Epithelial mesenchymal transition (EMT) of tumor cells is recognized as the main driver to promote metastasis. Extensive researches suggest that gradually decreased E‐cadherin (E‐cad) and increased N‐cadherin (N‐cad) exist in the tumor cells during the EMT process. However, there still lacks suitable imaging methods to monitor the status of EMT for evaluating tumor metastatic potentials. Herein, the...
A series of polybutadiene‐graft‐polystyrene (PB‐g‐PS) graft copolymers with different core–shell ratios (PB/PS) are synthesized using emulsion polymerization. Subsequently, the PB‐g‐PS graft copolymers are blended with polyphenylene oxide (PPO) and polystyrene (PS) to prepare PPO/PS/PB‐g‐PS blends with varying compositions. The effects of the core–shell ratio of PB‐g‐PS graft copolymer and matrix...
Ultrasound molecular imaging (UMI) has shown promise for assessing the expression levels of biomarkers for the early detection of various diseases. However, it remains difficult to simultaneously image multiple biomarkers in a single systemic administration, which is important for the accurate diagnosis of diseases and for understanding the dynamic intermolecular mechanisms that drive their malignant...
