“…For versatile antitumor therapy, the combination of PDT and PTT is usually adopted by researchers for their common characteristics (noninvasive property and the dependence of light) as well as imaging guidance of photothermal agents, and this strategy exhibits significant potential. − At the same time, the exploration of up-conversion materials is always one focus in the field of versatile PDT/PTT antitumor strategy. For example, the preparation and functional development of up-conversion materials with CQDs have attracted great attention from researchers in biomedicine, bioimaging, and optoelectronics. − However, CQDs play only an auxiliary role rather than being the core members for light utilization in recent research. For another, there are some reports of PDT that does not rely on traditional up-conversion materials in tumor therapy, , such as synthetic GO and CuS nanocrystals, which are demonstrated to contribute to a dual PTT/PDT treatment for tumor therapy under near-infrared light but also show obvious defects, such as high cost and potential security concerns.…”

Photodynamic therapy (PDT), a promising noninvasive tumor treatment strategy, is limited by poor biocompatibility, high cost, and complicated synthesis procedures of rare-earth up-conversion materials. Herein, natural melanin particles (MNPs), excellent photothermal therapy (PTT) materials, were found to significantly promote production of reactive oxygen species (ROS) under 808 nm irradiation when cross-linked with C60, whereas synthetic polydopamine had no such property. On the basis of this special character of MNP, MNP-C60-hyaluronic acid (MC60H) nanoparticles, independent of rare-earth up-conversion materials, were prepared for multimodal attack toward a tumor under 808 nm irradiation. After targeting recognition by hyaluronic acid (HA), MC60H could not only efficiently promote temperature rise and the production ROS in tumor but also activate the prominent immunotherapy and help tumor immunosuppressed M2-type macrophages transformed into antitumor M1-type. Under the premise of high biosecurity and simple preparing strategy, the versatile nanoparticle material, MC60H, is utilized for collaborative PTT, PDT, and immunotherapy under NIR excitation without participation of any rare-earth elements. The character of promoting ROS production of C60 by MNP, which is a natural biomaterial, is first reported in this paper, which provides a good demonstration of MC60H in application of a synergistic antitumor strategy without the dependence of traditional up-conversion material.

Two-dimensional materials hold great potentials for beyond-CMOS (complementary metal−oxide−semiconductor) electronical and optoelectrical applications, and the development of field effect transistors (FET) with excellent performance using such materials is of particular interest. How to improve the performance of devices thus becomes an urgent issue. The performance of FETs depends greatly on the intrinsic electrical properties of the channel materials, meanwhile the device interface quality, such as extrinsic scattering of charged impurities, charge traps, and substrate surface roughness have a great influence on the performance. In this paper, the impact of the interface quality on the carrier diffusion behaviors of monolayer (ML) MoSe 2 has been investigated by using an in situ ultrafast laser technique to avoid the surface contamination during device fabrication process. Two types of selfassembled monolayers (SAMs) are introduced to modify the gate dielectric surface through an interface engineering approach to obtain chemical−stable interfaces. The results showed that the transport properties of ML MoSe 2 were enhanced after interface engineering, for example, the carrier mobility of ML MoSe 2 was improved from ∼59.4 to ∼166.5 cm 2 V −1 s −1 after the SAM modification. Meanwhile, the photocarrier dynamics of ML MoSe 2 before and after interfacial engineering were also carefully studied. Our studies provide a feasible method for improving the carrier diffusion behaviors of such materials, and making them suited for application in future integrated circuit.

“…30 In addition, the peak at 3435 cm −1 is ascribed to the stretching vibrations of surface-adsorbed water. 31 The FTIR pattern of HTCC/Fe-ATP covers most characteristic peaks of HTCC and Fe-ATP, which indicates that the composites of Fe-ATP and HTCC still maintain their main backbone structures.…”
