Platelet Activation-Induced In Situ Trapping Metastatic Tumor Cells Strategy for Post-Surgery Tumor Recurrence Immunochemotherapy.

The reasons for the high recurrence and metastasis after triple-negative breast cancer (TNBC) surgery are the potential presence of micrometastases and disseminated tumor cells in the circulation, as well as the immunosuppressive microenvironment caused by the surgery. To address these issues, this work proposed a platelets (PLTs) based hydrogel delivery system for immuno-chemotherapy, (IL-12+NP-PLT)@dAlg. To utilize the targeting ability of PLTs toward tumor cells and maintain the activity of PLTs, doxorubicin-loaded nanoparticles (NP) were attached on the surface of PTLs (NP-PLT).

Photonics-aided exceeding 200-Gb/s wireless data transmission over outdoor long-range 2 × 2 MIMO THz links at 300 GHz.

Outdoor long-range terahertz (THz) communications often come at the expense of transmission rate. Moreover, the practicability of the single polarization optical/THz link, which is commonly used in the previous long-range THz demonstrations based on photonics, is extremely limited by the following two fatal defects. One is relying on active polarization control, and the other is not supporting the transparent bridging of optical polarization division multiplexed (PDM) signals for mature coherent optical communication networks.

Machine learning-assisted high-throughput screening of transparent organic light-emitting diode anode materials.

Securing optimal work functions for two-dimensional (2D) nanomaterials in Organic Light-Emitting Diodes (OLEDs) is crucial for enhancing the internal quantum efficiency of a device.

Here, we propose a target-driven material design framework that combines high-throughput virtual screening and interpretable machine learning (ML) to accelerate the discovery of transparent OLED anode materials.
