Photodynamic therapy(PDT) has emerged as a potential clinical strategy for tumor therapy. It can generate reactive oxygen species(ROS) to cause the chemical damage of tumor cells and promote the immune killing effects of T cells on tumor cells in the presence of enough oxygen and PDT drugs. However, most solid tumors are in a state of oxygen deficiency, which seriously limit the efficacy of PDT in generation enough ROS. Besides, few safe PDT drugs with ideal pharmacokinetic behavior are available in the clinic,which severely limits the clinical transformation and application of PDT. Herein, we utilized manganese chloride to mineralize the hydrophilic indocyanine green/albumin polyplexes(ICG@BSA@MnO_(2)) by using bio-mineralized method to solve these problems of PDT. These ICG@BSA@MnO_(2)nanoparticles could circulate in the blood for a long period other than quickly removed from body after 30 min like free *** accumulated at the tumor site, ICG was responsively released in the presence of hydrogen peroxide. Apart this, the tumor hypoxia microenvironment was also reversed owing to enhanced O_(2)generation by the reaction of MnO_(2)with hydrogen peroxide. Benefits from the rich accumulation of ICG and ameliorated tumor hypoxia in the tumor sites, the enhanced generation of ROS could successfully promote the distribution of CD3^(+) and CD8^(+)T cells inside the tumors, which then lead to the amplified efficacy of PDT in both CT26 and B16 F10 tumor models without causing any side effects.

The hierarchical BiOX(X=Cl, Br, I) microflowers were successfully synthesized via simple precipitation method at 160 ℃ for 24 h and characterized by XRD, SEM, TEM, UV-vis DRS and N_2 adsorption-desorption techniques. The as-prepared samples were pure phases and of microflowers composed of nanosheets which intercrossed with each other. The specific surface areas were about 22.9, 17.3 and 16.2 m^2/g for BiOCl, BiOBr and BiOI, respectively. The photocatalytic activities of BiOX powers were evaluated by RhB degradation under UV-vis light irradiation in the order of BiOCl > BiOBr > BiOI. Also, the kinetics of RhB degradation over BiOI was selectively investigated, demonstrating that the kinetics of Rh B degradation follows apparent first-order kinetics and fits the Langmuir-Hinshelwood model.

Research on two-dimensional(2D) materials has been explosively increasing in last seventeen years in varying subjects including condensed matter physics, electronic engineering, materials science, and chemistry since the mechanical exfoliation of graphene in 2004. Starting from graphene, 2D materials now have become a big family with numerous members and diverse categories. The unique structural features and physicochemical properties of 2D materials make them one class of the most appealing candidates for a wide range of potential applications. In particular, we have seen some major breakthroughs made in the field of 2D materials in last five years not only in developing novel synthetic methods and exploring new structures/properties but also in identifying innovative applications and pushing forward commercialisation. In this review, we provide a critical summary on the recent progress made in the field of 2D materials with a particular focus on last five years. After a brief backgroundintroduction, we first discuss the major synthetic methods for 2D materials, including the mechanical exfoliation, liquid exfoliation, vapor phase deposition, and wet-chemical synthesis as well as phase engineering of 2D materials belonging to the field of phase engineering of nanomaterials(PEN). We then introduce the superconducting/optical/magnetic properties and chirality of 2D materials along with newly emerging magic angle 2D superlattices. Following that, the promising applications of 2D materials in electronics, optoelectronics, catalysis, energy storage, solar cells, biomedicine, sensors, environments, etc. are described sequentially. Thereafter, we present the theoretic calculations and simulations of 2D materials. Finally, after concluding the current progress, we provide some personal discussions on the existing challenges and future outlooks in this rapidly developing field.
