targeting specificities based on naturally existing target-ligand interactions for the early diagnosis of neuroinflammation. The second near-infrared dye, IR1061, was doped into silica as the core and was encapsulated with a macrophage membrane. In vitro as well as in vivo, the MSINPs could target inflammatory cells via the inflammation chemotactic effect. PA imaging was used to trace the MSINPs in a neuroinflammation mouse model and showed a great targeted effect of MSINPs in the prefrontal cortex. Therefore, the biomimetic nanoprobe prepared in this study offers a new strategy for PA molecular imaging of neuroinflammation, which can enhance our understanding of the evolution of neuroinflammation in specific brain regions.

Abstract
Quercetin (QU), a natural flavonoid with potent anti-inflammatory and antioxidant properties, holds promise in treating acute liver injury (ALI). Nonetheless, its limited solubility hampers its efficacy, and its systemic distribution lacks targeting, leading to off-target effects. To address these challenges, we developed macrophage membrane-coated quercetin-loaded PLGA nanoparticles (MVs-QU-NPs) for active ALI targeting. The resulting MVs-QU-NPs exhibited a spherical morphology with a clear core-shell structure. The average size and zeta potential were assessed as 141.70 ± 0.89 nm and -31.83 ± 0.76 mV, respectively. Further studies revealed sustained drug release characteristics from MVs-QU-NPs over a continuous period of 24 h. Moreover, these MVs-QU-NPs demonstrated excellent biocompatibility when tested on normal liver cells. The results of biodistribution analysis in ALI mice displayed the remarkable ALI-targeting ability of MVs-DiD-NPs, with the highest fluorescence intensity observed in liver tissue. This biomimetic approach combining macrophage membranes with nanoparticle delivery, holds great potential for targeted ALI treatment.

Abstract
Acute pancreatitis (AP) is a common and life-threatening digestive disorder. However, its diagnosis and treatment are still impeded by our limited understanding of its etiology, pathogenesis, and clinical manifestations, as well as by the available detection methods. Fortunately, the progress of microenvironment-targeted nanoplatforms has shown their remarkable potential to change the status quo. The pancreatic inflammatory microenvironment is typically characterized by low pH, abundant reactive oxygen species (ROS) and enzymes, overproduction of inflammatory cells, and hypoxia, which exacerbate the pathological development of AP but also provide potential targeting sites for nanoagents to achieve early diagnosis and treatment. This review elaborates the various potential targets of the inflammatory microenvironment of AP and summarizes in detail the prospects for the development and application of functional nanomaterials for specific targets. Additionally, it presents the challenges and future trends to develop multifunctional targeted nanomaterials for the early diagnosis and effective treatment of AP, providing a valuable reference for future research.
