Preparation of Surface Dispersed WO/BiVO Heterojunction Arrays and Their Photoelectrochemical Performance for Water Splitting.

In this work, a surface dispersed heterojunction of BiVO-nanoparticle@WO-nanoflake was successfully prepared by hydrothermal combined with solvothermal method. We optimized the morphology of the WO nanoflakes and BiVO nanoparticles by controlling the synthesis conditions to get the uniform BiVO loaded on the surface of WO arrays. The phase composition and morphology evolution with different reaction precursors were investigated in detail.

Sequentially sustained release of anticarcinogens for postsurgical chemoimmunotherapy.

Postsurgical treatment is of great importance to combat tumor recurrence and metastasis. Anti-CD47 antibodies (aCD47) can block the CD47-signal regulatory protein-alpha (CD47-SIRPα) pathway to restore immunity. Here, an in-situ gel implantation was engineered by crosslinking chitosan (CS) and pullulan (Pul) for postsurgical treatment.

A bio-responsive, cargo-catchable gel for postsurgical tumor treatment via ICD-based immunotherapy.

Tumor recurrence and metastasis after surgery remain challenges for tumor treatment. Strategy that can promote the immunogenicity, activate adaptative immune response and eliminate post-operative immunosuppression would be a promising way to achieve a desired clinical benefit. In this study, immunogenic cell death (ICD) priming anti-tumor adaptive immune response was executed to potentiate immune checkpoint blockade (ICB) therapy through the PD1/PDL1 pathway for postsurgical treatment.

pH-dependent reversibly activatable cell-penetrating peptides improve the antitumor effect of artemisinin-loaded liposomes.

Artemisinin (ART) is well known as an antimalarial drug, and it can also be used to treat inflammation as well as cancer. Although many researchers have reported the antitumor activity of ART, most of these studies were investigated in vitro. In addition, ART is sparingly soluble in water, limiting its clinical relevance in drug development.
